A jet pump is one of artificial lift methods, and it can be applied when depth and deviation of producing wells increase and reservoir pressure depleted (Figure 14). A jet pump is used in thermal production as it’s not directly affected by the high temperature of the fluids.
What is used to artificially lift a well production?
The major forms of artificial lift are: Sucker-rod (beam) pumping. Electrical submersible pumping (ESP) Gas lift and intermittent gas lift. Reciprocating and jet hydraulic pumping systems.
How is a pump able to lift water from a well?
Water is pumped from a well by creating a partial vacuum above the water by the pump. The amount of vacuum, in inches of mercury, is equal to the weight of the column of water from the water table to the surface. Atmospheric pressure at sea level is 29.92 inches (approx. 76 cm) of mercury.
What are the types of pumps?
There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
Various positive-displacement pumps
- Rotary lobe pump.
- Progressive cavity pump.
- Rotary gear pump.
- Piston pump.
- Diaphragm pump.
- Screw pump.
- Gear pump.
- Hydraulic pump.
Can a water pump pump oil?
Pump has two seals, both sealing suction pressure. Usually higher flow rate applications than end suction pumps. Water and relatively thin liquids (won’t pump thicker oils). …
Why do most hydraulic lifts use oil instead of gas?
A gas is not used in hydraulic machines as the fluid because gas is easily compressible and so if a gas is used, the energy would mostly go into compressing a gas. Therefore a liquid is used in hydraulic machines as the fluid.
How much does a hydraulic lift Cost?
Hydraulic elevators: Hydraulic elevators cost around $30,000 to $40,000. Pneumatic elevators: Pneumatic elevators are easier to install which keeps installation costs down.
Which liquid is used in hydraulic lift?
Most industrial hydraulic lift systems will use an oil as their incompressible fluid.
How deep can a pump lift water?
The atmospheric pressure would be capable of sustaining a column of water 33.9 feet in height. If a pump could produce a perfect vacuum, the maximum height to which it could lift water at sea level would be 33.9 feet, as shown in Example 1.
What are the 4 types of wells?
Types of Wells
- Drilled wells. Drilled wells are constructed by either cable tool (percussion) or rotary-drilling machines. …
- Driven wells. Driven wells are constructed by driving a small-diameter pipe into shallow water-bearing sand or gravel. …
- Dug wells.
