Abstract

The invention relates to a tree plug for a tree of the type used in the oil and gas exploration and production industry. The invention also relates to a plug and to a lock adapted to be located in various types of downhole tubing, and to a method of plugging a tree bore. In one embodiment, a tree plug (16,17) for a tree (10) having a main tree bore (14) is disclosed, the tree plug having a plug body (22) , a number of locking members (24) mounted for radial movement relative to the plug body between retracted and extended positions, a radially expandable seal element (26) , and a mandrel (28). The mandrel is translated relative to the plug body to urge the locking-members to the extended position, and to exert an axial force on the seal element to radially expand the seal element, to thereby lock and seal the plug within the tree bore.
