Meeting the deepwater challenge

摘要

The AX-S subsea well intervention system is one of the most significant and innovative pieces of technology the subsea industry has seen and is specifically designed to directly address some of the unique operation demands of the deepwater subsea environment. IT IS WIDELY recognised that while subsea well intervention is necessary, traditional methods can make it a time consuming and very costly activity, with drilling and semi submersible rig costs running at up to US$lmn to $1.4mn a day spread rate. There are more than 4,000 oil and gas producing subsea wells worldwide and this number is increasing at a rate of approximately 500 a year. With many such wells over a decade old, intervention is crucial to allow for maximum oil and gas extraction.
