The KrisEnergy-operated Wassana oil field in the Gulf of Thailand commenced production from the first development well of the G10/48 block.
Production is expected to reach approximately 10,000 bo/d by year end, KrisEnergy said, as the Key Gibraltar jackup rig, owned by Shelf Drilling Ltd., continues to drill additional development wells.
According to the Singapore-based firm’s director of exploration and production, Chris Gibson-Robinson, Wassana is KrisEnergy’s first operated oil project and the start of production marks a major milestone for the company.
“Work is now underway to bring another five wells on stream and to optimize production in this initial wave of drilling,” Gibson-Robinson said. “This field is the first of a series of KrisEnergy-operated developments we are working on in Thailand, Cambodia and Indonesia.”
Up to 15 development wells are planned, 14 producer wells and one water disposal well. The Wassana infrastructure comprises a mobile offshore production unit (MOPU), the MOPU Ingenium, a mooring buoy and the Rubicon Vantage floating storage offloading vessel.
Covering 4696sq km over the Southern Pattani basin in water depths of up to 60m, the G10/48 contract area contains three other discoveries, such as Niramai and Mayura from 2009 and Rayrai in 2015.
KrisEnergy holds 89% working interest in G10/48 and Thailand’s Palang Sophon Offshore holds 11% working interest.
KrisEnergy and Palang are also joint venture partners of G11/48 in the Nong Yao field offshore Thailand. Operated by Mubadala Petroleum, the Nong Yao field commenced first production in June.
Furthermore, KrisEnergy has also submitted a plan of development for the Rossukon oil field in Thailand, plus operates Block A in Cambodian waters, where it is seeking to develop the Apsara oil field.
