3. DESCRIPTION OF PROGRAM OR FUNCTION

HYFRAC3D is a finite element program for simulation of three-dimensional fracture geometries with a two-dimensional planar solution. The model predicts the height, width and winglength over time for a hydraulic fracture propagating in a multi-layered system of rock with variable fluid flow and rock mechanics properties.

4. METHOD OF SOLUTION

The program uses the finite element method of solution. A backward difference scheme is used by taking the weight functions on the time axis. This implicit time matching scheme requires iteration since the fracture configuration at time t+td is not known.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Graphics output is not available and program is limited to fracture propagation in a single plane without proppant transport.

[ top ]

6. TYPICAL RUNNING TIME: Approximate execution time is 15 CPU minutes.

[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

The program simulates the propagation of a three-dimensional hydraulic fracture due to variable injection rates. The program is capable of simulating the influences of variations in rock layer number, permeability, porosity, mechanical properties and thickness.
