A tubing hanger is a component used in the completion of oil and gas production wells. It is set in the tree or the wellhead and suspends the production tubing and/or casing. Sometimes it provides porting to allow the communication of hydraulic, electric and other downhole functions, as well as chemical injection. It also serves to seal-in the ...
Provides a means of tubing suspension (Tubing is removable pipe installed in the well through which well fluids pass). Provides a means of pressure sealing and isolation between casing at surface when many casing strings are used. Provides pressure monitoring and pumping access to annuli between the different casing/tubing strings.
THF – tubing hanger flange; THF – tetrahydrofuran (organic solvent) THP – tubing hanger pressure (pressure in the production tubing as measured at the tubing hanger [citation needed]) THRT – tubing hanger running tool; THS – tubing head spool; TIE – tie-in log; TIH – trip into hole; TIS – tie-in spool; TIT – tubing integrity test
The valve at the top is called the swab valve and lies in the path used for well interventions like wireline and coiled tubing. For such operations, a lubricator is rigged up onto the top of the tree and the wire or coil is lowered through the lubricator, past the swab valve and into the well. This valve is typically manually operated.
Casing hangers must be designed to take the full weight of the casing, and provide a seal between the casing hanger and the spool. Casing Hangers may also be suspended within the wellhead by means of radial distortion of the wellhead bore e.g. the "Pos-Grip" method. This is installed to support the individual casing strings in the well.
A pipe support or pipe hanger is a designed element that transfer the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation. The four main functions of a pipe support are to anchor, guide ...
