EXECUTIVE SUMMARY
Titas Gas Transmission and Distribution Company Ltd(TGTDCL),a subsidiary company of
Bangladesh Oil, Gas and Mineral corporation(Petrobangla),is a pioneering organization in
natural gas sector. B.Baria, greater Dhaka and Mymensingh districts comprises its franchise
area. Titas gas provides about 72% of the total gas consumed in the country. Titas Gas
supplies gas to a variety of customers such as industry, commercial etc. Natural Gas being
non-renewable energy is limited but valuable resource of Bangladesh. Bangladesh economy
especially the industrialization process largely depends on the smooth supply or natural gas.
Noteworthy that the demand of gas for various categories of customers is on the increase. So
it is important to forecast the demand of gas in the coming years. Not only that it is also
important to analysis the gas reserve scenario, system loss, and production perspective of
natural gas to cater to the requirement of natural gas in the coming years. Thus the objectives
of the study have been set so. It is worth mentioning that system loss is the difference
between the volume of natural gas purchased from producers and the volume of natural gas
supplied to the customers.
Time series analysis, which is based on regression analysis, is an important tool for
forecasting any variable /economic data. Hence to meet the objectives of the study this toolhas been employed to develop a suitable regression model with which to forecast the gas
demand and system loss within Titas Gas T & D Co. Ltd, using relevant secondary data
collected from this company and Petrobangla. Using this model forecasting of gas demand
and system loss for next 15(fifteen) years is made. It is found that forecasted totas gas
demand for the next 15(fifteen) years would be 4730490.243 million cubic feet which is
33.905% of the remaining gas reserve. This suggests that the remaining reserve will cater to
the growing gas demand within Titas franchise area for more than 15(fifteen) years. It may
be up to approximately 45 (forty five) years. And to face this need production of gas is to be
enhanced 29.2265% per year. As to system loss analysis it is found that system loss of the
company is on the decline. It is also found that system loss is not well explained by time
alone. There might be other factor/factors to describe this.

It is imperative that the policy makers of the gas sector would think well ahead of time to
explore and research for more natural gas resources and to increase the present production
level to conform to the forecasted gas demand with a view to avoiding uncertainties in gas
sector.

CHAPTER 01
INTRODUCTION
1.1. Background and present status of gas sector:
Bangladesh is a land of some natural resources such as oil, gas, coal, hard rock, white clay,
boulder etc. Bangladesh being the biggest delta in the world, serves as a good reservoir of
Natural Gas. Exploration and production of Natural Gas is undertaken by Bangladesh Gas
Fields Company Limited (BGFCL), Sylhet Gas Fields Limited (SGFL), Bangladesh
Petroleum Exploration and Production Company Limited (BAPEX), Some International Oil
Companies (IOC). They are producing natural gas from 12 fields. The average daily
production of these gas fields in fiscal year 2005-2006 is 1500 MMSCF and yearly
production is 540 BCF (Annual Report of Petrobangla 2005-2006). Gas Transmission Lines
are handled by Gas Transmission Company Limited (GTCL). There are four separate
distribution companies that are engaged in supplying Natural Gas to different types of
customers in different regions. They construct and handle distribution lines and conduct
marketing activities. A company named Rupantarita Prakritik Gas Company Limited
(RPGCL) was organized to convert vehicles to Compressed Natural Gas (CNG) and to
popularize the use of CNG. Barapukuria Coal Mine Company (BCMC) and Madhyapara
Granite Mining Company Limited (MGMCL) are two companies that serve the purpose of
mining of coal and hard rock respectively. A corporate body under the ministry of petroleum
and mineral resources Petrobangla supervises all of the above companies in the country.
Gas consumption arenas are Power plants, Fertilizer factories, Process plants, different types
of Industries, Commercial and Domestic customers etc.
The discovery of large reserve of natural gas has stimulated demand for this clean, cost-
effective energy source, resulting in rising investment and rapid expansion of transmission
and distribution networks. Because of versatile use of natural gas in the industrialization
process ( Natural gas is used as raw materials and environment friendly fuel of high calorific
value) , its demand is increasing day by day. Thus it is necessary to forecast the demand of
natural gas .

1.2 . Objective of the study:
a.To forecast the demand of gas in various category of gas connection within the Titas
franchise area.
b.To analyze and forecast the system loss that incurs within Titas franchise area in
transmission and distribution of gas.
c.To forecast the relationship between the remaining reserve of gas and the cumulative
forecasted demand of gas after 15(fifteen) years from now.
d.To forecast the growth in production scenario of gas.
1.3. Rationale of the study:
This study may provide the decision makers of the NATURAL GAS sector with the
basis of decision. This may give us an insight into the relationship amongst demand,
supply/production and reserve scenario of natural gas. Natural gas being crucial sector
of Bangladesh, knowledge surrounding this sector may enable us to avoid
uncertainties.
1.4. Limitation of the study: In this study, forecasting of gas demand and system loss is
carried out for Titas Gas T & D Co. Ltd only, which captures 72.52% of the total market
share of Natural Gas. But total forecasted gas demand is compared with total remaining gas
reserve. Analysis has been done based on secondary data.

CHAPTER 02GAS SECTOR OF BANGLADESH
2.1.History of Petrobangla:Bangladesh Mineral, Oil & Gas Corporation (BMOGC) was created through the Presidential
Order # 27 on 26 March 1972. The Minerals operation of the corporation was segregated and
vested with a new organization, Bangladesh Mineral Exploration and Development
Corporation (BMEDC) though the Presidential Order #120 of 27 September 1972. The
reconstituted Bangladesh Oil & Gas Corporation (BOGC) was short-named Petrobangla
through the Ordinance # 15 of 22 August 1974. Through the repeal Ordinance # LXX of
1974, Oil and Gas Development Corporation was abolished and all its asset and liabilities
was vested to Petrobangla. On 13 November I976, through the Ordinance # 88, the
importation, refining and marketing of crude and petroleum products was vested with the
newly formed Bangladesh Petroleum Corporation (BPC). BOCC and BMEDC were merged
into a single entity, Bangladesh Oil, Gas & Mineral Corporation (BOGMC) by the Ordinance
# 21 of 11 April 1985. In a partial modification of the Ordinance by the Act # 11 of February
1989, the Corporation was short-named Petrobangla and given the authority to hold the
shares of the companies dealing in oil, gas & minerals exploration and development.
Mandate of Petrobangla:
Bangladesh oil, Gas & Mineral Corporation ( Petrobangla), is empowered and entrusted of
perform:
Exploration and development of the Oil, Gas and Mineral Resources as per the
policies of the Government of the Peoples Republic of Bangladesh.
Coordinate, plan and supervise the activities of the subordinate companies.
Overall control and coordination of the production, transmission and marketing ofgas, condensate, oil and mineral resources produced in the country
Conduct necessary research required in Oil, Gas and Mineral Exploration.
Enter into Production Sharing Contracts (PSC) with International Oil Companies
for exploration and development of Oil and Gas and to supervise, monitor and
coordinate the activities under the signed PSCs.
To implement important projects to develop the gas and mineral sector with the
annual government fund and assistances provided by the friendly countries and
international organizations.
Any other functions and responsibilities as directed by the government from time
to time.
2.2.OPETROBANGLA AND THE GOVERNMENT
Petrobangla operates as public sector statutory body under the ordinance of 1985. The Board
of Directors is the policy making and managing body of the Corporation, with members
from various Ministries The Corporation is under the administrative control of the Energy
and Mineral Resources Division the Ministry of Power, Energy and Mineral Resources, The
Corporation have also relationship, through the Ministry of Power, Energy and Mineral
Resources, with Ministry of Finance and Ministry of Planning for its development
programmes. There is also active relationship with numerous functional bodies such as,
National Board of Revenue, Department of Explosives, and Department of Environment for
specific work functions. The activities of the Corporation is reviewed and examined by the
Public Accounts Committee and the Parliamentary Standing Committee on Power, and

Mineral Resources.
2.3. SHORT HISTORY OF OIL, GAS & MINERAL INDUSTRY IN BANGLADESH
The beginning: up to 1947
The search of oil and gas in the area constituting Bangladesh began in the later part of the19th century through some isolated geological mapping. The first serious attempt to find oil
and gas was undertaken in Staked in 1908 by the Indian Petroleum Prospecting Company, 18
years after the first oil discovery in Digboi, Assam. During 1923-31 Burma Oil Company
(BOC) drilled two shallow wells in Path aria. The wells were abandoned though there was a
reported show of oil. A total of 6 exploratory wells were drilled, the deepest being 1047
meters. There was, however, no discovery and the Second World War disrupted further
activities.
The interim: 1947 to 1971
The promulgation of Pakistan Petroleum Act in 1948 infused interest of international oil
companies in oil and gas exploration. The Standard Vacuum Oil Company (STANVAC) ofUSA, Pakistan Petroleum Ltd. (PPL)-a Burma Oil Company affiliate, and Pakistan Shell Oil
Company (PSOC) took up concessions during early fifties and carried out exploration till the
end of the sixties. STANVAC drilled 3 wells at Hazipur, Bogra and Kuchma in the
northwestern part of the country without success. PPL drilled wells in Haripur; Patharia,
Chhattak, Fenchuganj, Patiya and Lalmai and made the first gas discovery in Haripur in
1955, followed by Chhattak in 1959. PSOC was the most successful company and discovered
the 5 gas fields of Titas, Habiganj, Rashidpur; Kailashtila and Bakhrabad. They also drilled
the first offshore well Coxs bazar-1, which was dry.
During this time Oil and Gas Development Corporation (OGDC) was established as the
national organization in 1961 and the root of exploration for oil and gas were set up in the
country. OGDC carried out geological and geophysical survey including gravity, magnetic
and seismic and drilled wells in Jaldi and Semutang, discovering gas in Semutang in 1970.
The way forward : 1971 onwards
After the independence of Bangladesh, exploration activities by both national and
international companies gathered pace. Bangladesh Oil, Gas and Mineral Corporation
(Petrobangla) continued its exploration efforts while the Bangladesh Petroleum Act was
enacted in 1974 to facilitate international participation under PSC. The offshore area of
Bangladesh was divided into 6 blocks, which were taken up by Ashland, ARCO, BODC
(Japex), Union Oil, Canadian Superior Oil and Ina Naftaplin under production sharingcontracts. These companies carried out gravity, magnetic and seismic surveys (about 32000
km) and drilled 7 wells. Of them, only Union Oil Company discovered an offshore gas field
Kutubdia in 1977. This phase of PSC ended with relinquishment of the blocks by the PSC
operators in 1978.
The 1980s saw accelerated exploration activities by Petrobangla, which drilled 12 exploration
wells in Muladi, Begumganj, Singra, Beanibazar; Atgram, Feni, Fenchuganj, Sitakund,
Bogra, Kamta, Marichakandi (Meghna) and Belabo (Narshindi) and discovered 7 gas fields in
Begumganj, Beanibazar, Feni, Fenchuganj, Kamta, Marichakandi (Meghna), and Belabor
(Nearside). Among these, Fenchuganj-2 well remains the deepest drilled well in Bangladesh
(4977m). Meanwhile a new milestone was achieved when Petrobangla discovered the first
commercial oil pool in Sylhet-7 on December 23, 1986. Since 1989, after the formation ofBAPEX as the national exploration company, BAPEX has continued exploration for
-

Petrobangla, and drilled 3 exploratory wells discovering gas in Shahbazpur and Saldanadi.
In 1981 Shei1 Oil Company was awarded the Chittagong Hill Tracts for petroleum
exploration under PSC. Shell conducted geological and seismic survey and drilled the
Sitapahar well which was dry, subsequently Shell undertook exploration in the extreme northwest of the country and drilled the first well in the area - the Salbanhat well which was also
dry. In 1988 Schimitar Exploration was awarded another PSC what is now block 13 in Surma
basin. They failed to prove the extent of the oil discovery at Sylhet structure but discovered
the Jalalabad gas field.
Enactment National Energy Policy 1993 and adoption of a model production sharing contract
document together with redefining the whole of Bangladesh territory into 23 exploration
blocks ushered in a new phase of exploration and development of oil and gas in the country.
In the first stage under the new arrangement, 8 blocks were awarded to 4 companies under
PSC. Exploration and development activities in these blocks were rather limited; most of the
blocks were moderately covered by seismic. So far in total 11 exploration wells were drilledand 3 gas fields were discovered in these blocks. These fields are Maulavibazar; Sangu and
Babiyana. Three gas fields: previously discovered Jalalabad, newly discovered offshore
Sangu and Maulavibazar were developed under PSC and are in production. The first 3D
seismic survey of the country took place in Bibiyana during its appraisal. Bibiyana is
expected to come under production by the end of 2006. Another PSC bidding round during
the late nineties culminated in award of 4 more blocks. These were Shell/Cairn/Bapex in
blocks-5 & 10, Unocal/Bapex in block-7and Tullow / Chevron / Bapex in block-9.
Exploration activity in these blocks have only recently commenced. There have been
substantial activity in block 9 only, where apart from seismic survey including 3D seismic, 3
exploration wells have been drilled.
Even though exploration history of oil and gas in Bangladesh goes back almost a century,
exploration density has remained very low. So far only about 69 exploration wells have been
drilled, which resulted in discovery of 25 gas fields of sizes ranging from than 4 tcf to 25 bcf
GIIP. This indicates the extremely low exploration density but high success rate of 1 in 3
exploration wells. Of the exploration wells, 13 are in the offshore with 2 discoveries and the
rests 56 are on shore with 23 discoveries.
Minerals: Petrobangla is also entrusted with mineral development in the country. While the
exploration part of minerals activity falls under the charter of Geological Survey of
Bangladesh (GSB), subsequent development of economic deposits are undertaken byPetrobangla. Mineral activities were part of the erstwhile Bangladesh Mineral Exploration &
Development Corporation (BMEDC) till its merger. Petrobangla is developing two
underground mines, one for coal at Barapukuria and the other for hard rock at Madhya Para,
which are expected to be on full production by January 2007 and December 2006
respectively. Certain other extraction operation, like limestone, white clay and boulder, are
controlled by the govt through the Bureau of Mineral Development (BMD).
2.4.ACTIVITIES OF PETROBANGLA
The activities of the Petrobangla group encompasses the whole spectrum of the gas sector.
The Companies under Peftobangla are involved in each of the stages from the drill bit to
burner tips. Petrobangla, through its companies, conducts geological and geophysical
exploration by its own crew, drills exploration and development wells by its own rig or byhired contractors, processes the raw gas to pipe line specification, transport the processed gas
-

through an increasing network of high-pressure transmission lines and distributes gas to the
customers, be it a large power plant or fertilizer factory or a single household. Value added
LPG and liquid fuel is extracted from the gas derived NGL and promoting the growing CNG
network for vehicle fuel are also its function. Furthermore, extraction of coal and granite are
also conducted by Petrobangla.
Exploration and Production
Exploration and Production Exploration in the public sector is the responsibility of
Petrobangla company, Bangladesh Petroleum Exploration and Production Company Ltd
(BAPEX). BAPEX also undertakes production activities. The major public sector gas produc-
tion companies, however, are Bangladesh Gas Fields Company Ltd. and Syihet Gas Fields
Limited, which together account for about 70% of gas production during FY 2004-05.
Transmission
High pressure bulk transport of gas is carried out by the specialized Petrobangla company,
Gas Transmission Company Limited (GTCL). It is the state monopoly for gas transportcatering to both public sector and private sector gas producers. Transmission system built by
other companies before GTCL was formed is being rationalised by integrating them with the
GTCL system. A modern SCADA system, fully commissioned recently, provides integrated
supervision and monitoring.
Distribution
Marketing gas to the customers ranging from large power and fertilizer plants to small
households and business is the responsibility of four marketing companies under Petrobangla.
These companies, namely Titas Gas T&D Co., Bakhrahad Gas Systems Ltd., Jalalabad Gas
T&D System Ltd. and Pashimanchal Gas Co. Ltd., each have their own marketing franchise
covered by a fairly extensive distribution system Expansion of gas marketing to the western
part of the county is now a major priority.
CNG and LPG
As some of the gas fields of Bangladesh contain high percentage of liquid, optimized
extraction of this liquid, especially value added LPG is becoming a growing activity.
Popularization of use of CNG as vehicle fuel is carried out under Petrobangla, and over the
last few years this has accelerated considerably. Use of CNGV has resulted in significant
improvement of the urban air quality. Private sector participation in LPG and CNG is actively
encouraged by Petrobangla.
Mining
Petrobangla has also a mining interest in the country.As the pioneer in subsurface mining inthe country, Petrobangia has developed the mines at Barapukuria for coal extraction and at
Madhyapara for granite mining.
Production Sharing Contracta (PSC)
A major activity of Petrobangla is administering the PSCs. Under the Patrobangla Ordinance,
Petrobangla administers and supervises the PSCs signed with IOCs. Currently, blocks
awarded under two rounds of PSC are operational. Under the 1993/94 awards blocks 12,13
and 14 were awarded to Occidental, blocks 15 and 16 to Cairn Energy, blocks 17 and 18 to
Redwood/ Okland and block 22 to UMC. The share holding operator of these blocks have
since undergone several changes.
Under these PSCs the respective operators have conducted varying amount of exploration and
-
7/27/2019 Mba Sadiqul
14/35
development works. In the blocks 12,13 & 14 a total of 5 exploratory wells were drilled and 2
discoveries were made. There was however a massive blowout in one well resulting in loss of
hydrocarbon and other surface assets. The previously discovered Jalalabad field was
developed and is in production since 1998. In blocks 15 & 16 the operator drilled 6
exploratory wells including 4 offshore wells, resulting in discovery of offshore Sangu field.This field is in production since 1997. In blocks 17 & 18 a single offshore well drilled was
found dry. There was practically no exploration work in block 22. Significant parts or whole
of these blocks are now relinquished as per contract.
Under the second bidding rounds, four blocks have been awarded. Unocal Bangladesh was
awarded block 7, Shell/ Cairn JV was awarded blocks 5 and 10 with a 10% carried stake for
BAPEX, and Tullow,/ Chevron/ Texaco JV was awarded block 9 with a 10% carried stake
for BAPEX. Among these blocks, some seismic survey have been carried out in block 10,
while in block 9 major seismic survey including a 3D survey have been completed followed
by 3 exp1oration wells. An appraisal program is currently underway in block 9 after
encountering significant gas in Bangora-Lalmai.
There has been some restructuring of the holdings in the PSC during the last year. Shell
Bangladesh has handed over their major stake to Cairn Energy, while Chevron Texaco has
transferred their stake in block 9 to Niko Resources. Cairn produced about 47.36 bcf gas and
19,900 bbls condensate from the Sangu field during 2004-05, while Unocal produced 68.88
bcf gas & 663,133 bbls condensate from Jalalabad field and 7.32 bcf gas & 5,511 bbls
condensate from Maulavi Bazar field. Subsequently, all block holdings & operation of
Unocal has been taken over by Chevron as part of their global acquisition of Unocal. Niko is
operating the Feni field in a JV with Bapex produced 6.98 bcf gas during this period.
Production for July to December 2005 were Cairn 29.33 bcf, Unocal 49.21 bcf and Niko 5.10
bcf.
2.5.PETROBANGLA COMPANIES
Over the years, the activities of Petrobangla has expanded and diversified to a great extent.
To manage these activities, Petrobangla has created specialized companies to perform
specific operations. Currently, there are eleven companies operating under Petrobangla,
dealing in oil and gas exploration, production, transmission, distribution, conversion as well
as development and marketing of coal and hard rock.

2.5.1.Bangladesh Petroleum Exploration and Production Company Limited
(BAPEX)
BAPEX is the lone public sector company conducting exploration for oil and gas in thecountry. It was formed by separating the erstwhile exploration directorate of Petrobangla.
The company has the capability of conducting seismic survey and drilling by using its
own manpower and equipment. The company also has laboratory and computerprocessing facilities. So far BAPEX has discovered-two gas fields, Shahbazpur (1996)
and Saldanadi (1997). Since 1998, BAPEX has been converted to an Exploration and
Production Company and owns Saldanadi, Shahbazpur and Fenchuganj gas fields.BAPEX started drilling the exploration well in Srikail in 2004 and completed drilling in
2005 where gas was encountered. It is now under evaluation. As part of developing the
Shahbazpur and Fenchuganj gas fields, BAPEX has undertake the work over of well no.1
and drilling of well no. 2 of the Shahbazpur gas field under Shahbazpur gas fielddevelopment project. The well no. 3 in Fenchuganj was completed and put on production.
BAPEX had also undertaken the drilling of 2 development wells in Titas gas field on
behalf of BGFCL and completed the drilling of well no 15. It has completed an appraisal
2D survey over Narshingdi field for BGFCL. Under the second bidding rounds BAPEXholds 10% shares in the blocks 5,7,9 and 10. BAPEX also has a joint venture with NIKO
to develop two marginal gas fields. In a major breakthrough for the company, it wasawarded the Block 8 and 11 for exploration and development; as part of the programmed
BAPEX has conducted 252 km geological survey in the block 11 during this year. The
two producing gas fields under BAPEX, Saldanadi and Fenchuganj Gas Field, producedabout 17.47 bcf gas and 8,206 bbls of condensate during 2004-05 (up to end June 2005)
The production of gas and condensate for the period from July to December 2005 were
11.00 bcf and 5,079) bbls respectively.
2.5.2.Bangladesh Gas Fields Company Limited (BGFCL)
BGFCL originated as a Shell subsidiary in early sixties operating on a small scale in Titas
and Habiganj gas fields. After the independence of Bangladesh, the Government bought
out the stake and BGFCL became a national company. Today, BGFCL is the largest gasproduction company of the country and operates Titas, Habiganj, Bakhrabad, Meghna
and Narshingdi gas fields. It also operated Feni and Kamta gas fields prior to suspension
of production from these gas fields.
With the rapid growth of gas consumption in the country, BGFCL has kept up its
relentless effort to ensure uninterrupted gas supply and implements major projects. As
part of the development activities, BGFCL is drilling two development wells in Titas gasfield with its own resources, one of which (Titas 15) was completed during the financial
year. An appraisal seismic programme has been completed by BAPEX on its behalf and
based on the results, a new well be drilled in Narshingdi gas field. Another new well inHabiganj gas field and several walkovers will also be undertaken finaced by the company
itself. A major 3D appraisal seismic programme over Titas and Bakhrabad gas field is
also being processed with ADB assistance.
During the financial year 2004-2005, BGFCL produced 276.32 bcf gas and 453,097 bbls
of gas derived liquids from its 30 flowing wells; this averages about 757.04 million cubic
feet gas per day. This was an improvement on the 265.14 bcf gas produced during the
15
-
7/27/2019 Mba Sadiqul
16/35
previous year when the daily average was about 726 million cubic feet gas per day.
Production for the period from July to December 2005 is 136.38 bcf gas, which indicates
the continuous growth in gas production.
2.5.3.Sylhet Gas Fields Limited (SGFL)
SGFL was originally owned by Burmah Oil Company. The company was abandoned byBOC and after the independence of Bangladesh, taken over by the Government. The
company currently operates Sylhet, Kailashtila, Rashidpur and Beanibazar gas fields, and
is the second largest gas producer in the country. The company is implementing a twowell programme for the Kailashtila field to augment and sustain production level. In
addition new projects have been taken up to install 2nd MSTE plant, a condensate
fractionation plant and a 3D seismic survey.
During the financial year 2004-2005, SGFL produced 62.31 bcf gas and 531,997 bbls of
gas derived liquids from its 14 flowing wells; this averages about 170.7 million cubic feet
gas per day. The previous years production was 71.45 bcf gas and 532,795 bbls of gas
derived liquids when the daily average was about 196 million cubic feel gas per day.Production for the period from July to December 2005 is 31.95 bcf. The decline in
production is attributed to problems in some wells and depletion of pressure.
2.5.4. Gas Transmission Company Limited (GTCL)
Gas Transmission Company Limited (GTCL) was incorporated on 14th December 1993
under the Companys Act with the aim to separate the high-pressure gas transmissionoperation and management from that of gas marketing companies in the country and
eventually form the national gas grid for centralized control.
The company commenced its business with the operation of 175 kilometer 24 inches
diameter North-South gas transmission pipe line and the 6 inches parallel pipe line inorder to mitigate the gas demand /supply to the central and south-eastern region of the
country and to carry condensate to Ashuganj.
Later the company implemented the Ashuganj-Bakhrabad pipeline (30 inches 59 km)which connected the national gas grid. The company has implemented a national gas grid
SCADA for effective and central control. The company also completed construction of a
gas pipe line to the western zone over the Jamuna Bridge, carrying natural gas to thewestern part of the country for the first-time. This pipe line was extended to Baghabari
where gas is supplied to Baghabari power station of PDB and IPP power station of
Westmont. GTCL has taken over physical possession of several transmission pipelines
from marketing companies.The Company has since implemented the Ashuganj-Habiganjstage (30 inches 54 km) of the Ashuganj-Kailashtila loop. The second stage extending
from Habiganj to Rashidpur (30 inches 28 km) has been successfully completed. It has
also completed the 30 inches/20 inches 60 km Nalka-Bogra pipeline during 2004-05.Two other projects : 20 inches 60 km Gazipur-Savar pipeline under Dhaka-Clean Fuel
and 30 inches 37 km Ashuganj-Manohardi pipeline are fast nearing completion. The
Company had under its operation a network of 833.87 km. high pressure pipe lines up toDecember 2005. The Company has transported 7722.32 million meter gas during the FY
2004-05 which is 16.96% higher than the previous year. During this period the Company
has transported 123.239 million liters condensate, which is 9.5% more than the previous

CHAPTER 03
A BRIEF ABOUT TITAS GAS TRANSMISSION AND DISTRIBUTION
COMPANY LIMITED
3.1.MARKETING AND OPERATIONAL PERFORMANCE:
Gas Purchases-Sales:Based on gas demand and according to allocation of Petrobangla the target for purchaseand sale of gas was set at 10649.02 MMCM and 10181.98 MMCM respectively for the
financial year 2005-2006. The actual figures of gas purchases and sales during the yearwere 10,875.80 MMCM & 10,164.52 MMCM respectively. It is mentionable that the
growth rate of gas purchase and sales was 10.77% and 11.47% respectively.
Measures taken for improving gas supply:
With the gradual expansion of Dhaka City, the number of customers have also
increased. As a result, some times, gas could not be supplied in some areas as per
demand with the existing pipeline network. In some areas, low pressure problems
have been solved by constructing link lines such as Tejgaon, Palton,
Segunbagicha, Fakirerpul, Santinagar, Postagola, Hazaribagh, Mirpur etc. UnderDhaka clean fuel project 92 KM x16" pipeline has been constructed till
November 2006 in and around Dhaka City to solve the low pressure problems indistribution system & to supply gas to CNG filling stations. Besides a total of 4
DRS/TBS have already been constructed and modification work of 5 DRS/TBS
has been completed.
Construction of 16"x140 PSIGx12.O km Rajendrapur-Jaydebpur main
pipeline from existing offtake valve in Rajendrapur area to supply moregas distribution area in Jaydebpur, area.
Construction of 4"-12"diax2700 meter distribution line and connection withexisting network in different places to solve low pressure problems inPager Bscic area and industrial area of Satas,Tongi.
Safety Position of High Pressure Praline: Regular patrolling system is essential for
maintaining safety of transmission pipeline. But the number of Companys Patrolmen isinadequate.Therefore, private security service has been engaged for safety of high
pressure pipeline and regular supervision to prevent accident. The task of replacing the
old pipeline by phases has also been taken up to improve safety measures and avoidoperational hazards. Program for environmental safety improvement have also been taken
up.
System Loss:Effective efforts have been undertaken to reduce system loss. The premisesof the Industrial & disconnected customers have been inspected by thespecial teams. In the financial year under review due to sincere efforts put inby Titas Management under the direction of Titas Board, Petrobangla andMinistry, positive result could be achieved from February-06 and system losscould be brought down to 6.47% during the year. System loss has come downto 6.47% compared to 7.06% in the previous year. Necessary steps have
21
-
7/27/2019 Mba Sadiqul
22/35
been taken to bring down system loss to 5%.System loss Reduction Programme:
The Company has been implementing different action plans to reduce overall
system loss/unaccounted for gas by maintaining areawise input-output & fixing
responsibilies, RMS sealing, calibration and replacement of old meters, intensive
vigilance, disconnection of unauthoried gas connection by task force, speedydisposal of court cases, electronic volume corrector(EVC), flow/pressure logging
device etc. Necessary steps are being taken to prepare proper gas bill of all
industrial customers through collection of meter reading by computerisedremote-metering system for reduction of system loss. Necessary measures have
been taken to reduce the present system loss at Narayanganj, Sonargaon Tongi,
Narsingdi, Ashuganj and Brahmanbaria and metro sales zone (Ind. & Com. 1,4.).
A target oriented programme is being implemented by assigning officers tocollect meter reading through frequent visit of the customer premises. Meter
Sealing and testing Programme is being completed Properly and timely.
Despite the best efforts made by the Company and better congenial workingatmosphere, reduction of system loss at a desired level could not be achieved due
to shortage of efficient manpower, construction of unauthorised by-pass line by
the dishonest customers, injunction order of the Honorable Court in favour ofdefaulter customers,
Illegal re-connection from disconnected risers, unauthorised use of
additional appliances/gas load, excess gas consumption by the un-metered domestic customers, interference on RMS and meter tamperingetc. During the year 2005-2006 the figures for net gas purchases andsales stood at I 0,875.80 MMCM and10164.52 MMCM respectively. The
sales figures for Bulk and Non Bulk customers stood at 6133.88 MMCMand 4030.64 MMCM respectively. If system loss is not counted in the Bulksector, then the total system loss will be 14.87%. On the other handrevenue loss of all kinds of customers including Bulk customers stood atTk 23611 crore and system loss is 6.47%.
To reduce system loss and to collect arrear gas bills as per direction often
higher authority, the ompanyformed 19 teams to inspect all the industrialcustomers premises to find out the illegal use of gas by dishonestcustomers. The special teams have inspected 3349 industrial customersfrom 11 December 2005 to 29 January 2006 . Among those customers
249 have been disconnected for illegal use of gas. As per application, thedisconnected customers have been reconnected according to gasmarketing policy 2004 and TK 10 corers have been realised as additionalbill and penalty. The company has given a special opportunity fordomestic Customers to regularizes their illegal connections withoutpenalty from 11-2-2006 to 15-5-2006. A total of 51200 unauthorisedconnections were regularized. It has contributed additional TK. 1.88 croremonthly and 22.50 crore yearly to the companys sales revenue.

CHAPTER 05
TIME SERIES ANALYSIS AND FORECASTING
5.1.TIME SERIES AND FORCASTING:Forecasting or predicting is an essential tool in any decision making process. Its uses vary
from determining inventory requirements for a local shoe store to estimating the annualsales of video games. The quality of the Forecasts management can make is stronglyrelated to the information that can be extracted and used from past data. Time-seriesanalysisis one quantitative method we use to determine patterns in data collected overtime. Time-series analysis is used to detect patterns of change in statistical information
over regular intervals of time. We projectthese patterns to arrive at an estimate for thefuture. Thus, time-series analysis helps us cope with uncertainty about the future.
Variations in Time Series: We use the term time series to refer to any groupof statistical information accumulated at regular internals. There are four
kinds of change, or variation. involved in time-series analysis:
a. Secular trendb. Cyclical fluctuation
c. Seasonal variation.
d. Irregular variation
Secular trend: With the first type of change, secular trend, the value of thevariable tends to increase or decrease over a long period of time. The steady
increase in the cost of living recorded by the Consumer Price Index is an
example of secular trend. From year to individual year, the cost of living
varies a great deal, but if we examine a long-term period, we see that thetrend is toward a steady increase.
Cyclical fluctuation: The second type of variation seen in a time series is cyclical
fluctuation. The most common example of cyclical. fluctuation is the
business cycle. Over time, there are years when the business cycle hits apeak above the trend line. At other times, business activity is likely to
slump, hitting a low point below the trend line. The time between hitting
peaks or falling to low points is at least 1 year, and it can be as many as 15or 20 years.
Seasonal variation: The third kind of change in time-series data is seasonal variation.As we might expect form the name, seasonal variation involves patterns of
change within a year that tend to be repeated from year to year. Forexample, a physician can expect a substantial increase in the number of
flu cases every winter and of poison ivy every summer. Because these are
regular patterns, they are useful in forecasting the future.

Irregular variation: Irregular variation is the fourth type of change in time-series
analysis. In many situations, the value of a variable may be completely unpredictable,
changing in a random manner. Irregular variations describe such movements. Theeffects of the Middle East conflict in 1973, the Iranian situation in 1979-1981,the
collapse of OPEC in l986, end the Iraqi situation in 1990 on gasoline prices in the
United States are examples of irregular variation.
Time-series variations: Thus far, we have referred to a time series exhibitingone or another of these four types of variation. In most instances, however, a time
series will contain several of these components. Thus, we can describe the overall
variation in a single time series in terms of these four different kinds of variation. In
the following sections, the four components and the ways in which we measure eachare examined.
Trend Analysis
Two methods of fitting a trend line: Of the four components of a time series, secular
represents the long-term direction of the series. One way to describe the trend componentis to fit a line visually to a set of points on a graph. Any given graph, however, is subjectto slightly different interpretations by different individuals. We can also fit a trend line by
the least squares. Here emphasis will be given on the method of least squares because
visually fitting a line to a time series is not a completely dependable process.
Reasons for Studying Trends
There arc three reasons why it is useful to study secular trends:
a. The study of secular trends allows us to describe a historical Pattern. There are
many instances when we can use a past trend to evaluate the success of a previouspolicy. For example, a university may evaluate the effectiveness of a recruiting
program by examining its past enrollment trends.
b. Studying secular trends permits us to project past patterns, or trends, into thefuture. Knowledge of the past can tell us a great deal about the future. Examining the
growth rate of the worlds population, for example, can help us estimate the
population for some future time.c.In many situations, studying the secular trend of a time series allows us to
eliminate the trend component from the series. This makes it easier for us to study
the other three components of the time series. If we want to determine the seasonal
variation in ski sales, for example, eliminating the trend component gives us a moreaccurate idea of the seasonal component.
Trend Lines Take Different Forms:Trends can be linear or curvilinear. Before we examine the linear, or straight-line,
method of describing trends, we should remember that some relationships do not take that
form. A common example of a curvilinear relationship is the life cycle of a new businessproduct. When a new product is introduced, its sales volume is low. As the product gains
recognition and success, unit sales grow at an increasingly rapid rate. After the product is
firmly established, its unit sales grow at a stable rate. Finally, as the product reaches the
end of its life cycle, unit sales begin to decrease.

Trend by the Least-Squares MethodBesides trends that can be described by a curved line, there are others that are describedby a straight line. These are called linear trends. Before developing theequation foralineartrend, it is necessary to review the general equation for estimating a straight line .
Equation for estimating a straight line Y =a + bXWhere Y estimated value of the dependent variable
X = independent variable (Time in trend analysis) a = Y-intercept (the value of Y when X=0) b = slopeofthe trend line
Finding the Best-fitting Trend Line : We can describe the general trendof many time series using a straight line. But we are faced with the
problem of finding the best-fitting line. we can use the least-squares
method to calculate the best-fitting line, or equation. In this method Best-fitting Trend Line is determined as follows:
Slope of the Best-Fitting Regression Line,b=(XY-nXY)/(X2-nX2)
Y-Intercept of the Best-Fitting Regression Line
a=Y- bxwhere,
Y=values of the dependent variable
X= values of the independent variable
Y= mean of the values of the dependent variable X= mean of the values of the independent variable
n = number of data points in the time series
a = Y-intercept b = slope
Use of a Second-Degree Trend in a Time Series :Handling time series that are described by curvesSo far, we have described the method of fitting a straight line to a time series. But many
time series are best described by curves, not straight lines. In these instances, thelinear trend model does not adequately describe the change in the variable as timechanges. To overcome this problem, we often use a parabolic curve, which is describedmathematicallyby a second-degree equation.The general form for an estimated Second-degree equation is:
Y=a+b.x+cx2 100
Where, Y= estimate of the dependent variable a, b, and c = numerical constants
x = Coded values of the time variable
Finding the values for a, b, and c: again we use the least-squares method to determine the
second-degree equation to describe the best fit.
However, we can determine the value ofthe numerical constants (a, b. arid C) from

the following three equations:
Least-squares coefficient for a Second degree Trend
Y=an+cx2.ix2Y=a+cx4 ii
b=xY/x2.iii
When we find the values of a, b, and c by solving Equations i, ii and iii and si-multaneously, we substitute these values intothe second-degree equation, Equation 100.
As in describing a linear relationship, we transform the independent variable, time (X),
into a coded form (x) to simplify the calculation.
Time-Series Analysis in ForecastingWe have already examined all four components of a time series.We have described the
process of projecting past trend and seasonal variation into the future, while taking intoconsideration the inherent inaccuracies of this analysis. In addition, we noted thatalthough the irregular and cyclical components do affect the future, they are erratic and
difficult to use in forecasting.
Limitations of Time-Series analysis: We must realize that the mechanical approach of
time-series analysis is subject to considerable error and change. It is necessary formanagement to combine these simple procedures with knowledge of other factors, inorder to develop workable forecasts, Analysts arc constantly revising, updating. and
discarding their forecasts. If we wish to cope successfully with the future we must do thesame. When using the procedures of Time Series analysis, we should pay particularattention to two problems:
1. In forecasting, we project past trend and seasonal variation into the future. We mustask, How regular and lasting were the past trends? What are the chances that these
patterns are changing?
2. How accurate are the historical data we use in time series analysis? If a company haschanged from a FIFO (first-in, first out) to a LIFO (last-in, first-out) inventory
accounting system in a period during the time underconsideration, the data (such asquarterly profits) before and after the change are not comparable and not very useful forforecasting.

CHAPTER 06FINDINGS AND ANALYSIS OF THE STUDY.CONCLUSION AND POLICY
IMPLICATION
6.1. FINDINGS:Present recoverable gas reserve of Bangladesh is 13.952(as
of November/2005) TCF. It is worth mentioning that in US unit 1(one) TCF =1000000000000 cubic feet. So this gas reserve stands to 13.952x1000000000000 cubic
feet. Using time series analysis ( by means of Least Square Method of curve fitting ofmodel Y= a +bx t model) we find that total forecasted gas demand for 15(fifteen) years
in various category of gas use within Titas Gas T & D franchise area is 7839530.124
million cubic feet (MMCF), which is 56.189% of the entire gas reserve. This indicatesthat the remaining reserve will cater to the growing gas demand within Titas Franchise
area for than 15(fifteen) years. It may be up to approximately 30(thirty) years. This also
indicates that production of gas is to be enhanced to the extent of 40.92%. Using time
series analysis ( by means of Least Square method of curve fitting of model Y= a +bxt +cxt2 model) we find that total forecasted gas demand for 15(fifteen) years in various
category of gas use within Titas Gas T & D franchise area is 23424129.83 million cubic
feet(MMCF) which is 167% of the entire gas reserve. This also indicates that the
production of gas is to be increased at an average rate of 262.135%.
System loss is measured as the percentage of the difference between gas purchase and gassales. Mention-worthy that for 1% of system loss the company incurs revenue loss of
Tk.2 crore per month i.e. 24 crore per year. Employing time series analysis ( by means of
Least Square method of curve fitting of model Y= a +bx t model) we find that forecastedsystem loss would be arrested from 7.03%(December/2006) to 4.54%(December/2015),
preventing revenue of about 2 crore per month. Using time series analysis ( by means of
Least Square method of curve fitting of model Y= a +bx t + cx t 2 model), we find that
forecasted system loss would be enhanced from 7.03%(December/2006) to 21.59%(December/2015), enhancing revenue loss of about 0.0945 crore per month.

CHAPTER 07
CONCLUSION AND POLICY IMPLICATION
According to our findings there might be a significant gap between forecasted
gas demand and our production capacity, it is imperative to explore and discovermore gas resources so that more recoverable gas reserve is added to the remaining
reserve. Production of gas is to be enhanced. This would not be enough. The
government of Bangladesh should employ more resources in research andexploration of natural gas. The government of Bangladesh should promote
adequate skills and expertise among the personnel employed in the entire gas
sector to ensure efficiency and farsightedness in the management of the gassector. All-out endeavors should be undertaken to combat system loss by all the
people concerned, chalking out appropriate plans and course of action. As this
fossil fuel is not endless, there should be vigorous research for non-renewablesource of energy.
