Everything You Need to Know About Artificial lift Pump Systems

Using artificial ways to boost liquid flow, such as water or crude oil, from production is an artificial lift system. A mechanical component known as a pump or velocity string inside the well can be used in an artificial lift system. Introducing gas into the liquid down the well reduces the hydrostatic column weight.

Fremont, CA: The artificial lift system comprises pumping systems and gas lift, a technique applied to oil wells to raising reservoir pressure. This is done to induce oil to rise to the surface. If the reservoir's inherent drive energy is insufficient to force the oil to the surface, artificial lift is used to recover the maximum output. While some wells have sufficient pressure for oil to ascend to the surface naturally without stimulation, the majority don't, necessitating artificial lift.

Artificial lift pump systems

Using artificial ways to boost liquid flow, such as water or crude oil, from production is an artificial lift system. A mechanical component known as a pump or velocity string inside the well can be used in an artificial lift system. Introducing gas into the liquid down the well reduces the hydrostatic column weight.

It is employed in naturally flowing wells to enhance the flow rate over what would normally flow. However, it is required in wells when there is insufficient pressure to push the generated fluids to the surface. The generated fluid might be oil, water, or a combination of both. Usually, it is blended with a small amount of gas.

Methods of Artificial Lift:

Beam Pumping

Beam pumping uses equipment that operates above and below the surface to increase pressure but also pushes oil to the surface, is the most widely employed artificial lift pump system. Beam pumps are similar to jack pumps found in onshore oil wells. Hydraulic pumping equipment uses a downhole hydraulic pump rather than sucker rods to lift oil to the surface.

Rod Pumping

Rod Pumping system design is relatively straightforward, and the units may be quickly and cheaply switched to various wells. It is practical, straightforward, and easy to use. It can pump a well down to the lowest pressure (depth and rate dependent). The system is organically vented for gas separation & fluid level soundings. It is suited to thin holes and numerous completions.

Hydraulic piston pumps

From a depth of 18,000 feet (5486 m), hydraulic piston pumping can rise; from 15,000 feet, it can produce 500 B/D (79.49 m3/d) (4572 m); depending on the model of the pump being utilized, crooked holes provide little difficulty. Both the installation and the power source can be installed remotely.

In cities, hydraulic piston pumping is discreet, adaptable, and matches output to a healthy delivery. Diesel, natural gas, or electricity may be power sources. Power fluids can be used to install or retrieve downhole pumps. Power fluids can be combined with inhibitors to prevent corrosion, scale buildup, emulsions, etc.

Gas Lift

Large solids may be handled using a gas lift with minor issues. It can handle high-PI wells with continuous lift and volumes of up to 50,000 B/D (7949.37 m/d). It may change from constant to intermittent, elevate a chamber or plunger, and decelerate. It is discrete in metropolitan areas, and the power supply may be positioned remotely. It covers offshore. Obtaining downhole pressures and gradients is simple; with a wireline unit, it may be serviced. Straight holes don't pose an issue, and corrosion is typically better.

Hydraulic jet pump

A hydraulic jet pump can create 25,000 B/D (3975 m3/d) from 5,000 feet and lift objects up to 20,000 feet (5486 m) in the air (1520 m). In cities, it is undetectable. There are no issues with crooked holes. The installation may be evaluated, and the power source can be located remotely; the power fluid can be used to install or retrieve downhole pumps.

Flexible hydraulic jet pumps can effectively match production to delivery; their power source options are electricity, natural gas, or diesel. Any liquid may be used as a power fluid. Trained workers pump liquid generated from the well in cycles, whether water or oil. No evidence of clogging caused by sand production.

Hydraulic jets can be employed on offshore platforms. The resulting fluid's viscosity can be reduced by heating the power fluid and adding other liquids (like diesel) to it. There is no evidence that a jet pump has ever produced an emulsion. Inhibitors can be used with power fluid to reduce corrosion, scale, emulsions from reservoirs, etc.
