A wireline-retrievable wellhead plug system for use with horizontal trees
One of the recent enhancements to offshore completion technology has been the development of a new horizontal tree design in which a wireline retrievable wellhead plug that serves as a primary barrier and permits vertical access to the well is used. The basic features of this removable plug system and what advantages it offers the operator will be presented in this paper. Also discussed will be the installation and retrieval techniques that are required to ensure system integrity. This wireline-retrievable wellhead plug system can be used with any horizontal tree for vertical access to the well and is particularly applicable to subsea completions in which wireline is the method of choice for installation and retrieval. The paper will focus on: Economic advantages of a wireline-retrievable wellhead plug system over methods that employ rod or diver manipulation.
