Cairn Energy closed its drilling programme for offshore Greenland coinciding with the end of the drilling season, as agreed by the Greenland Bureau of Minerals and Petroleum.

The firm suspended its Alpha-1S1 exploration well in the Sigguk block, which is located about 175km off the shore of Disko Island, west Greenland, to allow possible re-entry to sidetrack or deepen the well at a later date.

The Alpha-1S1 well encountered oil shows in the volcanic section, however, drilling was stopped with the well still in volcanics and the prognosed Mesozoic section not yet reached.

Cairn also plugged and abandoned the T8-1 and T4-1 exploration wells because neither well resulted in commercial discoveries.

The T4-1 well failed to encounter any significant hydrocarbons and found only thin reservoir sands.
