Key Features and Capabilities

Fracture Dynamics Modeling

GOHFER excels in simulating the intricate behaviors of hydraulic fractures within geological formations. The software can model the initiation and propagation of multiple fractures, accounting for complex geometries and the influence of natural fractures. It offers detailed analysis of fracture surface area, width, height, and length, providing engineers with a comprehensive understanding of fracture network development.

Fluid and Solid Interaction Analysis

A core capability of GOHFER is its advanced fluid-structure interaction analysis. This feature allows for the simultaneous simulation of fluid flow dynamics within the fractures and the mechanical response of the rock mass. By coupling these phenomena, the software provides a more realistic depiction of how fluid pressure affects fracture opening and propagation, and how the solid mechanics of the formation influence fluid flow, crucial for accurate modeling of fracturing events.

3D Stress Modeling

The software incorporates robust 3D stress modeling capabilities, representing the in-situ stress tensor in three dimensions. This detailed stress analysis is vital for understanding fracture containment, re-orientation, and the potential for creating complex fracture networks. By accurately modeling stress distributions and variations, GOHFER enables more precise predictions of fracture geometry and its impact on reservoir conductivity.
