Geomechanical Template for Distributed Acoustic Sensing Strain Patterns during Hydraulic Fracturing

Yunhui Tan et al.

Summary: This study utilizes a fracture simulator combined with a finite element solver to analyze the strain field caused by hydraulic fracturing in shale. Various scenarios including single planar fractures, discrete fracture networks, and multiple fractures in both vertical and horizontal directions were studied. The results provide insights into the strain patterns and can guide engineers in optimizing well spacing and fracturing design for improved efficiency.
