Automatic clustering of constituent faults into a single surface is accomplished with the Planar Clustering feature (licensed separately), which allows the user to select which faults may potentially be clustered together.VoxelGeo™ automatic mode display of lineament volumes quickly shows the entire fault complex, prior to possible fault linkage problems.A new seismic attribute volume of the extracted lineaments is also available for further study. Rose diagrams allow independent statistical analysis of automatically extracted lineaments, for the study of fractured plays.Enhanced discontinuity attribute volumes are available for both the automated extraction process and for assisting manual structural interpretation.Faults are named according to their strike and dip, allowing the interpreter to easily select, manipulate, display and analyze structural orientations.

Faults split into separate extracted faults are usually split because of a geologic change, prompting the geoscientist to evaluate the reason for the break rather than forcing manual picks from line to line.Rose diagram analyses and faults selected and displayed relative to calibrated structural horizons enable interpreters to quickly decipher complicated structural history.Fast extraction of hundreds of faults allows interpreters to concentrate on geological history rather than on the tedious picking process.User has full parameter control at every step of the process.Improved horizon autotracking, making use of interpreted fault surfaces as constraints.Consistent and accurate interpretation of 3D fault surfaces.Reduced cycle time for fault surface interpretation.These surfaces can also be used to help constrain and improve the performance of auto-tracking and segmentation algorithms, minimizing problems with miscorrelation across faults in the data. FaultTrak can be used as part of the interactive fault picking process, or the user can choose to run it as a batch operation.Įmerson's Automatic Fault Extraction (AFE), under license from Terraspark Geosciences, both automates and enhances the process of identifying, extracting and modeling geologic discontinuities such as faults, from subsurface seismic volumes.

The semi-automatic, user-driven FaultTrak™ tool facilitates interpretation of surveys containing complex faulting with minimal manual effort. Emerson E&P Software offers a choice of semi-automatic and automatic tools for fault tracking and fault extraction.
