Well completion 1. Provide a means of casing suspension 2. Provides a means of tubing suspension. Provides a means of pressure sealing and isolation between casing at surface when many casing strings are used. 3. Provides pressure monitoring and pumping access to annuli between the different casing/tubing strings. 4. Provides a means of attaching a blowout preventer during drilling. 5. Provides a means of attaching a Christmas tree for production operations. 6. Provides a reliable means of well access. 7. Provides a means of attaching a well pump
4. A liner hanger is a device used in oil fields to hang liners within an oil well. So that oil can be pumped out of the well, a liner is used to create a vacuum. Liners can be installed mechanically or hydraulically, depending on the well. Setting a hanger is a crucial part of the process of "completion" which is the preparation of an oil well for drilling. à 5. The Y-tool is a solution to enable intervention or logging with wireline or coiled tubing below an ESP. it is installed on a production tubing and provides two separate conduits. One is concentric with a production tubing and enables access to the reservoir below the ESP. second is offset and used to support ESP system. 6. The packer isolates the annulus between the tubing and the inner casing and the foot of the well. This is to stop reservoir fluids from flowing up the full length of the casing and damaging it. It is generally placed close to the foot of the tubing, shortly above the production zone.

8. Side pocket mandrel- This is a welded/machined product which contains a "side pocket" alongside the main tubular conduit. The side pocket, typically 1" or 1½" diameter is designed to contain gas
Wireline entry guide. - This component is often installed at the end of the tubing, or "the shoe". It is intended to make pulling out wireline tools easier by offering a guiding surface for the toolstring to re-enter the tubing without getting caught on the side of the shoe Date: 2015-01-29; view: 7992
