Oilfield
inflow performance relationship
Oil & gas; Oilfield
A mathematical tool used in production engineering to assess well performance by plotting the well production rate against the flowing bottomhole pressure (BHP). The data required to create the IPR ...
pressure transient test
Oil & gas; Oilfield
A means of assessing reservoir performance by measuring flow rates and pressures under a range of flowing conditions and applying the data to a mathematical model. Fundamental data relating to the ...
tubing performance curve (TPC)
Oil & gas; Oilfield
A mathematical tool used in production engineering to assess the performance of the completion string by plotting the surface production rate against the flowing bottomhole pressure. The fluid ...
superposition in time
Oil & gas; Oilfield
A mathematical computation that accounts for the flow-rate history in analytical models generated to match with pressure-transient test data. The pressure-derivative response can be distorted in ...
tensor methods
Oil & gas; Oilfield
A mathematical entity with components that change in a particular way in a transformation from one coordinate system to another. Tensor methods are used in "upscaling" reservoir parameters for use in ...
productivity index (PI)
Oil & gas; Oilfield
A mathematical means of expressing the ability of a reservoir to deliver fluids to the wellbore. The PI is usually stated as the volume delivered per psi of drawdown at the sandface (bbl/d/psi).
