BONGKOT
CELEBRATING
20 YEARS
ENERGISING THAILAND

BONGKOTGAS FIELD
History
July 15, 1993 marked the birth of Bongkot and a turning point in the energy scene of
Thailand where most people never imaged possessing rich gas reserves.
Bongkot, or lotus in Thai, arose against the backdrop of a country that once was
entirely dependent on imported petroleum resources for its energy needs.
The coming on-stream of Bongkot on the day ushered in a new era for partial energy
suffi ciency and national economic development by opening up a string of industrial projects which
captured added-values originated from the gas.
Twenty years on, the Kingdom’s largest gas fi eld, lying about 600 km south of Bangkok in
the Gulf of Thailand, has unwaveringly maintained its role as an energy lifeline and an enabler of
progress for Thailand.
Bongkot, part of the 4,231-square-kilometre Navamindra Petroleum Area, has contributed
signifi cantly to the Eastern Seaboard Development Project on the Thai eastern coast which gave
a dramatic impetus in industrialisation.
An outstanding track record achieved by Bongkot over the past two decades provides a good
reason to celebrate and commemorate Bongkot’s 20th anniversary.
• Cumulative Bongkot gas production reached 3.66 trillion cubic feet (Tcf) plus 106 million
barrels of condensate, translated into 700 million barrels of crude oil equivalent.
• The current gas output of over 870 million cubic feet per day (MMcfd), excluding about 30,000
barrels per day (b/d) of condensate produced in association with the gas, meets about 20%
of Thailand’s overall daily natural gas consumption, or accounting for around 30% of the
combined indigenous gas output.
• Bongkot has been one of the main contributors of gas supplies which together generate 70%
of electricity that Thailand consumes.
• Recording a 99.5% reliability factor, meaning any disruption to gas delivery is extremely rare.
• Operating in an environmentally friendly and utmost safe manner.
• Valuable gaseous components extracted from raw natural gas stream from Bongkot are
turned into to liquefi ed petroleum gas (LPG) and vital feedstocks for petrochemical, an
industry that arose partly out of Bongkot discovery.
• Contributing over 240 billion baht to the national coffers in the forms of royalty, taxes and
government sharing over the 20-year span.
• A major job creation with thousands of people employed directly and indirectly down the value
chains stemming largely from Bongkot.
Today, 15 July 2013, also represents a special moment for the country in general and PTTEP
in particular as it underlines the 15th year of successful running of Bongkot by a Thai outfi t —
PTTEP.
The celebration will go on for another decade as the Bongkot consortium strives to sustain its
key role in providing affordable, reliable and clean energy for Thailand.
The success story of Bongkot dated back to May 1973 when
the US oil fi rm Tenneco struck oil and gas at the wildcat 15-
B-1X in block B15, lying in the Malay Basin.
Although not originally perceived to be large, later
drilling by the UK-based BP Petroleum and Texas Pacifi c
International Inc of the US in the area confi rmed the presence
of a gas bonanza.
Texas Pacifi c, which took over the interests of B15 and
its adjacent tracts B16 and 17 in 1978, drilled 23 wells to
confi rm the rich gas deposits at the intensely faulted field
which was known as the “B” structure.
Realising the vast long-term benefi ts of “B” Structure
gas to national development, the Thai government made
a landmark decision to acquire the concession rights from
Texas Pacifi c in 1988.
At the same time, PTTEP, which was incorporated in
June 1985, was entrusted by the government to assume
the concession rights and leading the development towards
tapping benefi ts thus derived.
In 1990, PTTEP took three major global oil companies,
namely Total of France, British Gas and Norway’s Statoil, on
board as partners in the ‘’B’’ Structure which was renamed
as Bongkot. Statoil withdrew its interest in Bongkot project in
1998 as part of its realigned business strategy.
Total was initially entrusted as the operator of Bongkot
for the first fi ve years of production with an agreement to
transfer the controls of operation to PTTEP by mid-1998.
That agreement was triggered by the government’s
foresight to use Bongkot as a platform to develop a local
capability to manage, hands-on, a sophisticated capital and
technological intensive industry which is all important to the
kingdom.
Indeed, PTTEP has become what it is — a world-class
energy company with more than 40 upstream interests across
12 countries, due to its fruitful engagement in Bongkot.
“Bongkot is like a prestigious university which provides
real-life practical lessons and rich experience for us at
PTTEP”, said Nawee Anantraksakul, PTTEP senior vice
president for Bongkot Asset.
PTTEP’s growth may not be as impressive as it has
been without an active involvement in Bongkot, he pointed
out, referring especially to human resource capability.

Pragmatic approach
Development of Bongkot was successful carried out over time
with a pragmatic approach in four stages with a view to increase
deliverability in a maximum sustainable manner.
Phase I: Initial endeavour zeroed in on bringing the
fi eld on stream at the rate of 150 MMcfd in July 1993 and
subsequently raising the fl ow rate to 250 MMcfd.
Supporting that plan was an offshore production
facility which included the three well-head platforms, one
production platform, one living quarter platform and a
condensate tanker with 200,000-barrel capacity.
Phase II: A second offshore complex was put into place
and 48 additional production wells were sunk to enable
Bongkot to boost gas output to 350 MMcfd in April 1996.
The extended facilities consisted of fi ve well-head
platforms, a riser platform and a fl are structure.
Phase III: In July 1998, Bongkot began to ramp up the
gas fl ow rate further to 550 MMcfd along with 22,000
b/d condensate which were made possible by additional
offshore facilities.
They included 12 well-head platforms, a new sour
process platform, additional facilities installed on the central
complex, and a 400,000 barrel-capacity fl oating storage
and offl oading vessel (FSO), named Pathumabaha by HRH
Princess Maha Chakri Sirindhorn, to replace the old FSO.
Phase IV: This development was geared towards
incorporating productive areas within the concession
including South Bongkot, Ton Koon and Ton Nok Yoong
structures into the mainstream Bongkot production with an
incremental delivery of 320 MMcfd in 2012.
Being instrumental to this development phase, collectively
known as Bongkot South, was a set of offshore facilities
including one production platform, one living quarters
platform, 13 well-head platforms and an 8-inch 82-km
condensate pipeline linking Bongkot South production
platform to the Pathumabaha vessel.
Challenges
While Bongkot’s performance has been highly impressive beyond original expectation by yielding
3.66 trillion cubic feet (Tcf) and 106 million barrels of condensate to date, huge challenges remain
to keep the fi eld fl owing over the next ten years.
It will be more diffi cult and costly to obtain new gas which will tend to be marginal, deeper and
remote away from Bongkot central facilities.
That will require PTTEP and its partners to continue to work strenuously and invest heavily,
to the tune of US$5 billion over the next fi ve years, to recover some 300 million barrels of oil
equivalent in proved gas and condensate reserves remaining at Bongkot.
The scale of future development and expenditures are as impressive as what already put into
Bongkot over the past two decades but in a shorter period.
Some comparisons: Between 2013 and 2017, 400 development and 40 exploration wells
were planned.
Over the past two decades, a total of 73 exploration and appraisal wells plus 416 development
wells were bored at Bongkot with a combined investment cost soaring to $6.6 billion.
“If we did not continue to work hard and integrating all kinds of technology into our endeavour,
we would see a steep and fast decline in production from Bongkot,’’ Mr. Nawee pointed out.
“The mission to find reserves replacement is the order of the day at PTTEP as the known
deposits are drained everyday too.’’
Despite the prohibitive cost investment for the next stage of development at Bongkot, PTTEP
and its partners are preoccupied with searching ways and means to be more cost-effective and
recovering as much as hydrocarbons in the most effi cient and environmental-friendly manner, he
added.
PTTEP sees the possibilities of Bongkot fl owing even after the end of concession in 2022-
23, albeit at a lower rate, pending government approval for concession extension and further
exploration.
Eco-friendly
Eco-friendliness is one the cardinal operating words at Bongkot whose environment, both in the
air and water, is well protected by a series of technological-driven measures and determination.
The discharge of muddy water produced in the process of drilling into the sea is zero as such
liquid is re-injected back into the disposal wells at the depth of between 1,000-2,000 metres where
it is safely contained.
A facility has also been put in place to recover part of the gas from the offshore processing
process, which would otherwise be totally burned at fl are stacks for safety reason, for good use.
The fl are recovery unit allows PTTEP to capture more than half of 8-9 MMcfd of gas which
was normally directed to the fl are stacks at Bongkot and turned into useful condensate. A second
unit will be installed offshore in 2014 as Bongkot joint venture strives to optimise the benefi ts of the
fi eld’s resource as well as further reducing emission in its atmospheric environment.
Membrane technology has also been effectively applied at Bongkot South to remove carbon
dioxide, mercury and hydrogen sulphide from natural gas.
Through that process, natural gas becomes purer and can be cleanly burned, thus contributing
to better air quality.
The history of Bongkot’s environmental responsibility goes back to its day-one and to its
operations being ISO 14001 Environmental Management System certifi ed in December 2001.
Since then it has been continuously re-certifi ed.
Bongkot is also where PTTEP’s core value — SSHE (safety, security, health and environment)
- has been vigorously practiced.
While operating in hazardous environment with infl ammable substance, years of
monitoring show that Bongkot fi eld is one of the safest place to work.

REFLECTIONS OF
20-YEAR SUCCESSFUL PRODUCTION
How important is the overall Bongkot project to Thailand in terms of petroleum
imports substitution and other value chains it helps to spur
From the perspective of the country, Bongkot has been a vital indigenous source
of energy supply, substituting petroleum imports, lessening dependence on imported
energy while creating an extensive value chain for the Thai economy.
Bongkot has been Thailand’s largest gas fi eld. Its current gas output of over 870
million cubic feet per day (MMcfd), excluding about 30,000 barrels per day (b/d) of
condensate produced in association with the gas, is equivalent to about 20% of the
Kingdom’s overall gas consumption which stands at around 4,500 MMcfd.
Bongkot gas also represents around 30% of the Kingdom’s combined indigenous
natural gas production.
Its present gas production level can fuel six generators the size of Khanom
power plant (818 megawatt capacity), one of the main sources of electricity supplies
for southern Thailand and which is located in Nakhon Si Thamarat.
Propane and Butane extracted Bongkot gas have also been turned into LPG
(liquefi ed petroleum gas) which are widely used as household, vehicular and industrial
fuel, as well as raw material for petrochemical industries.
Over the past two decades, Bongkot has contributed over 200 billion baht in the
form of royalty and tax payment to the national coffer.
Bongkot is a major job creation, directly employing about 600, 200 of them are
PTTEP staff and 400 are personnel of contractors.
The size of people employed indirectly by contractors who provide supporting
services for the offshore gas operation, those who engage in petrochemical industries
and other downstream activities are hard to quantify, but it is absolutely in great
numbers.
What does the Bongkot development mean to PTTEP
From PTTEP’s viewpoint, our remarkable evolution over the past 28 years, from
a tiny offshoot of the then Petroleum Authority of Thailand (PTT) to an outfit with
world-class status, stemmed from our fruitful engagement in the Bongkot JV for more
than 20 years.
Here at the Bongkot, PTTEP has developed the capability, expertise, confi dence
and reputation in operating a geologically complex and the substantial hydrocarbon
saccumulation offshore.
Bongkot is like an institution to PTTEP, a place where we have learned, handon,
practical knowledge about running a giant gas fi eld professionally, effi ciently,
smoothly and safely.
The apprentice began in 1990 when Total was tasked to operate Bongkot on
behalf of the joint venture group and in that process helped grooming key PTTEP
personnel for seamlessly taking over the fi eld’s operatorship eight years later.
Gas production began in 1993, and by 1998, PTTEP was ready for such a big
act, amid certain scepticisms that a Thai outfi t would really
be able to accomplish that
task.
But from that time onward, PTTEP has proved
sceptics wrong and successfully been operating Bongkot
whose operation has grown
by leaps and bounds with
daily gas fl ow leaping fi ve folds between then and now.
Further we have a
rewarding and mutually
benefi cial relationship with our JV partners, Total E&P
Thailand and BG Asia Pacifi
c Pte. Ltd., strengthened
over 23 years of successful collaboration.
What are the lessons learned prior to and
after PTTEP’s assuming the operatorship
of Bongkot
Most senior members of PTTEP’s
current management team have passed
through a good learning curve embedded
in the Bongkot operatorship transfer
process in one way or another.
I myself engaged in fi nalizing Bongkot gas contract with PTT, fi nding joint venture
partners, looking at reservoirs and mapping out fi eld development plan in the initial stage.
Our previous operator, Total, has had a truly industry’s best practice, being it
in safety procedure, operating standards, philosophy and culture which altogether
provides an excellent basis from which PTTEP can build its own procedural platform,
corporate culture and safety regimes.
With profound knowledge and practical skill derived from running Bongkot,
PTTEP has naturally become fully confi dent in the pursuit of new interests both at
home and overseas.
Our experience at Bongkot serves as a superb reference when we seek ventures
abroad as the sense of confi dence in us permeates across all parties concerned –
right from our own board of directors, to joint venture partners and countries in which
we seek a presence.
Without the capability and expertise gained from active participation in Bongkot,
as well as the onshore S1 oil producing concession (Sirikit oil fi eld in Kamphaeng
Phet, Pitsanulok and Sukhothai) to some extent, PTTEP will not have the leverage to
grow so robustly to become what it is today.
Arthit, the sibling of Bongkot, is a good showcase which the Bongkot experience
was effectively applied by several members transferred from Bongkot.
At Arthit, they have engaged in the entire spectrum of activities necessary
in actually putting a fi eld on stream - right from exploration to development and
production.
Furthermore, the Bongkot experience has found good application at the Zawtika,
one of the major gas deposits lying in Myanmar’s Gulf of Martaban and whose
development is entirely being carried out by PTTEP.
We can duly claim that our insightfulness about the Gulf of Thailand’s subsurface
character is second to none, thankfully to our Bongkot experience.
What is the scale of cumulative investment and works put into the Bongkot over
the past two decades
Undoubtedly it is indeed sizable. Including the shares of our joint venture
partners, the cumulative combined capital and operating expenditures so far soared
to US$6.6 billion with $3.3 billion being PTTEP’s portion.
To date, a total of 73 exploration and appraisal wells plus 416 development wells
were bored at Bongkot.
The production has been supported by 33 well-head platforms, three processing
platforms, two living quarter platforms, two fl are structures and a floating condensate
storage tanker.
Aggregate cumulative gas production, from North and South Bongkot fi elds, is
3.66 trillion cubic feet (Tcf) and 106 million barrels of condensate, together being
translated into 700 million barrels of crude oil equivalent.
Since Bongkot has been in production for two decades now, does it show that
the field is more prolific beyond the original expectation
Given what Bongkot has already yielded so far, it is absolutely right to say that
the fi eld has performed far better than what we saw back in early1990s when PTTEP
took over the ownership of what was known as “B Structure” from Texas Pacifi c, the
former concessionaire from the United States.
At that time, we reckoned there would be 1.5 Tcf in proved gas reserves, or up to
2 Tcf in a bestcase scenario, to work with.
But as time went by with better knowledge, greater expertise, technological
advancement, Bongkot gas fl ow rate has consistently on the way up, from 150 MMcfd
to 250 MMcfd in the initial phase, and been 350 MMcfd to 550 MMcfd in intermediate
stage, before reaching the current plateau level of approximately 900 MMcfd.
Proving more reserves and raising gas delivery has been a big challenge due to
the complexity of geological condition which requires PTTEP to penetrate many more
small pockets of gas deposits in a wider spread of the offshore areas.
However, We are fortunate that an average well at Bongkot yields about 10 billion
cubic feet, twice as much as an average producing well lying in the upper part of the
Gulf of Thailand.
“Bongkot has been Thailand’s largest gas field. Its current gas output of over 870
million cubic feet per day (MMcfd), excluding about 30,000 barrels per day (b/d) of
condensate produced in association with the gas, is equivalent to about 20% of
the Kingdom’s overall gas consumption which stands at around 4,500 MMcfd.
Bongkot gas also represents around 30% of the Kingdom’s combined
indigenous natural gas production.”
Tevin Vongvanich, PTTEP President and CEO, speaks candidly about the evolution,
vision and
dedication involving Bongkot as an energy lifeline for Thailand.

However, it is much more diffi cult to recover the gas from Bongkot or elsewhere
in the Gulf of Thailand when compared to, say, the productive gas fi elds offshore
Myanmar where hydrocarbons deposits are more concentrating and larger in size
within a more expansive reservoir.
To be able to produce 600 MMcfd of gas at North Bongkot, we need 300 wells,
compared to merely lowerthan 20 wells required to drain a similar fl ow rate from
Yadana fi eld, Gulf of Martaban.
How long will Bongkot be able to sustain the current flow rate
There are about 300 million barrels of oil equivalent in proved gas and condensate
reserves left at Bongkot, meaning that if we continued at the present production level,
those reserves would be depleted over the next 4-5 years.
However, there still are probable and possible reserves, as well as ‘resource’
potential, at Bongkot and the nearby area which could potentially be recovered,
pending further investment by the JV exploration and evaluation.
In the possible category, the discovery certainty is at 50% and 20% for the
probable.
All in all, we are fairly confi dent to be able to sustain the current delivery rate of
over 900 MMcfd for another ten years or until 2022-23 when the concession granted
by the government ends.
It is our intention to keep Bongkot on stream after 2022-23 and we believe that
there are some resources lying there awaiting to be tapped for the benefi ts of our
country if the Government allows the extension of the concession.
What are the challenges PTTEP is facing to sustain Bongkot production
With 20 years in production, Bongkot is like a middle-aged person who needs to
care for himself.
That is why, in the fi rst place, we have to ensure that our offshore facilities are in
tip-top working condition through proper maintenance.
Secondly, we have to drill more wells to replace those whose production has
depleted.
Thirdly, we have to move into areas where gas was found but were not
commercially viable to develop because of their small deposits.
That is a huge challenge to recover gas from these marginal gas accumulation in
the sense that we have to find most economical methods to do so.
Fourthly, we have to expand our reach to locations where no exploration wells
were previously drilled but possessing discovery potential.
Furthermore, we will have to drill deeper wells, which are greater than 3 kilometres
for an average Bongkot well.
These deep wells present much more challenging not only from greater diffi culties
involving depths but there are issues about high pressure and temperature, of more
than 200 degree Celsius, in the borehole, as well as prohibitive costs.
What is the scale of works and investment required to enable Bongkot to remain
active in production
Over the next fi ve years (2013-2017), PTTEP and partners together would need
to spend about $5 billion in capital and operating expenditures to sustain Bongkot
production.
We target to bore 40 exploration and appraisal wells in the period. We also need
to drill up to 400 development wells to collect all those small gas pockets.
Those numbers are signifi cant as compared to what we have undertaken in the
longer span of time, of over 20 years, at Bongkot.
Part of the planned capital outlay will go towards installing more well platforms
to accommodate those new development wells which more diffi cult and costly to drill.
It is essential for us to continue to work hard and capitalising in on the advanced
technology, such as the so-called ‘’slim-hole’ drilling technique, and long-established
experience and knowledge, to prolong Bongkot’s longevity in the most cost effective
way possible.
If you could go back in time, what should have been done regarding the Bongkot
project
If we knew the fi eld’s reserves could be this large and spreading out like this, we
could come up with better overall development planning such as in terms of optimising
platforms design and locations as well as preparing larger manpower base.
Moreover, we should have been more active in sharing the Bongkot’s success
story and diffi culties involved so that members of the public were better aware of the
importance of an energy resource and use it effi ciently.
But after all, the truth was that we did not have the luxury of such knowledge then
and we did what we saw fi t.
Our step-by-step approach in ramping up gas delivery smoothly over the period,
from 150 MMcfd to over 900MMcfd, is a good indication that we have been on the
right track.
Thai Energy Ministry officials have been saying that Thailand will run out of
indigenous oil and gas in the next ten years and the chance of new discoveries
is slim. What is PTTEP’s view on that
What they have been saying is the country’s remaining known gas reserves
would dry up over that period based on the current fl ow rates and assumption of no
new discoveries are made.
However, I believe there are still chances for fi nding more reserves if exploration
and production companies were allowed by the government and communities to do
their jobs well.
New petroleum concession blocks should be made available to support the
hunt for possible new reserves in locations where little or no exploration has been
undertaken.
Of course, the chance of fi nding gas deposits the size of Bongkot in the Gulf of
Thailand is probably like winning the fi rst lottery prize.
However there are shining opportunities for gas reserves –in the offshore
Thailand-Cambodia’s Overlapping Claims Area (OCA).
The 26,000 sq km tracts share subsurface geological structure similar to
productive areas on the Thai waters.
Since no exploration has been undertaken, the magnitude of gas deposits is still
unknown.
Unfortunately, I think it may take a long while before the governments of Thailand
and Cambodia can settle their differences that will allow activities to start.
PTTEP has played a key role in providing hydrocarbons to meet a good part of
Thailand’s energy need. Will that role continue well into the future even if all
local reserves were gone How does PTTEP go about ensuring energy supplies
for Thailand
The mission of meeting Thailand’s energy demand entrusted to us and parent
PTT Plc by the Government remains unabatedly at the forefront.
That means to say our top priority is maximising local petroleum production,
searching for more reserves and sustaining optimum output.
As Thailand’s energy grows and indigenous hydrocarbon production looks set
for dwindling, PTTEP has, at the same time, sought resources from overseas.
Today, PTTEP has extended our engagement in the upstream industry in places
like Australia, Africa, Middle East, North America, on top of Southeast Asia especially
Myanmar.
These overseas provide possible direct access to energy supplies which can
either be directed to Thailand or being disposed locally there to generate income for
PTTEP.
We are especially keen to engage in gas development projects which have
the potential to be turned into liquefi ed natural gas (LNG) which will fulfi l Thailand’s
demand.
But the opening of Myanmar and its energy demand ensures that we cannot
signifi cantly increase our natural gas imports more than we received from Yadana and
Yetagun gas fi elds in Mayanmar’s Gulf of Martabun today. Therefore, we are on the
lookout virtually on almost all countries surrounding Thailand, particularly Indonesia,
for supplies which are more easily accessible.
Over the long term, we see shale oil and shale gas as likely additions to our
portfolio. We are taking a good look at these new energy forms and if there is suitable
opportunity emerging we may consider taking it on board.
PTTEP has pursued a path of being a global player in resource development.
How does it strike a good balance between meeting Thailand’s energy needs
and playing an international role
When you compare PTTEP with multi-national major oil concerns like ExxonMobil
and Royal Dutch/Shell, theirs are more than 20 times the size of ours.
By that comparison, ours falls into the ‘S’ (small) category when measured in
terms of investment, reserves and production scales.
But it is gratifying to say that our capability, dynamism and growth potential are
nothing to shy about in the international standards, and we are capable of competing
well with other industry players when it come to the issues of resource development.
We are a national oil company which seeks overseas interests to consolidate
our resource base largely to build on security of energy supplies for Thailand while
providing growth for the fi rm itself.
We are committed to be a major player at home and expanding an international
role with the purpose of serving the best interest of Thailand.
