... Abstract In order to better understand reservoir behavior, reservoir engineers make sure that the model fits the data appropriately. The question of how well a model fits the data is described by a match quality function carrying assumptions about data. From a statistical perspective, improper...

Results from the sensitivity analysis show that the error on surface area calculation ranges from 1% – 323% due to the constant permeability assumption...

Traditionally the approach was: For single-phase liquid flow (oil or water): variation of liquid and rock properties with pressure is assumed to be negligible. Under this assumption the diffusivity equation has constant coefficients and can be solved analytically...
