Multiple simplistic simulation models were history matched to existing production wells. Wide uncertainty exists in many key...

... by gas production. This permeability reduction is more pronounced in tight sand reservoirs due to shear dilation of micro-fractures. In order to model stress dependent permeability, a fully coupled finite element geomechanical reservoir simulations is needed. However, since a large number of data...

... with conventional methods in offset wells. The study includes the use of advanced modeling software, coupled with microseismic evaluation and comparison of conventional job designs with the channel-fracturing approach, to evaluate the impact on fracture geometry. The results of the study indicate that the channel...

... Abstract Microseismic measurements provide qualitative information about where a fracture stimulation goes. However, there is also quantitative information, which has largely been neglected. We have developed a geomechanical model to predict the extent of shear failure during fracture...

.... A petrophysically rigorous fundamental model of TGSS that accounts for microporosity would make the evaluation, development and stimulation of tight gas sandstone development more robust. The reduced connectivity of matrix pores has a profound effect on transport properties such as absolute and relative...

... Abstract We combine a new pore-scale model with a reservoir simulation algorithm to predict gas production in gas-bearing shales. It includes an iterative verification method of surface mass balance to ensure real-time desorption-adsorption equilibrium with gas production. The pore-scale model...
