Fundamentals of Heavy Oil Recovery and Production
Published in Cesar Ovalles, Subsurface Upgrading of Heavy Crude Oils and Bitumen, 2019
Many crude oil wells require artificial lift to produce oil to the surface. Sucker rod pumping (SRP), electrical submersible pumping (ESP), jet hydraulic pumps, and gas-lift are the various modes of artificial lift currently used. However, when heavy oils and bitumens are encountered, these methods of artificial lift fail to provide the necessary pressure for the crude to reach the surface [Awarval et al. 2015]. In some fields, electrical submersible (or submergible) pumps or ESPs are favored because of the significant drawdown they can produce. ESPs comprise a series of rotating turbine type blades that have the drawback of being very sensitive to even small amounts of sand production. Pump failures can form the primary component of operating expenditures in such fields [Smalley 2000].

Artificial lift refers to the use of external means to help lift the well fluids from the bottom of the well to the surface. Essentially, artificial lifting enables well production at lower bottom-hole pressures. It may be applied on a flowing well to increase its production in order either to meet market demands or to make the project economics more attractive. Artificial lifting is mostly applied, however, to wells which otherwise would not produce at all or would produce below the economic limit of operation.

In later life, with almost no gas, require artificial lift in order to raise fluids to the surface and obtain maximum oil recovery which may now possibly comprise less than 20% oil and 80% water. Artificial lift systems include rod pumping using a pumping jack (nodding donkey) as a prime mover, gas lifting (gas injection), hydraulic pumping (water injection), and centrifugal pumping. A combination of gas and/or water injection and pumps might be required to bring the fluids to the surface.

In order to boost the flow of liquids from a production well, such as water or crude oil, the term "artificial lift" is used. In most cases, this is accomplished by inserting a mechanical device within the well or by introducing gas into the liquid farther down the well to lighten the hydrostatic column (Schlumberger 2017). Although it is frequently utilized in naturally flowing wells to increase flow rate, artificial lift is required in the well when there is not enough pressure in the reservoir to elevate the generated fluid to the surface. The following list of artificial lift equipment types is provided: Gas LiftESPPCPRod Pump
Optimization of production and lift-gas allocation to producing wells by a new developed GLPC correlation and a simple optimization method

With population growth and economic development, the demand for energy will increase. Oil and gas support the largest portion of energy in the world. However, the production is decreasing in most of the petroleum reservoirs around the world. Thus, there is a high effort to manage and optimize the oil and gas production. When the pressure of the reservoir is less than the pressure to produce or the favorable production rate is higher than the rate that the reservoir can create in the natural blow out situation, it is necessary to utilize one of the artificial lift methods. The purpose of artificial lift is to create a lower bottom-hole pressure that the formation can make a higher flow to the bore hole (Schlumberger Well Completions and Productivity, 1999).
