It is rather easy to measure the length and diam-eter of a pipe and compute its flow capacity as a function ofpressure; however, in porous media flow is different in thatthere are no clear-cut flow paths which lend themselves Analysis of fluid flow in porous media has evolvedthroughout the years along two fronts: the experimental andthe analytical. Physicists, engineers, hydrologists, and thelike have examined experimentally the behavior of variousfluids as they flow through porous media ranging from sandpacks to fused Pyrex glass.
1.1.3 Reservoir geometry The shape of a reservoir has a significant effect on its flow behavior. Most reservoirs have irregular boundaries and a rigorous mathematical description of their geometry is often possible only with the use of numerical simulators. However, for many engineering purposes, the actual flow
