Our portfolio contains a balance of assets across the E&P life cycle
KrisEnergy's focus area runs from the Surma Basin in Bangladesh in the west to the Papuan Basin in the east, and from offshore southern China in the north to Indonesia in the south. Our activities include all facets of exploration, appraisal, development and production, from identifying potential prospects to discovery and commercialisation.
Our current portfolio comprises interests in three producing assets (B8/32 and G10/48 oil and gas fields in the Gulf of Thailand and the Bangora gas field in Block 9, onshore Bangladesh), two oil development projects (G6/48 in the Gulf of Thailand and Block A offshore Cambodia), one gas development in Indonesia (Bulu PSC offshore East Java), and five exploration/appraisal blocks in Bangladesh, Indonesia, Thailand and Vietnam. The B9A licence in the Gulf of Thailand ceased production in October 2017 and abandonment operations are underway before the area is relinquished.
Under the terms of the licences for the contract areas, the company holds various rights to explore for, develop and/or extract oil and gas resources in a specifically demarcated area under agreement with the respective governments or the regulatory bodies.
Each project is unique but will encompass a combination of key stages:
Pre-exploration
|
Our business development team will work up exploration concepts in areas where we have detailed knowledge. When a target area is identified, we will acquire and interpret existing data including seismic, other geophysical or geological data, and carry out geological fieldwork. If the results are positive, we will seek to acquire an exploration licence from either the host government or the entity holding the existing rights to the contract area. |
Exploration
|
On acquisition of an exploration licence, we will gather and interpret further data to plan an exploratory drilling program to assess potential reserves. At this stage, we may seek to mitigate risk and defray costs by farming out to third parties all or a portion of the exploration drilling costs. |
Development
|
Once an oil or gas discovery is made, we will acquire and interpret further information in order to formulate an appraisal drilling program to assess the outer parameters of the reserves and determine the economic viability of the discovery. If appraisal drilling is successful, we will employ an independent consulting firm to certify the reserves and that assessment will be used to prepare a plan of development. Once the plan is approved, we will drill development wells and construct the facilities required for production to commence. |
Production
|
Once production has commenced, we will maintain the field and make every attempt to extract oil or gas as efficiently as possible. This may include re-entry of wells to repair production equipment, the drilling of closely spaced wells and the close monitoring of reservoir/production performance. |

Oil production in Indonesia began in the 19th century and today almost 300 contract areas are under licence, nearly 80% of which are located in the mature, oil-producing western basins where infrastructure is well developed. Gas accounts for more than two-thirds of Indonesia's remaining hydrocarbon reserves and its commercialisation is increasingly important in the country's energy mix.
We operate three production sharing contracts (PSCs) - Bulu, Sakti and Udan Emas, one of which contains a gas discovery (Bulu in the East Java Basin).
Sakti forms gas

Offshore East Java
The Sakti PSC is an exploration block covering 3,719 sq km offshore East Java where water depths in the East Java Sea are between 50 and 60 metres. It is adjacent to the KrisEnergy-operated Bulu PSC.
An application was submitted to the Indonesian authorities in November 2019 to extend the Sakti PSC into the second phase exploration period for four years. The first exploration phase expired on 25 February 2020. Approval of the extension was granted by the Indonesian authorities, extending the PSC to 25 February 2024, and the gross acreage of the contract area was reduced to 989 sq. km.
KrisEnergy was awarded operatorship with a 95% working interest in the Sakti PSC in February 2014. The other partner is Golden Heaven Jaya Ltd. with 5%.
In 2014, we acquired 1,202 km of 2D and 401 sq km of 3D seismic data in the Sakti PSC. An exploration well was drilled in 2015, which encountered gas with a high level of carbon dioxide.

KrisEnergy is building a core area offshore Vietnam
There are more than 90 contract areas under licence in Vietnam, mostly located in the Nam Con Son Basin. KrisEnergy holds working interests in one exploration licence, Block 115/09 covering 7,382 sq km in the southern Song Hong Basin, offshore central Vietnam.
Although lightly explored with just over 224 exploration, appraisal and production wells drilled to date, the Song Hong Basin contains some 35 fields, predominantly gas, with expected ultimate reserve recoveries of approximately 14 trillion cubic feet of gas and 198 million barrels of oil and condensate*. The Phu Khanh Basin is less explored with only five exploration wells drilled to date. It is notable, however, that four of the wells were non-commercial oil or gas discoveries, indicating the attractiveness of the region.
