Onshore Processing 2D/3D/4D
Land seismic data processing techniques are divided into two distinct approaches, stratigraphic and structural, and require varying techniques and experience in order to reach the ultimate goal of creating the best image possible. Absolute Imaging specializes in AVO processing and has written proprietary algorithms to ensure data is amplitude friendly for additional inversion and reservoir characterization work.
Stratigraphic
Reservoir delineation in stratigraphic plays can be subtle and detailed processing work is needed to mitigate risk. Robust surface consistent deconvolution routines are utilized to increase the frequency content of the data and provide phase stability. Powerful noise suppression techniques for both organized and random noise help uncover the underlying signal. When tieing various vintages of 2D lines or 3D volumes, accurate phase and static tieing is accomplished allowing mapping of thin horizons across a prospect. Our goal is to create seismic data that is well imaged, honours the true phase and amplitudes while extending the bandwidth in a geologically correct manner.
Structural
Tectonically complex areas often have a complicated near surface, a structurally complex subsurface and generally poor signal to noise. Therefore, processing of this data requires specific experience and a diverse set of robust algorithms such as full featured velocity analysis tools; tomographic near surface static solutions; linear, random and erratic noise suppression techniques along with robust time and depth imaging tools. Our goal is to create a seismic section that has excellent S/N while maintaining structural integrity.
