Expert, independent advice on the most appropriate satellite imagery (optical, radar) and elevation data products.
The benchmark for petrophysics, rock physics, facies analysis and statistical mineralogy. Collaborative multi-well log analysis made easy for better drilling decisions.
This collaborative approach is carried through to the seismic processing phase, where we iteratively apply processing parameters, testing for the best signal to noise ratio across the range of offsets at the reservoir level, and comparing the results with modeled seismic gathers at well locations. An optimal result is produced when the seismic data are rich in frequencies, relatively noise free, of consistent amplitude, and the signal events at the reservoir are aligned to the expected AVO modeled response at the reservoir.
Wide-azimuth acquisition introduces another conditioning requirement – velocity variation with angle and azimuth. CGG have developed new processing algorithms to analyze and remove these effects, providing measurements of the magnitude and direction of the anisotropy, which give an indication of the presence of fractures in the overlying strata.
Often times the seismic data at hand was not acquired and processed specifically for reservoir characterization. The seismic gathers resulting from PSTM or PSDM processing can be further high-graded to better address the additional challenges of advanced seismic techniques such as pre-stack inversion or azimuthal analysis.
When properly evaluated and applied, the result is better quantitative reservoir characterization, improved interpretation and increased confidence.
