Exploration

Cairn Lanka (Private) Limited, a wholly owned subsidiary of Cairn India Limited, has successfully completed the first phase of the exploration campaign in Sri Lanka Block SL-2007-01-001. The exploration programme involved the acquisition, processing and interpretation of 1,753 sq km of 3D seismic data and a three well deep water drilling programme. This programme resulted in two successive gas and condensate discoveries: the CLPL Dorado- 91H/1z well and, the CLPLBarracuda-1G/1 well. The third well, CLPL-Dorado North 1- 82K/1 was plugged and abandoned as a dry hole on 14 December, 2011.

The operations were conducted safely, in accordance with the highest global standards, within schedule, budget and in compliance with Sri Lankan regulations. Cairn Lanka’s successful drilling programme – the first in Sri Lanka in 30 years – has established a working petroleum system in the frontier Mannar Basin.

Following this success, Cairn Lanka has entered the second phase of exploration with the approval of the Government of Sri Lanka. Additional 600 km2 3D seismic data has been being acquired which will firm up several promising leads and prepare the Operator for further exploration drilling in mid CY 2013.
