  2. Gas lift - Wikipedia

    en.wikipedia.org/wiki/Gas_lift

    The gas-lift mandrel is a device installed in the tubing string of a gas-lift well onto which or into which a gas-lift valve is fitted. There are two common types of mandrels. In a conventional gas-lift mandrel, a gas-lift valve is installed as the tubing is placed in the well. Thus, to replace or repair the valve, the tubing string must be pulled.

  3. Dry gas seal - Wikipedia

    en.wikipedia.org/wiki/Dry_gas_seal

    The original patent was for Kaydon's "Tapered Ramp" lift geometry, a constant diameter / variable depth dynamic lift design. From that first dry gas seal ever manufactured for a centrifugal compressor in 1951, Kaydon Ring & Seal has been instrumental in developing the dry gas seal into one of the most reliable and maintenance free sealing ...

  4. Petroleum production engineering - Wikipedia

    en.wikipedia.org/wiki/Petroleum_production...

    Petroleum production engineers design and select subsurface equipment to produce oil and gas well fluids. [1] They often are degreed as petroleum engineers, although they may come from other technical disciplines (e.g., mechanical engineering, chemical engineering, physicist) and subsequently be trained by an oil and gas company.

  5. Annulus (well) - Wikipedia

    en.wikipedia.org/wiki/Annulus_(well)

    The 'A' annulus can serve a number of crucial tasks, including gas lift and well kills. A normal well will also have a 'B' and frequently a 'C' annulus, between the different casing strings. A normal well will also have a 'B' and frequently a 'C' annulus, between the different casing strings.

  6. Production packer - Wikipedia

    en.wikipedia.org/wiki/Production_packer

    A production packer [1] is a standard component of the completion hardware of oil or gas wells used to provide a seal between the outside of the production tubing and the inside of the casing, liner, or wellbore wall. Based on their primary use, packers can be divided into two main categories: production packers and service packers.

  8. Drill stem test - Wikipedia

    en.wikipedia.org/wiki/Drill_stem_test

    A drill stem test (DST) is a procedure for isolating and testing the pressure, permeability and productive capacity of a geological formation during the drilling of a well. The test is an important measurement of pressure behaviour at the drill stem and is a valuable way of obtaining information on the formation fluid and establishing whether a ...

  9. Slickline - Wikipedia

    en.wikipedia.org/wiki/Slickline

    Slickline is more commonly used in production tubing. The wireline operator monitors at surface the slickline tension via a weight indicator gauge and the depth via a depth counter 'zeroed' from surface, lowers the downhole tool to the proper depth, completes the job by manipulating the downhole tool mechanically, checks to make sure it worked if possible, and pulls the tool back out by ...
