Innovative Modeling Techniques for 2D and 3D Seismic Data
Static seismic inversion uses inverse modeling techniques to solve for acoustic and elastic rock properties from 2D and 3D seismic data. The Seismic Reservoir Characterization team has a range of AVO and inverse modeling techniques. These include prior model building, wavelet processing methods, poststack inversion, AVO inversion, and the preferred method of prestack simultaneous AVO inversion from the ISIS suite of reservoir characterization technology. Static inversion also runs on multicomponent, wide, rich, and multiazimuth seismic surveys. Products from static seismic inversion include acoustic and elastic impedance cubes; compressional velocity, shear velocity, and density cubes; and a wide range of associated seismic attributes.
Our proprietary ISIS simultaneous inversion technique provides high-resolution acoustic impedance data, Poisson's ratio data, and density cubes. It delivers a higher resolution, a more stable solution, and less noise than conventional AVO inversion techniques.
Related to static inversion are the following:
Elastic impedance modeling and inversion from angle band cubes.
