Case Study: BHP Petroleum achieves safer, more reliable multizone CT perforating with SLB ballistic delay fuse technology

BHP Billiton Uses Ballistic Delay Fuse to Streamline CT Perforating, Improving Safety and Reliability

SLB worked with BHP Billiton to improve the efficiency, safety, and reliability of multiple-zone coiled tubing perforating in the Eagleville field in South Texas. The challenge was to control which zone was perforated at different times in a single run without relying on extra gun spacers.

SLB used its ballistic delay fuse technology between guns, allowing separate-zone perforating in one CT run with a single firing head. The result was successful single-run perforating in eight wells, less rig-up and rig-down time, and reliable performance under 9,000 to 16,000 psi and temperatures up to 327 degF, with timing error kept within 6%.
