Numerical and Experimental Investigations of the Interactions between Hydraulic and Natural Fractures in Shale Formations

Energies, 2018
Natural fractures (NFs) have been recognized as the dominant factors that increase hydraulic fracture complexity and reservoir productivity. However, the interactions between hydraulic and natural fractures are far from being fully understood.

UNDERSTANDING NATURALLY FRACTURED RESERVOIRS

Scientific Contributions Oil and Gas, 2022
Naturally fractured reservoir differs from clastic reservoirs in the sense that the concepts of porous media which were usually applied for clastic reservoir analysis must be modified. This means that handling naturally fractured reservoir is also different compared to handling clastic reservoir.
