Abstract:
A reservoir simulator system models the effect of proppant damage on reservoir production through calculation of a fracture closure stress versus fracture permeability relationship, which is mathematically transformed into a pore pressure versus fracture permeability relationship. Based upon the pore pressure relationship, the system models reservoir production while taking into account the permeability reduction in the fractures brought about due to proppant damage.
