3. DESCRIPTION OF PROGRAM OR FUNCTION

HYFRACP3D is a finite element program for simulation of pseudo 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 three-layered system of rocks with variable rock mechanics properties.

4. METHOD OF SOLUTION

The program uses the finite element of solution. The model employs a numerical approach to solve the coupled non-linear partial differential equations for the fracture fluid pressure and induced fracture dimensions. The fracture is discretized into a number of vertical sections. Fracture width and pressure evaluations are conducted by applying to each vertical crack,the two-dimensional flow in the vertical direction with leak-off.

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. For PC use, the input is either typed onto the screen in program format if output is sent to  a file, or output is printed to screen if input is read from a file.

6. TYPICAL RUNNING TIME:  Approximate execution time is 5 CPU minutes.
ESTS0406/01
In the tests performed at the NEA/DB, only a few seconds are required to execute the sample problem on a PC DELL Pentium processor of 99 MHz.

7. UNUSUAL FEATURES OF THE PROGRAM

The program simulates the propagation of a three-dimensional hydraulic fracture due to constant injection rates. The program is capable of simulating the influences of variations in three rock layers, in situ stresses, mechanical properties and thicknesses.
