Paper Number: SPE-199986-MS
... included petrophysical and geomechanical properties along with a 2D discrete natural-fracture network representing the distribution of natural fractures in the reservoir. Hydraulic fractures in parent wells were modeled using original stress settings from the 3D-MEM. Then, a dynamic model was constructed...

Paper Number: SPE-199997-MS
...-stimulated compared to historical average stimulation metrics, i.e. fewer stages/clusters and larger spacing, lower proppant loading, and less fluid volume pumped, were chosen as the final candidates for geomechanical modeling. Third, the wells were modeled with in-house advanced geomechanical fracture...
