We present a fully 3D planar fracture model based on a finite element solution for fracture opening and a finite difference solution for slurry transport in the fracture. The new model can be used in cases with sufficient data gathered from logs, cores and micro-fracs. It can also be used in conjunction with fracture mapping to develop calibrated models that are based on the fundamental physics of fracturing.

Using novel numerical methods for the elasticity solution, we obtain an accurate description of the stress near the fracture tip. Combined with the physics of the cohesive zone model, this provides an appropriate description of fracture propagation. Benchmarking the model against laboratory tests shows a favorable comparison between modeling and observations.
