2. Tubing hanger - Wikipedia

   en.wikipedia.org/wiki/Tubing_hanger

   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 ...

3. Completion (oil and gas wells) - Wikipedia

   en.wikipedia.org/wiki/Completion_(oil_and_gas_wells)

   The tubing hanger may be manufactured with rubber or polymer sealing rings to isolate the tubing from the annulus. The tubing hanger is secured within the tubing head flange with lag bolts. These lag bolts apply a downward pressure on the tubing hanger to compress the sealing gaskets and to prevent the tubing from being hydrostatically or ...

4. Production tubing - Wikipedia

   en.wikipedia.org/wiki/Production_tubing

   Tubing is a smaller diameter pipe that is run inside of the production casing. A packer is usually set at the lower end of the casing to prevent formation fluid from entering the annulus between the tubing and the casing. A packer is an elastomer cylinder that forms a pressure seal between the tubing and the casing.

   Drill pipe (#16) is a joint of hollow tubing used to connect the surface equipment to the bottom hole assembly (BHA) and acts as a conduit for the drilling fluid. In the diagram, these are stands of drill pipe which are 2 or 3 joints of drill pipe connected and stood in the derrick vertically, usually to save time while tripping pipe.

6. Wellhead - Wikipedia

   en.wikipedia.org/wiki/Wellhead

   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.

7. Casing (borehole) - Wikipedia

   Casing Diameters of a Borehole Casing Diagram premium gas tight connections on a casing string. Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream.

9. Casing hanger - Wikipedia

   en.wikipedia.org/wiki/Casing_hanger

   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.
