The course is directed at engineering and geosciences professionals involved in hydraulic fracture stimulation of oil and gas wells. The primary focus is stimulation design for tight gas and unconventional reservoirs, but the topics covered apply generally to stimulation of all reservoirs including moderate to high permeability systems, and soft-rock applications.
The course covers the following topics:
Selection of stimulation methods
Damage remediation versus stimulation
Goals of stimulation for various reservoir types
Benchmarking well performance
Predicting Fracture Geometry
Design models and their assumptions
Effects of elastic coupling and induced shear on fracture geometry
Tip-process zone mechanisms and resistance to fracture extension
Complex fracturing and shear-dilation stimulation
Input Data for Fracture Design Models
Definition of rock elastic properties
Determining rock mechanics properties from core tests
Processing full-wave sonic logs for elastic properties
Deriving synthetic sonic logs and rock properties from conventional logs
Effect of pore pressure on fracture pressure and geometry
Model calibration and prediction of in-situ stress states
Height containment mechanisms other than stress contrast
Designing and Using Pre-Frac Injection Tests
Pre-frac step-rate injection tests
Holistic pressure falloff analysis
Effects of natural fractures
After-closure analysis and reservoir characterization
Perforating for Stimulation
Selecting optimum hole and charge size
Limited entry designs
Horizontal Well Stimulation
Transverse and longitudinal fracture design and performance
Selective frac initiation and diversion
Understanding and Predicting Fluid Leakoff
Influence of fluid properties on leakoff
Effects of natural fractures
