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.
Key Features
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.
The width solution is fully 3-D allowing shear decoupling and local displacements are controlled by local pressures and rock properties.
Screen outs consider localized leak off and proppant holdup and are not assumed to be caused by pad depletion or insufficient width.
Most models assume linear-elastic deformation of a fully coupled rock mass.
In shales the assumption of shear is critical.
Along with this GOHFER accounts for pressure dependent leak off, transverse storage in horizontal and off-angle fracture components, and pressure dependent modulus of the bulk rock mass.
