Paper presented at the SPE Low Perm Symposium, May 5–6, 2016
Paper Number: SPE-180230-MS
.... The method combines three important reservoir engineering concepts for linear flow analysis: dynamic drainage area (DDA), material balance, and decoupling of saturation and pressure (which is analogous to the decoupling of geomechanics and fluid flow). The DDA concept, which uses a time-dependent well...

...Abstract Abstract In tight gas sandstone the productivity of a well is sometimes quite different from that of a nearby well. Several mechanisms for this observation have been advanced. Of interest in this paper is the possibility that a small change in water saturation can change the gas phase...
