Introduction

The first true three-dimensional (3D) fracture model was developed by Clifton and Abou-Sayed [1,2]. The model is known as TerraFrac code. The code has been later expanded to include multiple fluids, proppant transport, thermal effect, and layered formation with different elastic moduli [3,4]. The TerraFrac code has often been used as a benchmark in verifying other fracture models by many authors. A 3D fracture model based on ...
