KrisEnergy hits pay at Rossukon-2 well

  • Exploration & Production

KrisEnergy, an independent upstream oil and gas company, has encountered oil and gas at Rossukon-2 exploration well in G6/48 in the Gulf of Thailand, where the Rossukon oil accumulation was discovered in 2009.

KrisEnergy started drilling the Rossukon-2 well on March 17, 2015 with a Key Gibraltar jack-up rig.

Rossukon-2, which is located at a water depth of 210 feet, was drilled to a total depth of 5,460 feet (1,664 metres) measured depth (-4,924 feet true vertical depth subsea). According to KrisEnergy, preliminary well logs indicate that the well intersected approximately 69 feet true vertical depth (TVD) of net oilbearing sandstones and 37 feet TVD of net gas-bearing sandstones, over five reservoir intervals.

The logging program is expected to be completed by March 25, 2015 at which point Rossukon-2 will be plugged back and the Rossukon-2ST directional sidetrack well will start drilling out approximately 1.3 km to the northwest, KrisEnergy said in the statement.

Chris Gibson-Robinson, Director Exploration & Production, commented: “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. These wells, together with the original 2009 discovery well, will bring us a step closer to deciding commerciality of the accumulation and the potential development concept.”

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. The company 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 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 Rossukon-2 in G6/48 and 15 development wells in the Wassana oil field.
