- Description
- This work presents theory for modeling of fracture propagation within reservoir simulator,
history matching of field injection pressure using uncoupled and fully coupled geomechanical injection models, and sensitivity study of various parameters such as permeability enhancement/reduction functions, limiting length of fracture propagation, stress factor, and Biot’s
constant. Two wells completed in tight gas sands in Western Canadian sedimentary basin were
studied. The wells were fractured with different techniques (i.e., X-link gelled water fracs (Well
A) and un-gelled slick water fracs (Well B)) and were both successfully matched with coupled
geomechanical model.
