pseudopressure plot

1. n. [Well Testing]
A plot of real gas pseudopressure (pseudopotential) m(p) versus time function used to analyze gas-well drawdown and buildup tests. The use of the real gas pseudopressure linearizes the diffusion equation for gas flow. This form enables rigorous analysis over all pressure ranges. The pressure-squared plot can be used for low pressure (p < ~2000 psi), and pressure can be used to analyze gas-well tests at high pressure (p > ~3000 psi).
