Fault Seal Analysis
We use stress field knowledge with fault mapping from seismic data to understand reservoir compartmentalization for improved production.
Stress state drives the ability of reservoir-bounding faults to serve as effective fault seals. If the faults are critically stressed, repeated slip will reduce sealing properties, causing hydrocarbon leakage and limiting maximum column height. We can help you qualify fault leakage probability with reservoir geomechanics.
Understanding stress helps you understand seal stress and pore-pressure control fault reactivation. Since reactivated faults tend to be permeable, stresses resolved on faults can control fault seal integrity, hydrocarbon migration, reservoir compartmentalization, and maximum hydrocarbon column heights.
We start with accurate knowledge of reservoir in-situ stress orientation and magnitudes using our software and/or seismic data. We analyze seismically mapped fault segments with our MohrFracs™ application to determine fault proximity to frictional failure, allowing us to reduce guesswork and increase your production capabilities.
