Accommodate a range of geological settings and acquisition geometries with flexible, amplitude-preserving implementation.
Advanced data interpretation for underexplored continental margin
Using inversion of seismic amplitude data, seismic AVO attributes, AVO modeling, and well data integration techniques, our petrotechnical experts are able to estimate acoustic and elastic rock properties, that are related to reservoir properties including porosity, lithology, saturation, stress, and pore pressure. These results are used to screen or evaluate prospects, optimize borehole orientation, explain and predict well behavior, and populate static reservoir models.

The simultaneous seismic inversion delivers a breakthrough in the analysis and interpretation of AVO seismic data. Partial stacks can be inverted directly for high-resolution acoustic impedance, Vp/Vs or shear impedance, and density. From these physical properties, lithology, fluid, and other rock properties may be predicted.
An analysis of AVO attributes from seismic gathers, plus attributes from AVO inversion, will permit a clearer identification of exploratory leads.
