KrisEnergy Ltd, an independent upstream oil and gas company, has announced that the Key Gibraltar jack-up rig has commenced drilling of the Rossukon-3ST sidetrack exploration well in G6/48 in the Gulf of Thailand.
Fourth well in the Gulf of Thailand
Rossukon-3ST is the fourth well to be drilled in the G6/48 contract area in 2015 following successful results for the Rossukon-2, Rossukon-2STand Rossukon- 3 wells in March and early April. Rossukon-3ST will be drilled from the Rossukon-3 surface location and is planned to reach a total depth at 6689 ft (2039 m) measured depth (-4,500 ft true vertical depth subsea) with a maximum deviation of 74°. Water depth at the Rossukon-3 well location is 208 ft.
Chris Gibson-Robinson, Director Exploration & Production, commented: “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 km2 over the Karawake Basin and lies to the north of the G10/48 licence, where KrisEnergy is developing the Wassana oilfield. KrisEnergy took over operatorship of G6/48 in May 2014. 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%.
The Key Gibraltar jack-up rig is owned by Shelf Drilling (Southeast Asia) Limited. KrisEnergy contracted the rig for a firm 6 months for its Thai drilling program, which includes the latest Rossukon series of wells in G6/48 and 15 development wells in the Wassana oilfield.
