KrisEnergy announces discovery at Rossukon-3

KrisEnergy Ltd. (“KrisEnergy”), an independent upstream oil and gas company, provides an update on the Rossukon-3 exploration well in G6/48 in the Gulf of Thailand, which was drilled by the Key Gibraltar jack-up rig following the successful evaluation of the Rossukon-2 and sidetrack wells in March 2015. 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 km west of the Rossukon-2 surface location and 1.8 km 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. 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 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. 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 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.

KrisEnergy completes Rossukon-2 sidetrack well

KrisEnergy Ltd. (“KrisEnergy”), an independent upstream oil and gas company, provides an update on the drilling of the Rossukon-2ST sidetrack exploration well in G6/48 in the Gulf of Thailand, which was drilled following the announcement on 24th March 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. KrisEnergy’s interpretation of preliminary well logs indicates that the well intersected approximately 40 feet true vertical depth (“TVD”) of net oil-bearing sandstones and 100 feet TVD of net gas-bearing sandstones, over several reservoir intervals. Chris Gibson-Robinson, Director Exploration & Production, commented: “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. The Company took over operatorship of G6/48 in May 2014.
