2. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.

3. Steam-assisted gravity drainage - Wikipedia

   en.wikipedia.org/wiki/Steam-assisted_gravity...

   High pressure steam is continuously injected into the upper wellbore to heat the oil and reduce its viscosity, causing the heated oil to drain into the lower wellbore, where it is pumped out. Dr. Roger Butler, engineer at Imperial Oil from 1955 to 1982, invented the steam assisted gravity drainage (SAGD) process in the 1970s. Butler "developed ...

   TFE – total fina elf (obsolete; Now Total S.A.) major French multinational oil company [30] TFL – through flow line; TFM – tubular feeding machine; TGB – temporary guide base; TGT / TG – tank gross test; TGOR – total gas oil ratio (GOR uncorrected for gas lift gas present in the production fluid [citation needed]) TH – tubing hanger

5. Completion (oil and gas wells) - Wikipedia

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

   On wells with gas lift capability, many operators consider it prudent to install a valve, which will isolate the A annulus for the same reasons a DHSV may be needed to isolate the production tubing in order to prevent the inventory of natural gas downhole from becoming a hazard as it became on Piper Alpha.

6. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main if the sewage is transported some significant distance. The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4]

7. Artificial lift - Wikipedia

   en.wikipedia.org/wiki/Artificial_lift

   Artificial lift is the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well (known as pump or velocity string) or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well.
