MELBOURNE, Australia — Karoon Energy Ltd.'s contract with Maersk Drilling for the Baúna intervention campaign has started, following the receipt of all permits and regulatory approvals required for the Maersk Developer drilling rig to commence operations.

After loading supplies and equipment for the program, the rig departed Rio de Janeiro on May 8 and arrived at the PRA-2 well site in license BM-S-40 (Baúna), southern Santos Basin on May 11, according to a recent Karoon Energy news release. The rig moored, using pre-installed mooring buoys, and the first Baúna intervention in the four-well campaign began on May 15.

The intervention campaign, which is aiming to add 5,000 bbl/d to 10,000 bbl/d of oil to Baúna production, comprises the installation of new electric submersible pumps in the PRA-2 and SPS-92 wells, installation of gas-lift equipment in SPS-56 and reopening of the lower zone of the BAN-1 well.

The campaign is anticipated to take four to five months to complete. The Maersk Developer rig is then scheduled to drill two development wells on the Patola Field and, subject to the receipt of required regulatory licenses, one or potentially two control wells on the Neon oil discovery.

A week ago, Karoon Energy exercised options to increase the scope of the Maersk Developer semisubmersible rig offshore Brazil, with drilling of up to two wells at the Neon Field.
