Rossukon-3 is the third exploration well to be drilled in the G6/48 contract area in 2015 following the evaluation of Rossukon-2 and Rossukon-2ST, which were drilled in March.
Rossukon-2ST was drilled to a total depth of 2216m at a deviation of 57 degrees and Rossukon-2, located at a water depth of 210ft was drilled to a total depth of 5460ft.
Rossukon-3 lies 1.9km west of the Rossukon-2 surface location and 1.8km northwest of the original Rossukon-1 discovery well, drilled in 2009.
The well is planned to reach total depth at 2276m depth and will test Early Miocene fluvial sandstones on a broad structural high. Water depth at the Rossukon-3 well location is 208ft.
G6/48 covers 566sq km over the Karawake basin and lies to the north of the G10/48 licence, where KrisEnergy is developing the Wassana oil field.
KrisEnergy Ltd., 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, with 40% and Mubadala Petroleum with 30%.
KrisEnergy is using the Key Gibraltar jackup in a six-month contract 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.
In March, the joint venture made and oil and gas discovery at its first exploration well, the Rossukon-2, where preliminary logs indicated that the well intersected approximately 69ft true vertical depth (TVD) of net oil bearing sandstones and 37ft TVD of net gas-bearing sandstones, over five reservoir intervals. The well was drilled to a total depth of 5460ft. The Thai drilling campaign began only one week before the Rossukon-2 discovery.
