Greenland

HOUSTON, Sept. 21 – Cairn Energy PLC plans to plug the T8-1 well off western Greenland and write off $84.2 million of well costs excluding demobilization costs.

The well found gas in thin sands but did not result in a commercial discovery. TD is 3,250 m.

Cairn will deepen the multi-objective Alpha-1S1, which has reached 4,358 m in volcanic sections. Extensively logged, the well has encountered gas shows in silty and volcanic sections over several hundred meters, and oil has also been observed intermittently over a 400-m section in the volcanic and volcaniclastic intervals which require further evaluation.

Initial geochemical analysis of various hydrocarbon samples confirms the presence of two oil types of different origins and levels of maturity and are the first oils encountered in the current exploration campaign. Geochemical analyses continue.

The T4-1 exploratory well more than 100 km north of Alpha and T8 is drilling at 1,900 m.

The wells, on the Sigguk block, are the first in the Baffin Bay basin.
