KrisEnergy Ltd., an independent upstream oil and gas company, has approved the final investment decision for the development of the Wassana oil field in the Gulf of Thailand G10/48 license, where production is anticipated to begin in the second half of 2015.
The Wassana development concept comprises a mobile offshore production unit (MOPU) and 12–14 development wells producing to a floating storage offloading vessel. The company has secured the use of a converted Bethlehem Matt Type jackup rig currently employed as an MOPU offshore Malaysia. The unit is suitable for water depths up to 65 meters and has full hydrocarbon processing facility for up to 20,000 barrels of oil per day (bopd) and a water injection capacity of 15,000 barrels per day. KrisEnergy will take delivery of the MOPU in September when it will go into drydock for inspection and minor refurbishments.
KrisEnergy holds 100% working interest in G10/48, which covers 4,696 square kilometers over the southern section of the Pattani Basin in water depths up to 60 meters. The license contains three oil discoveries – Wassana, Niramai, and Mayura – in various stages of development or appraisal. The Wassana oil field is expected to reach a peak production of 10,000 bopd.
Chris Gibson-Robinson, director of exploration and production, said, “Having taken over operatorship of G10/48 in mid-May, we are making good headway in advancing the Wassana development. The MOPU solution is efficient both in timing and costs, but it also provides the flexibility to look at future commercialization of other discoveries in the G10/48 license area. We have also mapped a portfolio of prospects and leads in this block, some of which will provide additional development areas once we have completed further exploration drilling.”
