Paper Number: SPE-12585-PA
Published: 01 December 1985
... where the rock properties first change may be approximately determined. The effect of heterogeneities on the pressure-drop profile is demonstrated with analytical solutions and laboratory experiments. I is a number that depends only on the relative permeabilities, viscosity ratio, and critical...

...J. G. J. Ypma A two-dimensional (2D) analytical model is presented for gas/oil gravity drainage in a homogeneous, dipping reservoir. The sensitivity of gas/oil gravity drainage to key variables such as injection rate, oil relative permeability, and permeability anisotropy can be determined quickly...

... the identifiability of the parameters. The identifiability of porosity and absolute and relative permeabilities on the basis of flow and pressure data in a two-phase (oil/water) reservoir is considered. The question posed is: How accurately can one expect to estimate spatially variable porosity and absolute...
