ProCISE Casing Cutting and Recovery System | Schlumberger


Casing cutting and recovery system

Sever, engage, and remove casing in a single trip

The ProCISE casing cutting and recovery system severs a single string of casing and engages it for removal—all in one operation. In contrast to conventional methods, in which one cut and recovery can take up to three consecutive trips, the ProCISE system is capable of performing one or multiple cuts and latching onto the casing for recovery, in a single trip.

Effective casing engagement and cutting ‭‬‬‬‬‬

The ProCISE casing cutting and recovery system’s inline casing spear engages the casing and applies overpull to hold the casing in tension while cutting. To minimize rig time and cost, the ProCISE system has a multicycle pipe cutter, which enables performing multiple casing cuts during a single run.

Reliable casing recovery ‭‬‬‬‬‬

When the ProCISE system completes a cut, the ‭system hydraulic packoff is placed at the top of the cut ‭casing string, and the inline casing spear is reengaged at the ‭top of the casing segment in need of recovery. The inline casing spear can be engaged and released multiple times. This makes it possible to optimize spear placement at the top of the casing segment, which enables hanging the recovered casing in the rotary table while the spear is released and workstring is racked out of the way. By using the ProCISE system, the crew can handle the casing with greater efficiency and safety as it is removed from the wellbore. ‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬ When circulation is reestablished, the inline casing spear enables returns flow to the outside of the casing string, facilitating efficient ‭circulation of any cement solids or gas that might be trapped ‭in the annulus. ‭‬‬‬‬‬‬‬‬‬‬‬‬‬‬‬
