Dr. Sarvaramini has recently developed a new paradigm (STimsIM software) for modelling of the HF with the ability of integration into the reservoir simulation programs. Dr. Sarvaramini initially started STimsIM development at the University of Waterloo with collaboration with Dr. Robert Gracie at Civil and Environmental Engineering Department and Dr. Maurice Dusseault at the Earth and Environmental Science Department. In this new paradigm, an equivalent poro-elasto-plasto continuum zone of enhanced permeability represents the Stimulated Reservoir Volume. The details of the complex fracturing, nucleation and micro-events of void coalescence in the discrete level are not explicitly modelled; instead, their aggregate effects are translated into continuum constitutive laws for permeability and plasticity degradation, and internal physical parameters representing natural fractures.
