Karoon Energy Ltd. has begun the first of its planned four-well intervention campaign in Bauna oil field in the southern Santos basin offshore Brazil.
The Maersk Developer semi-submersible began operations at PRA-2 the weekend of May 7.
The intervention campaign aims to add 5,000-10,000 b/d of oil to Bauna production. It will comprise the installation of new electric submersible pumps in the Pr-2 and SPS-92 wells along with installation of gas-lift equipment in SPS-56 and reopening the lower zone of the BAN-1 well.
Karoon said the campaign is expected to take 4-5 months to complete.
Following that the rig will drill two new development wells on the nearby Patola field and, dependent on the required regulatory licenses, it will move to drill 1-2 control wells on the Neon oil discovery.
Neon light oil (39 degrees API) discovery was drilled by the Echidna-1 wildcat in licence BM-S-1037 in May 2015 when a production test flowed 4,650 b/d with the flow constrained by testing equipment. The discovery was then renamed Neon.
Karoon has 100% interest in the projects.
