Marathon Oil Corporation announced on 14 July that it has achieved first gas production through its new Alba B3 offshore compression platform. Production from the B3 platform allows Marathon to convert some 130m boe of proved undeveloped reserves, more than doubling the company’s remaining reserve base in Equatorial Guinea. “The Alba B3 compression project will allow us to maintain plateau production for the next two years, mitigating base decline, while extending the Alba field’s life by up to eight years,” said Marathon vice-president, conventional, Mitch Little.
