KrisEnergy’s Rossukon-2ST sidetrack exploration well in G6/48 in the Gulf of Thailand has encountered 40 feet of net oil bearing sandstones and 100 feet of net gas-bearing sandstones, over several reservoir intervals.
The well was drilled after the announcement on March, 24, 2015 of the Rossukon-2 oil and gas discovery. Rossukon-2ST was drilled to a total depth of 7,270 feet (2,216 metres) measured depth (-5,263 feet true vertical depth subsea) at a deviation of 57 degrees.
Chris Gibson-Robinson, Director Exploration & Production, said: “The Rossukon-2ST exploration sidetrack 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 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 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 2014. It holds a 30% working interest in the concession and is partnered by Northern Gulf Petroleum Pte Ltd with 40% and Mubadala Petroleum with 30%. The Key Gibraltar jack-up rig, which drilled the Rossukon-2ST well, is owned by Shelf Drilling (Southeast Asia) Limited. 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.
