Abandonment tool cuts time

June 26, 2012

Proserv unveiled a next-generation subsea cutting tool said to provide complete well severance and significantly reduce in-well operational time. The enhanced Multi-String Cutting (MSC) tool is a customisable internal multi-string conductor cutter that provides complete well severance from tool deployment to cutting operation and tool recovery within 12 hours, said Proserv.

First developed over two years ago in response to client demand for a specialist subsea cutting solution that severs fully grouted or nongrouted casing strings, the tool has undergone significant enhancements including an innovative new design of cutting head. It also now includes high-reliability wireless data transmission technology, removing the need for data cables while improving control.

When used in conjunction with Proserv’s water abrasive cutting technology, the 3m long and 200mm diameter tool is said to offer a superior cutting solution for the most challenging decommissioning and abandonment requirements. To date, it has severed 42 wells and the company expects its next-generation tool to surpass this in 2012.
