Mar 01, Colombo: Cairn Lanka, a wholly-owned subsidiary of Cairn India Ltd., exploring Sri Lanka's Mannar basin off northwest coast for oil has not found any gas or oil in the fourth well it drilled last month.
Following the successful completion of the first phase of oil exploration in Sri Lanka's Mannar basin, Cairn Lanka, has commenced second phase of operations last month.
The company in a press release said Thursday that it acquired 600 sq km of 3D seismic in Block SL 2007-01-001 in early 2012 and spud its fourth exploration well in the block on February 02.
Cairn said the well encountered multiple thick high quality reservoir sands, which were not hydrocarbon bearing.
The well has been plugged and abandoned while the rig is being demobilized. The Petroleum Resource Development Secretariat (PRDS) of Sri Lanka is being notified, Cairn said in the release.
The data from this well along with the results of the prior two discoveries are being integrated to fully understand the future block potential, the company further said.
The company brought forward their offshore exploration drilling from June to February due to early rig availability and excellent logistical preparations.
