A common misconception is that conventional evaluation in thin beds usually under-estimates the petrophysical properties and that are generally true especially for porosity...

... petrophysical properties that can result from a combination of factors. Abstract The Granite Wash formation is made up of arkosic detrital material and is deposited as a series of overlapping submarine fans. These tight gas sands have very low porosity (<8%) and permeability (<.001 md). The Granite...

WAG injection reduces the effective fluid mobility not only in the layers with high permeability, but also in the adjacent layers with lower permeability. Consequently, the higher permeability layers receive a larger fraction of gas, which leads to reduction...
