Fracture Formation & Development
Key to developing unconventional shale reservoirs is an understanding of how hydraulic fractures develop and their impact on fluid flow
Hydraulic fracture formation and development will vary in different shales due to distinct compositions, textures and stress regimes. These may control hydraulic fracture initiation plus their geometry and extent, but further research is required to delineate how these controls can be predicted.
The length of time hydraulic fractures stay open for at formation pressures and temperatures is also presently poorly understood.
