The field is earmarked for development as feedstock gas to backfill the Darwin LNG plant. The US operator began a one well-plus-one option well programme last month using the semi-submersible Atwood Osprey at a dayrate of $185,000.

The drilling contractor Atwood Oceanics said in its latest quarterly report that it expected both wells to be drilled “based on discussions” with ConocoPhillips.
