Singapore listed KrisEnergy said Tuesday that its Rossukon-2 exploration well in the Gulf of Thailand discovered an oil and gas pay zone.
The well, located in license G6/48, was drilled to a total depth of 5,460 feet in 210 feet of water.
Preliminary well logs indicate the well intersected about 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 at the well is expected to be completed by March 25.
Rossukon-2 will be plugged and abandoned after the logging program is complete and the Rossukon-2ST directional sidetrack well will commence drilling out 4,265 feet to the northwest.
The Rossukon oil accumulation was discovered in 2009.
License G6/48 covers 218 square miles over the Karawake Basin and lies to the north of the G10/48 licence where KrisEnergy is developing the Wassana oil field.
“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,” KrisEnergy’s director of exploration and production Chris Gibson-Robinson said.
KrisEnergy operates license G6/48 with a 30 percent working interest.
Thailand-based Northern Gulf Petroleum holds a 40 percent interest and Abu Dhabi-based Mubadala Petroleum holds a 30 percent interest.
