KrisEnergy has commenced drilling of the Rossukon-2 exploration well using the Key Gibraltar jack-up rig in G6/48 in the Gulf of Thailand, where the Rossukon oil accumulation was discovered in 2009.

Rossukon-2 lies 1 kilometres northeast of the Rossukon-1 discovery well.

The well is planned to reach total depth at 1,665 metres measured depth and will test Early Miocene stacked fluvial sandstones on a broad structural high.

The well will also appraise the Rossukon-1 reservoir, which tested 850 b/d, and is designed to identify additional volumes of oil that could move the discovery closer to commercial development.

Water depth at the Rossukon-2 well location is 210 feet.

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. 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.
