SINGAPORE – Average oil production last year from the Wassana field in the G10/48 concession in the Gulf of Thailand was 4,377 b/d, according to operator KrisEnergy.
In October, the facilities were shut down briefly to allow replacement of the produced water return line, a floating hose roughly 100 m (328 ft) long, between the CALM buoy and the floating storage and offloading vessel.
Production was then shut in for a further period in November for the arrival of thePV Drilling Ijackup, in preparation for a six-well infill drilling program.
Two infill horizontal wells, A-20H and A-22H, subsequently came onstream in December, lifting gross production to 5,875 b/d from 12 producing wells, and four further infill wells, A-18H, A-19H, A-23H and A-25H, were completed and brought online last month.
As a result, production should rise to around 7,000 b/d from 16 producing wells, once optimization measures are completed.
The company is a partner in the offshore Nong Yao oil field in G11/48 in the same region. Here six infill wells were drilled, with 22 wells producing at the end of 2017. Two additional infill wells are scheduled to go online by the end of this month, and four more will likely be drilled later this year.
