Results are presented for three‐dimensional planar fracture propagation in the presence of variations in confining stress, reservoir properties and frac‐fluid viscosity when the well‐bore pressure is constant throughout the frac‐job. Solid rock deformation during the frac‐job is described by the dislocation method with singular integral equations, and the fluid flow in the fracture is represented by the finite element method. A convergence study is undertaken on the three‐dimensional numerical model, and good agreement is obtained with results from laboratory tests and from the simpler circular model.
