The line of sucker rods is represented in this diagram by the solid black line in the center of the well. A sucker rod is a steel rod, typically between 7 and 9 metres (25 and 30 ft) in length, and threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well.
A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor) to the vertical reciprocating motion necessary to drive the polished-rod and accompanying sucker rod and column (fluid) load. The engineering term for this type of mechanism is a walking beam.
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.
Petroleum production engineers' responsibilities include: Evaluating inflow and outflow performance between the reservoir and the wellbore.; Designing completion systems, including tubing selection, perforating, sand control, matrix stimulation, and hydraulic fracturing.
A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial vacuum. [ 1 ] Suction cups occur in nature on the bodies of some animals such as octopuses and squid , and have been reproduced artificially for numerous purposes.
Modern sucker gigging uses specially constructed jon boats that have a set of lights mounted on the bow of the boat and a railing around the bow that allows the "gigger" to stand up and peer out in front of the boat in an attempt to locate and gig fish. [3] The lighting system is often powered by gas, a generator, or a battery. A fish gig

Derrickhands are more experienced workers who assemble the pump truck, monitor circulations and handle pipe and rods on the elevated tubing board. [7] The most experienced member of a service rig crew is the driller, who runs the control panel next to the rig floor, controls the height of the derrick, monitors the roughnecks and derrickhands ...
