Lightweight elevators designed for running and retrieving the sucker-rod string in wells equipped with a rod pump. Rod elevators can be used on a workover rig or a rod unit specifically designed for ...

liquid hydrocarbons

Oil & gas; Oilfield

Liquid compounds such as propanes, butanes, pentanes and heavier products extracted from the gas flowstream.

recoverable gas lift gas

Oil & gas; Oilfield

Injection gas that has returned to surface and it is not reinjected into the gas-lift system. Instead, it is transferred to a pipeline. This gas is sometimes called spent gas-lift gas.

core testing

Oil & gas; Oilfield

Laboratory analyses performed on formation core samples as part of a stimulation-treatment design process. Tests such as the formation flow potential, fracture orientation and fluid compatibility ...

core analysis

Oil & gas; Oilfield

Laboratory study of a sample of a geologic formation, usually reservoir rock, taken during or after drilling a well. Economic and efficient oil and gas production is highly dependent on understanding ...

in situ

Oil & gas; Oilfield

In the original location or position, such as a large outcrop that has not been disturbed by faults or landslides. Tests can be performed in situ in a reservoir to determine its pressure and ...

effective velocity

Oil & gas; Oilfield

In the context of spinner flowmeters, the apparent fluid speed measured by the spinner as the tool is moved up and down the well. The effective velocity is the algebraic sum of the actual fluid ...
