SINGAPORE – KrisEnergy Ltd. has drilled the Rossukon-2ST side track exploration well in G6/48 in the Gulf of Thailand following the Rossukon-2 oil and gas discovery.
Rossukon-2ST was drilled to a TD of 7,270 ft (2,216 m) measured depth (5,263 ft TVD subsea) at a deviation of 57°. KrisEnergy said preliminary well logs indicates that the well intersected approximately 40 ft (12 m) TVD of net oil-bearing sandstones and 100 ft (30.5 m) TVD of net gas-bearing sandstones, over several intervals.
The Key Gibraltar jackup rig, which drilled the Rossukon-2ST well, is owned by Shelf Drilling (Southeast Asia) Ltd. KrisEnergy has contracted the rig for a firm six months for its Thai drilling program, which includes the Rossukon series of wells in G6/48 and 15 development wells in the Wassana oil field.
Chris Gibson-Robinson, director Exploration & Production, said: “The Rossukon-2ST exploration side track has encountered the highest net pay of the three discovery wells drilled so far within the Rossukon area and also extends the area over which hydrocarbon bearing reservoirs are present some 1.8 km (1.1 mi) northwest of the original 2009 Rossukon-1 discovery well. The results are encouraging and we are in discussion with our partners about the next steps to fully determine hydrocarbon volumes in the Rossukon area.”
G6/48 covers 566 sq km (219 sq mi) over the Karawake basin and lies to the north of the G10/48 license, where KrisEnergy is developing the Wassana oil field. The company holds a 30% working interest in the concession and is partnered by Northern Gulf Petroleum Pte Ltd. with 40% and Mubadala Petroleum with 30%.
