Effect of lateral stress on rock fracture permeability

There are contradiction conclusions from different experimenter of the influence of lateral stress on rock fracture permeability.The reason for this is that the lateral stress has multi-aspect influences on a fracture.The lateral stress may cause crack opening increase,fracture wall attrition and filing compression.All of these have different influences on the fracture permeability.Expression of the influences of three-dimensional stress on the fracture permeability has been established accordin...
