Fracture Stability

Logview and stereonet outputs

Fracture stability provides a logview and stereonet plot output.In the logview the input data (log and fracture orientations) are displayed. The output of the algorithm us the evaluation of the Mohr-Coulomb failure criterion fore each fracture orientation. Green values display stable and red values display unstable orientations.

Plug-in Overview

Techlog Fracture Stability enables critical stress analysis of fractures or faults. The shear sliding of critically stressed fractures can result in increased hydraulic conductivity. This can cause additional pathways for hydrocarbon migration or act as channels for water breakthrough and gas coning. A better understanding of fracture mechanics and how it relates to hydraulic conductivity is essential to optimize reservoir and well performance.

Features

Techlog Fracture Stability enables the evaluation of stresses acting on fractures or faults based on their orientation and available stress-field information. The inputs can be defined either as log inputs or parameter inputs or any combination of those. The dips can derive from an image interpretation or can be created directly through wizards provided by the plug-in. For the definition of the stress field log derived principal stresses can be consumed as well as inclined stresses output from a 3D simulation (e.g. Petrel* E&P software platform or VISAGE* Geomechanics simulator). The critical stress analysis can be performed considering the effect of injection & depletion. The results will be visualized using log-view, stereonet, histogram & a custom Mohr-Plot. The Mohr-Plot is fully interactive and is also available as a standalone application.
