Modeling Hydraulic-Fracture Treatments in San Juan Basin Coals: Fully Functional 3D Fracture Model

摘要

The two main objectives for a hydraulic-fracture model in coals are optimization of job design and placement, and post-treatment diagnostics. Fully functional 3D models can be used to obtain good estimates of the fracture dimensions. A grid-oriented fully functional 3D fracture simulator with shear decoupling can be especially useful in coals for post-treatment diagnostics if sufficient input data can be fixed from logs and diagnostic fracture-injection tests (DFITs).
