Embodiment Construction

In the following description, numerous details are set forth to provide an understanding of the present invention. However, it will be understood by those of ordinary skill in the art that the present invention may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.

The present invention generally relates to a technique for facilitating intervention operations with respect to subsea wells. The technique involves the use of a compliant guide deployed between a surface vessel and a subsea installation. The tool is coupled to a lower end of the compliant guide to enable selective movement of the lower end to a plurality of positions. For example, the tool can be used to move the lower end between an engaged position with the subsea installation and a remote parked position relative to the subsea installation. When in the engaged position, access is provided to the subsea installation and a wellbore beneath the ...

Abstract

A technique enables subsea intervention operations in which a compliant guide is deployed for connection with a subsea installation. A tool is provided to engage a lower end of the compliant guide in a manner that enables selective movement of the lower end between desired positions. For example, the tool may comprise a displacement mechanism that can be actuated to move the lower end of the compliant guide between an engaged position with the subsea installation and a remote parked position relative to the subsea installation.

Description

BACKGROUNDThe retrieval of desired fluids, such as hydrocarbon based fluids, is pursued in subsea environments. Production and transfer of fluids from subsea wells relies on subsea installations, subsea flow lines and other equipment. Additionally, preparation and servicing of the subsea well relies on the ability to conduct subsea intervention work.Subsea intervention work involves numerous challenges not normally faced when working on land wells or offshore platforms. In many cases, intervention in subsea wells is performed from a floating platform or ship by extending the borehole to a surface location by a tensioned riser. Also, compliant guides can be connected between the ship and a subsea installation so that various intervention tools can be moved through the compliant guide to the subsea installation and into a wellbore.Although many types of tools can be moved through the compliant guide, certain types of tools or tool strings are more easily deployed to the subsea facilit...
