Abstract: The present invention relates to methods and apparatus for expanding tubulars in a wellbore. In one aspect of the invention, an expansion tool with hydraulically actuated, radially expandable members is disposed on a string of coil tubing. In another aspect of the invention the apparatus is utilized to expand a tubular lining a lateral wellbore into contact with a window of a larger tubular lining a central wellbore.

Abstract: The present invention provides methods and apparatus for cutting tubulars in a wellbore. In one aspect of the invention, a cutting tool having radially disposed rolling element cutters is provided for insertion into a wellbore to a predetermined depth where a tubular therearound will be cut into an upper and lower portion. The cutting tool is constructed and arranged to be rotated while the actuated cutters exert a force on the inside wall of the tubular, thereby severing the tubular therearound. In one aspect, the apparatus is run into the well on wireline which is capable of bearing the weight of the apparatus while supplying a source of electrical power to at least one downhole motor which operates at least one hydraulic pump. The hydraulic pump operates a slip assembly to fix the downhole apparatus within the wellbore prior to operation of the cutting tool. Thereafter, the pump operates a downhole motor to rotate the cutting tool while the cutters are actuated.

Abstract: A connector arrangement used for connecting a first tubular to a second tubular. The first tubular member has at least one circumferential ring profile, and the second tubular member has a corresponding number of matching circumferential ring profiles. When the ring profiles of the two tubulars are mated and interlocked, they form separate and independent fluid seals as well as a mechanical lock able to hold the tubulars together during future expansion of the entire tubular and joint. Further, selecting properties of the tubulars such as yield strength and modulus of elasticity or constraining a diameter of one of the tubulars during expansion or compression forms a tight connection due to elastic recovery of the tubulars.

Abstract: A lockout tool dimensioned to be received within a housing of a subsurface safety valve (SSV). The lockout tool generally comprises an elongated housing, and an expander mandrel slidably received within the housing. Together, the elongated housing and expander mandrel are run into the wellbore and landed into the housing of the SSV such that the end of the expander mandrel opens the flapper valve. A portion of the lookout tool housing shoulders against the flow tube in the SSV to drive the flow tube downward, thereby maintaining the flapper of the SSV in its open position. As the expander mandrel moves downward through the hard scat of the SSV, the mandrel engages the flow tube and expands it against the hard seat. In this manner, the flow tube is expanded into permanent, frictional engagement with the hard seat. This, in turn, looks the flapper member of the SSV in its open position.
