Key Data

Project Type Gas and condensate development

Location Gulf of Martaban, Burma (Myanmar)

First Production 2013

Reserves Two trillion cubic feet

Operator PTT Exploration and Production (PTTEP) International

Partners PTTEP International (80%) and Myanma Oil and Gas Enterprise (20%)

Contractors Larsen & Toubro Valdel Engineering, SMOE and China Petroleum Pipeline Bureau

Zawtika project includes the development of the Zawtika, Kakonna and Gawthaka fields, located in blocks M9 and M11

of the Gulf of Martaban, offshore of Myanmar. The project is spread across an area of 11,746 square kilometres.

Petroleum Authority of Thailand Exploration and Production International (PTTEP International) is the operator of the

project. PTTEP owns an80% interest in the project, with Myanma Oil and Gas Enterprise (MOGE) holding the remaining

20%.

The $2bn project is expected to come on-stream in 2013. Initial output from the field is estimated at being 300 million

metric cubic feet a day (MMcfd).

Myanmar is estimated to contain 3.2 billion barrels of oil and 18 trillion cubic feet (tcf) of natural gas reserves. Nearly a

quarter of this production is sent to Thailand. Output from the Zawtika field will also be sent to Thailand, increasing its

imports to between 1.2 and 1.3 billion cubic feet each day.

Discovery and geology of Myanmar's fields

"Petroleum Authority of Thailand Exploration and Production International

(PTTEP International) is the operator of the project."

All the three fields of the project were discovered in 2007. Zawtika was discovered by the Zawtika-1 well in 2007. It hit

seven significant gas reservoirs and accumulations.

Gawthaka was discovered by Gawthaka-1 well, which was drilled to a depth of 3,380m and flowed at the rate of

9.4MMcfd.

Drilling of the Kakonna-1 well led to the discovery of the Kakonna field. The well indicated a link between the northern

and southern parts of Block M9. It flowed at the rate of about 21.2MMcfd and 8.6MMcfd during two tests.

The Zawtika project fields are biogenic gas formations consisting of reservoirs of Miocene-Pliocene Delta Front

sandstones, located at a depth of 750m to 1,580m, and shallower reservoirs in the Pleistocene strata at depths of 500m.

The project is estimated to contain nearly two trillion cubic feet (tcf) of gas.

Drilling and appraisal of the Burmese gas fields

PTTEP drilled seven exploration wells in Block M9 in 2007 after the discovery of the Zawtika field. These were Zawtika-

1, Gawthaka-1, Kakonna-1, Zawtika-2, Zawtika-3, Zawtika-4 and Zawtika-5.

"Myanmar is estimated to contain 3.2 billion barrels of oil and 18 trillion cubic

feet (tcf) of natural gas reserves."

Zawtika-2 well, located in the southern part of Block M9, was drilled to a depth of 3,500m. It encountered significant

quantities of natural gas in six zones and flowed at the rate of 109.5 million standard cubic feet a day.

Zawtika-3 was drilled to a depth of 2,274m and encountered hydrocarbons in eight zones. It flowed at the rate of

26.7MMcfd. Zawtika-4 flowed at the rate of 71.1MMcfd from two zones. It was drilled in May 2007 to a depth of 2,390m.

Zawtika-5 encountered seven natural gas zones and flowed at the rate of 38.36MMcfd. In 2010, PTTEP drilled two

appraisal and one exploration wells.

Zwatika developments

PTTEP submitted the field development plan for the project to MOGE in the last quarter of 2011. The plan was approved

in February 2011. Detailed engineering and construction work for the project is currently ongoing.

The project is planned to be developed in phases. The first phase of the project is being implemented currently. It includes

the installation of three wellhead platforms, an integrated processing and living quarters, and 21km of subsea pipelines

with 18in diameter.

Nearly 80% of the produced natural gas will be exported to Thailand through a 28in diameter, 300km long pipeline. About

270km of the pipeline will be laid offshore, while the remaining 30km will be onshore.

Infrastructure of PTTEP's project

The three wellhead platforms and jackets will weigh between 7,000t and 8,000t. They will be installed at a water depth of

130m to 150m.

The processing facility will include topsides weighing 15,000t. The jacket of the topsides will include 20,000t piles. The

processing facility will also include living quarters, with an accommodation capacity for 128 persons, and a 100m flare

boom. It will be a bridge connected to one of the wellhead platforms.

Environmental Impact Assessment (EIA) of Dawei Deep Seaport Port

Project

Client : Italian-Thai Development Public Company Limited

Administered by : TEAM Consulting Engineering and Management Co., Ltd.

Dawei is a port at the head of the Dawei River estuary. It is a city in the southeast of Myanmar and is the

capital of the Tanintharyi Region. After completion, Dawei will become one of Southeast Asia’s important

ports. It will link countries in the Indian Ocean, the Middle East, Europe, and Africa, without the need to

pass the Malacca Strait. It will have the capacity to handle over 100 metric tons of cargo annually. The

project comprises three phases: 1. construction of the public infrastructure; 2. construction of the deep

seaport; and 3. construction of the industrial estate.

TEAM Consulting Engineering and Management Co., Ltd. is engaged in the project for the environmental

impact study, the assessment for the project site and its environs, and the implementation of the EIA and

EMP reports.
