OPERATIONS - KrisEnergy 2020

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 six 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 four production sharing contracts (PSCs) - Bulu, Sakti, Bala-Balakang and Udan Emas, two of which contain gas discoveries (Bala-Balakang in the Makassar Strait and Bulu in the East Java Basin) and hold a non-operating working interest in the Andaman II PSC, offshore North Sumatra.

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.
