What is artificial lift in the oilfield?

What is artificial lift in the oilfield?

Artificial lift is a method used to lower the producing bottomhole pressure (BHP) on the formation to obtain a higher production rate from the well. This can be done with a positive-displacement downhole pump, such as a beam pump or a progressive cavity pump (PCP), to lower the flowing pressure at the pump intake.

What is the most common form of artificial lift?

Rod Lift via Pump Jack The most common example and recognizable method of artificial lift is rod lift. Rod lift is done using a pump jack at the surface. A pump jack goes by many different terms, including sucker rod pump (SRP), horse head, dinosaur, and nodding donkey.

Which method of artificial lift is the most efficient?

Since the use of PCP pumps in oil wells requires relatively simple surface and downhole installations with low levels of energy losses in system components, PCP systems are the most efficient among the artificial lift methods.

What is artificial lift services?

Artificial lift is a process used on oil wells to increase pressure within the reservoir and encourage oil to the surface. When the natural drive energy of the reservoir is not strong enough to push the oil to the surface, artificial lift is employed to recover more production.

Why is artificial lift required?

Artificial lift is needed in wells when there is insufficient pressure in the reservoir to lift the produced fluids to the surface, but often used in naturally flowing wells (which do not technically need it) to increase the flow rate above what would flow naturally.

Is artificial lift secondary recovery?

Production using artificial lift is considered primary recovery. The primary recovery stage reaches its limit either when the reservoir pressure is so low that the production rates are not economical, or when the proportions of gas or water in the production stream are too high.

What are the different types of artificial lift?

Artificial lift systems fall into two basic types: pumping and gas lift. Pumping systems include electric submersible pumps, beam pumps, progressing cavity pumps, plunger lifts and hydraulic pumps.

What criteria are considered when selecting an artificial lift method?

The geographical and environmental circumstances as the dominant factors for Artificial Lift selection and also some other subordinate factors such as: reservoir pressure, productivity index, reservoir fluid properties and inflow performance relationship were considered by him (Neely et al., 1981).

How many types of artificial lifts are there?

What is an artificial lift engineer?

Field Engineer, Artificial Lift Provide testing, repairs, and routine servicing on equipment in the shop and the field. In addition, help generate business to increase revenues through sales of Weatherford products and services.

What is the difference between IOR and EOR?

The main difference between IOR and EOR is that EOR approach is used to recover mostly immobile oil that remains in the reservoir after application of primary and secondary methods while IOR strategies are used to recover mobile oil. But sometimes, IOR is used to recover a immobile oil as well.
