Fracture detect result for reflection surface in shale layer
Lineaments on 4th orthogonal component have very good correlation with microseismic events and can be used like fracture detection attribute in future fracture modeling.
Plug-in Overview
The Fracture Detect plug-in identifies fractures and faults which other algorithms don’t. This works in noisy conditions, removing the noise or footprint to produce a fault and fracture attribute. The idea of this method is the decomposition of the seismic cube or reflection surface on the orthogonal components (principal components) based on its 3D or 2D autocorrelation function.
Specifications
Features
The technology can be applied to unconventional reservoirs for the detection of fracture corridors in shales or carbonates. It performs when the signal is poor and with strong noise conditions, it is ideal for deep water and sub salt exploration. Results orthogonal cubes can be used like input to Ant Tracking what is allow getting more stable results.
