ABU DHABI, UAEMubadala Energy has made a potentially large gas discovery with its first deepwater well, Layaran-1 in the Andaman Sea, 100 km offshore North Sumatra, Indonesia.

Initial results suggest potential for more than 6 Tcf in place.

The well was drilled in the South Andaman Gross Split PSC in 1,207 m of water and to a depth of 4,208 m. It encountered an extensive gas column more than 230 m thick in an Oligocene sandstone reservoir.

Data acquisition included wireline, coring, sampling and a DST, during which the well flowed more than 30 MMcf/d of good-quality gas.

This was Mubadala’s second Oligocene gas find in the Andaman area following last year’s Timpan-1. Harbour Energy subsidiary Premier Oil South Andaman is the other partner in the production sharing contract.

Next, the rig will drill the Harbour-operated Halwa and Gayo wells on Andaman II.
