Abstract:

Recent advances in fracture-diagnostic tools and fracture-propagation models make it necessary to efficiently and accurately model fractures with complex geometries in reservoir-simulation studies. In this talk, we will present an innovative method to model fractures with complex geometries with any third-party reservoir simulators in a non-intrusive manner. Through nonneighboring connections (NNCs), an embedded discrete fracture model (EDFM) preprocessor is developed and applied to any commercial reservoir simulators to properly model fractures with complex geometries such as irregular fracture networks, nonplanar hydraulic fractures and natural fractures. We demonstrate the accuracy and efficiency of the approach by comparing the results with local-grid-refinement (LGR) models and its filed applications. The nonintrusive application of the EDFM allows insertion of the discrete fractures into the computational domain and the use of original functionalities of the simulators without having access to the source code of the simulators. It may be easily integrated into existing frameworks for unconventional reservoirs to handle gas Huff-n-Puff simulation, well interference due to complex fracture hits, automatic history matching, and well spacing optimization.
