Singapore: KrisEnergy has said that drilling of the Rossukon-2 exploration well at the G6/48 block, located in the Gulf of Thailand, has so far proven to be a success.
Drilling began last week utilising the Key Gibraltar jackup rig, and preliminary well logs indicate that the well intersected approximately 69 feet true vertical depth of net oil-bearing sandstones and 37 feet true vertical depth of net gas-bearing sandstones, over five reservoir intervals.
The logging program is expected to be completed by tomorrow, at which point Rossukon-2 will be plugged back and the Rossukon-2ST directional sidetrack well will commence drilling out approximately 1.3 km to the northwest.
“The results from Rossukon-2 provide an encouraging basis to drill a sidetrack well to further define the lateral extent of the hydrocarbon columns and explore for new zones. These wells, together with the original 2009 discovery well, will bring us a step closer to deciding commerciality of the accumulation and the potential development concept,” said Chris Gibson-Robinson, KrisEnergy director exploration & production.
The G6/48 block covers 566 sq km and lies to the north of G10/48, where the Wassana oil field is being developed. KrisEnergy holds a 30% working interest in the concession and is partnered by Northern Gulf Petroleum and Mubadala Petroleum.
