PART 5 Flashcards
Water injected into the reservoir to pressurize and displace hydrocarbons to producing wells
injection water
A procedure conducted to establish the rate and pressure at which fluids can be pumped into the treatment target without fracturing the formation
injectivity test
A device made of rubber or polyurethane that has electronic devices
instrumented pig
A mathematical tool used in production engineering to assess well performance by plotting the well production rate against the flowing bottomhole pressure (BHP)
IPR / inflow performance relationship
A type of deliverability test conducted in gas wells used to generate a stabilized gas deliverability curve (IPR) without actually flowing the well for the time required to achieve stabilized conditions (pseudosteady state)
isochronal test
Liquid condensed by a scrubber following a compression and cooling process
knock out
A test to detect hydrogen sulfide in a fluid by discoloration of a paper moistened with the lead acetate solution
lead acetate test
The determination of the location of a leak in a pipeline
leak detection
Natural gas that contains a few or no liquefiable liquid hydrocarbons / Residual gas, mainly methane and ethane, that remains after the heavier hydrocarbons have been condensed in the wellhead
lean gas / dry gas
A gas condensate with low condensate formation in the reservoir (when the bottomhole pressure is reduced below the dewpoint pressure)
lean gas condensate
Liquid hydrocarbon utilized to remove heavier components from the gas stream in a gas processing plant
lean oil
Crude oil that has a high API gravity, usually more than 40o
light crude oil
Hydrocarbons with low molecular weight such as methane, ethane, propane and butane
light hydrocarbons
Natural gas, mainly methane and ethane, which has been liquefied at cryogenic temperatures
LNG / liquefied natural gas
Gas mainly composed of propane and butane, which has been liquefied at low temperatures and moderate pressures
LPG / liquefied petroleum gas
