GOHFER 9.4 planar 3-D geometry fracture simulator
GOHFER, which stands for Grid Oriented Hydraulic Fracture Extension Replicator, is a planar 3-D geometry fracture simulator with a fully coupled fluid/solid transport simulator. GOHFER was developed by Dr. Bob Barree of Barree & Associates in association with Stim-Lab, a division of Core Laboratories. GOHFER has been continually refined using established formulations that have been verified in Stim-Lab’s laboratory and in the field.

A regular grid structure is used to describe the entire reservoir, similar to a reservoir simulator. The grid structure allows for vertical and lateral variations, multiple perforated intervals as well as single and bi-wing asymmetric fractures to model the most complex reservoirs. GOHFER allows modeling of multiple fracture initiation sites simultaneously and shows diversion between perforations. The grid is used for both elastic rock displacement calculations as well as a planar finite difference grid for the fluid flow solutions. Fluid composition, proppant concentration, shear, leakoff, width, pressure, viscosity and other state variables are defined at each grid block.

The in-situ stress is internally calculated from pore pressure, poroelasticity, elastic moduli and geologically consistent boundary conditions. The width solution is fully 3-D allowing shear decoupling and local displacements that are controlled by local pressures and rock properties. Screenouts consider localized leakoff and proppant holdup and are not assumed to be caused by pad depletion or insufficient width. Fracture extension is based on a smoothly closing tip model and eliminates the fictitious singularity at the tip as well as the stress intensity factor.
