Geophysical Interpretations

Seismic Interpretation is the extraction of subsurface geologic information from seismic data. Interpreting seismic data requires an understanding of the subsurface formations and how they may affect wave reception. Or Seismic interpretation is the science (and art) of inferring the geology at some depth from the processed seismic record.

Our speciality is the application of structural geology to exploration and production problems. Over the years our clients have frequently called upon our expertise in seismic interpretation and structural geology to interpret structurally-complex data sets for which they do not have the in-house experts.

The Seismic Interpretation module enables basin-, prospect-, and field-scale 2D/3D seismic interpretation and mapping. You can work with thousands of 2D lines, thousands of kilometers, and multiple 3D vintages and surveys—across multiple coordinate systems with very high visualization performances (GPU based).

Advanced visualization tools enable seismic overlay and RGB/CMY color blending and enhance the delineation of structural and stratigraphic features. Accurate interpretation of those features is made possible by the complete set of tools, such as advanced horizon tracking, multi-Z interpretation, interactive mesh editing, and more. You can move effortlessly from interpretation to structural model building and back using the modeling-while-interpreting workflow.
