PART 3 Flashcards
An instrument that measures the specific gravity of a mixture of gas, liquid and solids
densimeter / densitometer
The difference between two pressure measurements
differential pressure
The portion of movement of a downhole pump at which the rods are going down and the downhole pump is being filled with fluid
down stroke
Mechanical or electronic devices for measuring various properties in the well such as pressure, fluid flow rate from each branch of a multilateral well, temperature, vibration, composition, fluid flow regime, and fluid holdup
downhole sensors
The difference between the average reservoir pressure and the flowing bottomhole pressure
draw down
The water and heavy hydrocarbons that condense from the gas stream and accumulate in the lower points of the flowlines
drip
The level to which the static fluid level drops in the tubing or casing when the well produced under pumping conditions
dynamic fluid level
An instrument used in sucker-rod pumping to record the variation between the polished rod load and the polished rod displacement
dynamometer
The record made by the dynamometer
dynamometer card
A type of gas-lift valve that allows a gas-lift port size to be adjusted remotely from surface to positions from fully open to closed
electric gas lift valves
Deployed offshore in locations that have limited access to pipelines to carry natural gas to the mainland
FLNG / floating liquefied natural gas vessel
A type of deliverability test conducted in gas wells to generate a stabilized gas deliverability curve (IPR), flowing the well under a constant rate until it reaches stabilized conditions (pseudosteady state)
flow after flow
A surface pipeline carrying oil, gas or water that connects the wellhead to a manifold or to production facilities, such as heater-treaters and separators
flow line
An instrument that measures the flow rate of fluids through a pipeline
flow meter
The flow of oil, gas or water through a pipe
flow stream
