... The high-porosity concept is an extended form of the partial monolayer of proppant, and the advantages of such a propped system have been discussed ( Darin and Huitt 1960 ; Fast and Flickinger 1963 ). By removing a portion of the proppant particles from the monolayer of proppant, the porosity...

... data come in. Abstract Our method to characterize a stimulated reservoir is a two-step process. In the first step, we match a microseismic (MS) pattern using a geomechanics model, which gives injection permeability and porosity. In the second step we match gas rate versus time using Production...
