Study of Apparent Permeability in Shale Gas Reservoirs

Abstract

The permeability of reservoir plays an important role in modeling gas production form reservoir. The transport mechanism in shale gas reservoirs is significantly different from conventional reservoirs. As the gas is mostly stored in the organic matter, the transport mechanism of this gas mainly depends on the diffusivity and desorption of gas from the source. To have better understanding of the flow mechanism the concept of relative permeability is very important, which has more impact on the well performance in shale reservoirs. In this paper, we have explained about importance of relative permeability and the different techniques to determine the relative permeability.
