KrisEnergy Ltd has reported that the Key Gibraltar jack-up rig has commenced drilling of the Rayrai-1 exploration well in block G10/48 in the Gulf of Thailand, where the company is currently developing the Wassana oilfield.
Rayrai-1 exploration well
Rayrai-1 is located in water depths of 170 ft (52 m) and lies 2.25 km north of the Niramai oil discovery drilled in 2009. The well is planned to reach total depth at 6382 ft (1945 m) measured depth (-5334 ft true vertical depth subsea) and will test Early Miocene stacked fluvial sandstones on a north-south trending faulted basement high.
Three oil discoveries in the licence
G10/48 covers 4696 km2 over the southern section of the Pattani Basin. The licence contains three oil discoveries – Wassana, Niramai and Mayura. KrisEnergy is developing the Wassana oilfield via a mobile offshore production unit producing to a floating storage offshore loading vessel. The Key Gibraltar jack-up rig will begin drilling up to 15 Wassana development wells once it has completed the Rayrai-1 exploration well. Production at Wassana is expected to commence in the second half of 2015 and plateau at 10 000 bpd of oil.
