Cairn Lanka Ltd., a wholly owned subsidiary of Cairn India Ltd., has made a gas discovery in the CLPL-Dorado-91H/1z, an exploratory well drilled in 1,354 meters of water in block SL 2007-01-001, offshore Sri Lanka.

The well, drilled in the Mannar Basin, encountered a 25-meter gross hydrocarbon column in a sandstone reservoir between the depths of 3,041.8 and 3,068.7 meters measured depth. Measurement while drilling data indicate the zone is predominately gas bearing and also carries some liquid hydrocarbon potential. Cairn Lanka is the operator and holds 100% of the participating interest in the block. Further drilling is needed to establish commercial potential.

The company notes that the CLPL-Dorado-91H/1z is the first well to be drilled in Sri Lanka in 30 years and the first to discover hydrocarbons in the country.
