Ductile fracture modeling : theory, experimental investigation and numerical verification
The fracture initiation in ductile materials is governed by the damaging process along the plastic loading path. A new damage plasticity model for ductile fracture is proposed. Experimental results show that fracture initiation in uncracked ductile solids is sensitive to the hydrostatic pressure …

Fracture Modeling and Flow Behavior in Shale Gas Reservoirs Using Discrete Fracture Networks
Fluid flow process in fractured reservoirs is controlled primarily by the connectivity of fractures. The presence of fractures in these reservoirs significantly affects the mechanism of fluid flow. They have led to problems in the reservoir which results in early water breakthroughs, reduced …

Post-treatment horizontal hydraulic fracture modeling with integrated chemical tracer analysis, a case study
… from the chemical tracer study, hydraulic fractures were calibrated to match the fractional production from each interval. The fracture model provides insight into what the hydraulic fractures look like, potential communication avenues for the chemical tracers, and production efficiency.

A novel diagnostic fracture injection test workflow considering natural fractures
Applications of diagnostic fracture injection test (DFIT) are used in unconventional reservoirs to determine reservoir characteristics for future fracture design and production. DFIT consists of creating a minifrac by pumping small amounts of water and monitoring the pressure response. The presence …

Production performance evaluation of energized fracturing fluids in unconventional formations
… can vary significantly perhaps because of better fracture containment and lower rock water sensitivity in some fields. Across all the areas studied, foam completions on average were found to have 5-20% lower costs and lower water and proppant requirements by 72-87% and 7-38%, respectively. …
