WebAbstract. This paper presents the results of laboratory measurements of relativepermeabilities to oil and gas on small core samples of reservoir rock by fivemethods, and describes the influences of such factors as boundary effect, hysteresis, and rate upon these measurements.

Membrane permeability is also a key determinant for drug absorption, distribution, and elimination. Diffusion, that is, the migration of matter down a concentration gradient, is a simple mechanism by which both endogenous and drug molecules can enter …
