Seismic Geometric
Decomposition Plugin

  • Seismic Geometric Decomposition (SGD) Plugin for Petrel Helps to minimize risk and reduce uncertainty by improving the delineation of the Fault System, the external and internal reservoir architecture.
  • The SGD Volumes recover the internal geometry variations of the original seismic reflectors generating higher detail, enhancing subtle faulting and helping to visualize unnoticed features.
  • Standard interpretation workflows for Structural and Stratigraphic analysis can be applied to the SGD volumes to improve reservoir understanding. The Fault Enhancement and Reservoir compartmentalization mapping products offered by Cayros Solutions are some examples of this extended applicability.

Seismic Geometric Decomposition Software

The Seismic Geometric Decomposition Plugin for Petrel is a tool designed to generate a series of high definition seismic volumes that can be used to improve the delineation of the Fault System, the external and internal reservoir architecture and to recognize reflectivity patterns for geomorphology analysis.

SGD plugin for Petrel delivers a product with higher internal details and continuity of the reflectors than the original seismic, facilitating the interpretation of complex structures.

Along with the rest of the knowledge base SGD volumes can be of help to delineate those subtle details that are not described by the original seismic and could explain production uncertainties.

Consulting Services

Fault Enhancement and Reservoir compartmentalization mapping  are some of the services offered by Cayros Solutions that take advantage of the Seismic Geometric Decomposition volumes generated by the plugin.

In the example presented to the right, the drilling cost was very high and several issues occurred while drilling along faulted zones. The use of the segmentation maps generated successfully helped reducing the risk when positioning new wells.

Seismic Geometric Decomposition Lower
The images above show the segmentation and compartmentalization for a natural fractured carbonate reservoir (Jurassic). The process applied to the original seismic (left) fails to properly delineate the complex fault  setting of the field. Same workflow and parameterization is applied to SGD seismic version (right)   improving the understanding of the segmentation within the window of interest.
