KrisEnergy (SGX:SK3) is to drill a sidetrack to its third well in the Gulf of Thailand, Rossukon-3, after it hit 124 feet of net pay.
The exploration well on block G6/48 in the Gulf of Thailand followed a successful evaluation of the Rossukon-2 and sidetrack wells in March.
Rossukon-3 was drilled to a total depth of 7,497 feet (2,285 metres) measured depth, or 6,235 feet true vertical depth subsea.
KrisEnergy said the well logs showed 75 feet true vertical depth of net oil-bearing sandstones and 49 feet of net gas-bearing sandstones over several reservoir intervals.
The well was 1.9 km west of the Rossukon-2 surface location and 1.8 km northwest of the original Rossukon-1 discovery well, drilled in 2009.
The sidetrack, Rossukon-3ST, is planned to down to a total depth of 6,689 feet (2,039m).
Chris Gibson-Robinson, director Exploration & Production, said: “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.”
G6/48 covers 566 sq. km over the Karawake Basin and lies to the north of the G10/48 licence, where KrisEnergy is developing the Wassana oil field.
KrisEnergy took over operatorship of G6/48 in May last year and holds a 30% working interest alongside Northern Gulf Petroleum with 40% and Mubadala Petroleum with 30%.
