KrisEnergy encounters hydrocarbons at Rossukon-3 offshore Thailand

14th April 2015

KrisEnergy has announced that the Rossukon-3 exploration well in G6/48 in the Gulf of Thailand has encountered oil-and-gas-bearing sandstones over several reservoir intervals

KrisEnergy has announced that the Rossukon-3 exploration well in G6/48 in the Gulf of Thailand has encountered oil-and-gas-bearing sandstones over several reservoir intervals
G6/48 covers 566 square kilometres over the Karawake Basin and lies to the north of the G10/48 licence, where KrisEnergy is developing the Wassana oil field.

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 (TVDSS).

KrisEnergy’s preliminary interpretation of well logs indicates that the well intersected approximately 75 feet true vertical depth (TVD) of net oil-bearing sandstones and 49 feet TVD of net gas-bearing sandstones over several reservoir intervals. Water depth at the Rossukon-3 location is 208 feet.

The well lies 1.9 kilometres west of the Rossukon-2 surface location and 1.8 kilometres northwest of the original Rossukon-1 discovery well, drilled in 2009.

Rossukon-3 will be plugged back and the G6/48 partners have agreed to immediately begin drilling the Rossukon-3ST sidetrack exploration well.

Rossukon-3ST is planned to drill to a total depth of 6,689 feet (2,039 metres) measured depth (-4,500 feet TVDSS) at a maximum deviation of 74 degrees.

“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,” said Chris Gibson-Robinson, director Exploration & Production.

G6/48 covers 566 square kilometres 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. The company holds a 30 per cent working interest in the concession and is partnered by Northern Gulf Petroleum Pte Ltd with 40 per cent and Mubadala Petroleum with 30 per cent. The Key Gibraltar jack-up rig is owned by Shelf Drilling (Southeast Asia) Limited. KrisEnergy contracted the rig for a firm six months for its Thai drilling program, which includes the latest Rossukon series of wells in G6/48 and 15 development wells in the Wassana oil field.
