Abstract
A technique for subsea intervention operations incorporates use of a compliant guide that extends between a surface location and a subsea installation. The technique facilitates deployment of tool strings into a subsea well. For example, a portion of the compliant guide can be used as a subsea lubricator during pressure deployment of tool strings. In some applications, a tool entry guide can be connected into the subsea installation to facilitate deployment of tool strings into the subsea well.
Claims24
A system for use with a subsea well, comprising:
- a guide disposed between a surface location and a subsea installation, wherein at least a lower portion of the guide serves as a subsea lubricator.
A method of intervening in a subsea well, comprising:
- coupling a guide between a surface location and a subsea installation;
- and
- utilizing at least a lower portion of the guide as a subsea lubricator during pressure deployment of a tool string.
A method of intervening in a subsea well, comprising:
- coupling a guide between a surface location and a subsea installation;
- and
- connecting a tool entry guide to the subsea installation such that an inlet of the tool entry guide is positioned externally of the guide.
A system for use with a subsea well, comprising:
- a subsea installation;
- a spoolable compliant guide coupled to the subsea installation;
- and
- a tool entry guide coupled to the subsea installation, the tool entry guide having a tool string inlet positioned externally of the spoolable compliant guide.
