An assembled length of sucker rods used to connect and power a rod pump with the reciprocating power source at surface.
Industry:Oil & gas
An assembly of components and controls necessary to provide a hydraulic power supply. In modern oilfield activities, many systems are hydraulically powered, including the majority of mobile systems such as slickline units, coiled tubing units and snubbing units. In most cases, a diesel engine is the prime mover, providing an independent power supply that is harnessed to the necessary hydraulic pump and control systems.
Industry:Oil & gas
An artificial-lift system that utilizes a downhole pumping system that is electrically driven. The pump typically comprises several staged centrifugal pump sections that can be specifically configured to suit the production and wellbore characteristics of a given application. Electrical submersible pump systems are a common artificial-lift method, providing flexibility over a range of sizes and output flow capacities.
Industry:Oil & gas
An artificial-lift system that operates using a downhole pump. A surface hydraulic pump pressurizes crude oil called power oil, which drives the bottom pump. When a single production string is used, the power oil is pumped down the tubing and a mixture of the formation crude oil and power oil are produced through the casing-tubing annulus. If two production strings are used, the power oil is pumped through one of the pipes, and the mixture of formation crude oil and power oil are produced in the other, parallel pipe.
Industry:Oil & gas
An artificial-lift method principally used in gas wells to unload relatively small volumes of liquid. An automated system mounted on the wellhead controls the well on an intermittent flow regime. When the well is shut-in, a plunger is dropped down the production string. When the control system opens the well for production, the plunger and a column of fluid are carried up the tubing string. The surface receiving mechanism detects the plunger when it arrives at surface and, through the control system, prepares for the next cycle.
Industry:Oil & gas
An artificial-lift method, used in relatively low-productivity wells, in which the gas-lift system is operated on an intermittent basis to enable the buildup of liquids in the wellbore.
Industry:Oil & gas
An artificial-lift pumping system using a surface power source to drive a downhole pump assembly. A beam and crank assembly creates reciprocating motion in a sucker-rod string that connects to the downhole pump assembly. The pump contains a plunger and valve assembly to convert the reciprocating motion to vertical fluid movement.
Industry:Oil & gas
An array induction whose transmitters and receivers are arranged to produce a null reading in free space, that is, which has the mutual signal balanced to zero.
Industry:Oil & gas
An artificial-lift method in which gas is injected into the production tubing to reduce the hydrostatic pressure of the fluid column. The resulting reduction in bottomhole pressure allows the reservoir liquids to enter the wellbore at a higher flow rate. The injection gas is typically conveyed down the tubing-casing annulus and enters the production train through a series of gas-lift valves. The gas-lift valve position, operating pressures and gas injection rate are determined by specific well conditions.
Industry:Oil & gas
An artificial-lift method in which the gas-lift system is operated on a continuous basis to sustain liquid production at an efficient rate.
