Results from the rig-site analysis indicate elevated levels of carbon dioxide. bp will now begin laboratory analysis to further characterize the reservoir and fluids discovered, which will provide additional insight into the potential of the Bumerangue block. Further appraisal activities are planned to be undertaken, subject to regulatory approval.
“We are excited to announce this significant discovery at Bumerangue, bp’s largest in 25 years,” Gordon Birrell, EVP, production & operations said.
