The six year agreement (with option for two additional years) that begins in June 2010 is expected to result in approximately $800m in revenues over the life of the contract. This contract routinely serves six to ten drilling rigs offshore Cabinda, Angola in blocks 0 (shallow water) and block 14 (deepwater).

Chris Rivers, president and CEO of M-I Swaco, said: “The continuation of our relationship with Cabinda Gulf Oil company is truly valued. This award demonstrates our leadership in providing best-in-class solutions in the highly technical and challenging offshore market of Angola.”

Houston, Texas-based M-I Swaco is jointly owned 60% by Smith International and 40% by Schlumberger.
