.... These challenges included wellhead interfaces capable of handling the stack-up tolerances of casing hangers, and a need to orient the tubing hanger relative to a flowline connection system. The solution utilized by most conventional systems was the incorporation of a tubing head spool or some other elaborate means...

.... In this case it was decided to install the tubing hangers using simplified landing string technology, while a riser based light intervention system was selected to provide flexible options for VXT installation, well clean-up/ flow back and life of field well intervention.

The scope of this development included materials testing and qualification, elastomeric seals, metallic seals, gaskets, bolted flanges, a new family of gate valves and actuators, tubing hanger, tree components, and a series...

... Abstract The HPHT Metal-to-Metal Annulus Seal Assembly provides an all metal gas tight seal for the annulus between the 18 3/4″ wellhead housing and in-wellhead casing hangers. The seal is weight set with running string weight to achieve a low-pressure seal, then energized and locked using...

... Abstract Liner hangers are expected to maintain anchor capability and pressure integrity throughout the life of the well. For deepwater applications where hang weights, temperature requirements, and operational expenses can be considerably higher, liner-hanger performance is even more important...

... casing hanger/seal lockdown performance. This paper proposes what the authors believe should be considered the standard industry requirements for validating subsea seals/casing hangers, for casing hangers held in place by mechanical means, within the next generation of wellhead systems. The proposed...

... Abstract Spacing out production tubing and landing the tubing hanger in subsea completions is particularly challenging in wells with extreme well depths or in highly deviated well bores, as rig heave can significantly challenge space-out operations. Another problem also can occur when...
