ABSTRACT:
A technique for subsea intervention operations enables pressure control to be accomplished at the surface while borehole fluid control is exercised at the seabed. A compliant guide extends between a subsea well installation and a surface location, such as a surface intervention vessel. A buffer fluid is deployed within the compliant guide to maintain the borehole fluids proximate the seabed. The buffer fluid also enables pressure control over the buffer fluid and the borehole fluid to be performed from the surface. Additionally, a flexible conveyance can be used to move intervention tools through the compliant guide.
