PART 8 Flashcards
A measuring device for determining the gas-flow rate
Pitot tube
A type of gas-lift method that uses a plunger that goes up and down inside the tubing
plunger lift
A rod shorter than usual, usually placed below the polished rod and used to make a rod string of a desired length
pony rod
Volume of fluid injected in a well during hydraulic pumping
power fluid injection rate
In hydraulic pumping, the crude oil that is pressurized at surface to energize the bottom pump
power oil
The maximum pressure an electrical submersible pump can withstand
pressure capability
Also known as primary recovery, the first stage of hydrocarbon production, in which natural reservoir energy, such as gasdrive, waterdrive or gravity drainage, displaces hydrocarbons from the reservoir, into the wellbore and up to surface. Initially, the reservoir pressure is considerably higher than the bottomhole pressure inside the wellbore
primary production
The first stage of hydrocarbon production, in which natural reservoir energy, such as gasdrive, waterdrive or gravity drainage, displaces hydrocarbons from the reservoir, into the wellbore and up to surface
primary recovery
A procedure that involves sampling gas and liquid at different points across the diameter of pipe to evaluate the degree of stratification at a specific location
profile testing
type of a sucker rod-pumping unit that uses a rotor and a stator
progressive cavity pumping system
The cylinder of the downhole pump
pump barrel
A phenomenon produced when pump submergence into the fluid column is low
pump off
The difference in hydrostatic head between the pump depth and the dynamic fluid level above the pump
pump submergence
The relationship between actual pump displacement and the pump displacement under ideal conditions
pump volumetric efficiency / volumetric efficiency
A component of a production-logging tool that carries a radioactive solution (often carnotite) that can be selectively released into a flow stream
radioactive tracer
