Web“Pseudo-steady-state” flow is defined as a flow regime where the pressure at any point in the reservoir declines at the same constant rate over time. This flow condition prevails after the pressure funnel shown in Fig. 3.1 has propagated to all no-flow boundaries.

In scientific literature, we know that the condition for incompressible flow is that the particular derivative of the fluid density ρ is zero: D ρ D t = 0. and for steady flows the condition is that the partial derivative with respect to time is zero ( ∂ ρ ∂ t = 0). However, the definition of the particular derivative is: the avett brothers - magpie and the dandelionWebTransient flow at constant rate from an infinite-acting reservoir in terms of pseudopressure ψ (pwf) is modeled by Eq. 5-39: A plot of Δ ψ [= ψ ( pi) − ψ ( pwf )] versus t on semilog coordinates should give a straight line of slope m, from which.
