KrisEnergy's Rossukon-3 well hits oil, gas offshore Thailand
SINGAPORE -- KrisEnergy has announced that the Rossukon-3 exploration well in G6/48 in the Gulf of Thailand has encountered oil and gas bearing sandstones.
Rossukon-3, which was drilled by the Key Gibraltar jackup rig, was drilled to a total depth of 7,497 ft measured depth, or -6,235 ft true vertical depth subsea (TVDSS).
KrisEnergy’s preliminary interpretation of well logs indicates that the well intersected approximately 75 ft true vertical depth (TVD) of net oil-bearing sandstones and 49 ft TVD of net gas-bearing sandstones, over several reservoir intervals. Water depth at the Rossukon-3 location is 208 ft.
The well lies 1.9 km west of the Rossukon-2 surface location and 1.8 km northwest of the original Rossukon-1 discovery well, which was drilled in 2009.
Rossukon-3 will be plugged back and the G6/48 partners have agreed to immediately begin drilling the Rossukon-3ST sidetrack exploration well. Rossukon-3ST is planned to drill to a total depth of 6,689 ft measured depth at a maximum deviation of 74°.
“The three wells drilled so far in this campaign are promising and will increase the contingent resources in G6/48. Once Rossukon-3ST is completed, we will undertake a thorough technical review incorporating data from all the Rossukon wells, and the existing seismic data, to more fully assess the potential for commercial development in the future,” said Chris Gibson-Robinson, director E&P.
G6/48 covers 566 km2 over the Karawake basin and lies to the north of the G10/48 license, where KrisEnergy is developing Wassana oil field. KrisEnergy took over operatorship of G6/48 in May 2014.
KrisEnergy holds a 30% working interest in the concession and is partnered by Northern Gulf Petroleum with 40% and Mubadala Petroleum with 30%.
