Schlumberger has launched a new instrumented wireline intervention service, ReSOLVE, which delivers monitoring and control of wireline workover operations to reduce intervention costs, the oil and gas tech firm said on Tuesday.

ReSOLVE services provide real-time measurement and control in a small footprint. Their downhole intelligence allows for an unprecedented level of detail in intervention operations, said Schlumberger Wireline president Catherine MacGregor.

“With this unique technology, more complex operations can be performed, such as selective sleeve shifting or safety valve performance evaluation, with unprecedented success.”

The wireline system includes a high-force linear actuator which shifts downhole valves, pulls retrievable plugs, and can perform fishing operations as well as monitor force and displacement in real time; a universal shifting tool (UST) that can selectively shift devices below restrictions; a hydraulic setting tool which eliminates the need for explosives; and a milling tool which maximizes the rate of penetration and removes scale and other obstructions from wellbore tubulars.

In a North Sea well, ReSOLVE milling service removed scale at a rate of 57 feet per hour over thousands of feet of production tubing, eliminating the need for a full scale intervention. In the Middle East, the ReSOLVE UST was deployed to selectively shift 10 valves in a horizontal multizone completion. Real-time confirmation of shifting eliminated the need for production logging to verify the valves had shifted.
