The operation was carried out for CNR International (Cote d'Ivoire) S.A.R.L., a subsidiary of Canadian Natural Resources. Although BJ has used the RIS on numerous occasions around the world, this particular operation is special because it is the first time that the company has pre-installed conductors with the RIS in Cote d'Ivoire.
The million dollar-plus contract called for BJ to pre-install 12 conductors and supply cold cutting services on CNR's Project West Espoir Well Head Tower, located offshore Abidjan, Cote d'Ivoire. Using the RIS, directional drive shoes and the hydraulic S90 Hydrohammer, BJís hammer services specialists commenced operations in early December 2005. Working in depths of more than 400 feet (440 feet mudline penetration), BJ completed the entire operation by December 29--10 days ahead of schedule.
"To put it in perspective, the rigless operation will accelerate CNRís oil production by approximately 20 days because BJ carried out the work off the critical path for the rig," said Kenny Watt, division manager of BJ Tubular Services. "By the time the rig arrives, the conductors will already be driven, saving 20 days rig time. By completing this operation with the RIS, instead of a costly rig, CNR realized an incredibly impressive cost-savings."
BJ carried out the operation with a team of 13 dedicated personnel and state-of-the-art equipment. Hammer conductor-driving equipment was supplied by the company's base in Great Yarmouth, UK and the RIS was mobilized from its facility in Lafayette, Louisiana.
