Multiple cluster perforations are typically used for multi-stage hydraulic fracturing of horizontal wells with casing hole completion to create multiple fractures in any single stage. Due to the mechanical interaction of fractures, the local principal stresses field may alter, which affects the fracture complexity. To optimize the network fracturing design, 3D multiple fractures propagation, stress...
This paper presents an analysis of the environmental impacts during hydraulic fracturing process of shale gas in Tunisia. The different steps of hydraulic fracturing process of shale gas such as site preparation, exploration, development, production, distribution and closing wells are described to analyze operation of the process. A Life Cycle Assessment (LCA) approach was achieved out focusing on...
