... Abstract The diffusivity equation for naturally fractured reservoirs represented by dual-porosity systems has been solved as a function of dimensionless times (t 0 ) and dimensionless water influx (Q (t))for various ratios of aquifer to reservoir size. Results are presented in a similar...

... permeability, slip coefficient, inertial parameter and rock compressibility values have been considered. In addition, the predictions take into account changes in gas properties with pressure. Solutions for these two types of boundary conditions are shown at much larger values of the dimensionless time than...
