Schlumberger shows new coiled tubing selective perforating system

Offshore staff

HOUSTON – Schlumberger has followed up its introduction at the ICoTA annual meeting and exhibition of ACTive Straddle with the introduction of its ACTive OptiFIRE coiled tubing selective perforating system.

OptiFIRE permits real-time selective perforating and activation using fiber-optic telemetry. Schlumberger has said the selective perforation process is repeatable at different precise depths with positive indication of each firing and hydrostatic pressure control in a single run.

The ACTive OptiFIRE system can arm the perforating guns on demand, and fire each gun individually from the bottom up and is repeatable up to 10 times. It does not require a ball drop, pressure pulse system, or fluids to detonate.

“Operators currently have no method for perforating multiple non-contiguous zones when deploying guns on coiled tubing without requiring multiple runs or using a CT logging reel,” said Sameh Hanna, president, Well Intervention, Schlumberger. “The ACTive OptiFIRE system facilitates efficient operations with fiber-optic real-time telemetry for depth correlation and selective activation and confirmation. Eliminating the need to pump fluid to detonate reduces the overall perforating costs and improves hydrocarbon-to-market time for our customers.”
