GS offers a comprehensive range of pre-stack (AVO and inversion) and post-stack seismic attributes. These attributes are generated to derive seismic facies, particularly in areas without well control where seismic inversion is not feasible. They also complement seismic inversion results.
In the realm of sequence stratigraphy, GS is highly skilled in both seismic and well sequence stratigraphy, having conducted numerous projects in recent years. Seismic interpreters excel in deriving facies information from 2D and 3D seismic data, interpreting depositional environments including reservoir and seal distribution and quality. They can perform local and full-basin sequence interpretations to contextualize reservoirs, determining burial history, basin evolution, and depositional histories. Their work produces full chronostratigraphic sequence charts, horizon maps, well correlations, facies maps, and paleogeography maps.
Seismic inversion involves determining the features of a process by observing its effects. Specifically, it refers to determining Acoustic Impedance values (velocity times density) from seismic input, removing the wavelet, and creating models that closely resemble reality. This process translates seismic interfaces into layers, providing additional information to lower exploration risks and quantify reserves in production. GS offers a suite of seismic inversion techniques, including post-stack inversion that transforms a single seismic data volume into acoustic impedance by integrating seismic data, well data, and a basic stratigraphic interpretation, and pre-stack inversion that transforms seismic angle or offset data into P-impedance, S-impedance, and density volumes by integrating seismic angle/offset gathers, well data, and a basic stratigraphic interpretation.
