Cairn Spies Oil Offshore Greenland
The following operational update concerns Cairn's exploration drilling campaign offshore Greenland.
The multiple-objective Alpha-1S1 well has reached an intermediate depth of 4,358 meters (m) in volcanic sections. Following the conducting of extensive logging operations the well is now being deepened. The well has encountered gas shows in silty and volcanic sections over several hundreds of meters. Oil has also been observed intermittently over a 400m section in the volcanic and volcano-clastic intervals of the well which requires further evaluation.
Initial geochemical analysis of various hydrocarbon samples recovered from the well, undertaken by independent UK laboratories, confirms the presence of two oil types which have different origins and levels of maturity and are the first oils encountered in the current exploration campaign. Further geochemical analysis are ongoing on a number of oil samples.
The T8-1 well, which, as announced on August 24, 2010, encountered gas in thin sands, reached a TD of 3,250m. The well has been plugged and abandoned. The T8-1 well did not result in a commercial discovery, consequently the well costs of US $84.2 million excluding demobilization costs, the majority of which were incurred after June 30, 2010, have been written off in accordance with Cairn's accounting policies.
The T4-1 exploration well is located more than 100km north of Alpha and T8 and the well is currently drilling ahead at 1,900m.
Sir Bill Gammell, Chief Executive said, "The T8, Alpha and T4 wells are the first wells in Cairn's exploration program in Greenland and are also the first wells ever drilled in the Baffin Bay Basin which is similar in size to the North Sea.
The presence of both oil and gas confirms an active, working petroleum system in the basin and is extremely encouraging at this very early stage of our exploration campaign for the Sigguk block and the entire area."
