MShale

MShale is a Discrete Fracture Network (DFN) simulator for predicting fracture propagation and extent in fractured and naturally fractured reservoirs. The 3D numerical simulator is designed to model multiple, cluster/complex/swarm, and discrete fractures in shale and coal bed methane (CBM) formations.

The multi-dimensional DFN solution is based on a network grid system and has options for Continuum Theory and Discontinuous (Grid). The program offers User Specified DFN characteristics where the fracture network spacing, aperture, and aspect ratios are input, and Deterministic DFN characteristics where the stress differences (i.e., σ2−σ3 and σ1−σ3) and network properties are specified. The fracture characteristics, apertures, and propagation in the x, y, and z directions (i.e., the x-z, y-z, and x-y planes) are then numerically calculated.

Fracture interaction can be User Specified or calculated Empirically based on the created network fractures and spacing. Proppant transport is also unique in that the proppant distribution can be Uniform, all in the Dominant fracture, or calculated according to a User Specified minimum allocation in the dominant x-z fracture plane.

MShale can also be used as a diagnostic tool to compare Discrete Fracture Network (DFN) numerical results with microseismic data. Download our MShale flyer or our DFN Model Presentation for more information.
