SPECTRA GEOPHYSICAL AS
Our frequency-dependent workflows significantly help to de-risking already identified exploration prospects or identifying new prospects. Our confidence is based on testing our workflows on 3D seismic data over various oil & gas discoveries and dry wells. These frequency-dependent workflows can be implemented in different stages, e.g., exploration of new prospects or development of mature fields.
We require angle stacked offset data to perform Quantitative Interpretation (QI) frequency-dependent processing. Right after doing conventional AVO Analysis on full band offset 3D seismic data, we perform frequency-dependent QI Workflow analysis for Fluid Factor and eventually HC Phase prediction based on Intercept Vs Gradient crossplots from decomposed frequencies.
Our Colour Blended volume based on our frequency workflows from frequency decomposition of low-frequency enhanced processed seismic data are so wonderful in relation to hydrocarbon presence.
The bright frequency anomalies due to reservoir presence clearly stand out from non-reservoir darker zones. Our Frequency-dependent QI Workflow identifies not only reservoir zones of good quality but also non-reservoir zone within the structural closure of the reservoir. So in the development fields, our workflow processed data would help in-filling drilling wells and areas to avoid even within the reservoir closure.
Any exploration prospects supported by our frequency workflows would suggest higher probability of success. Contrarily, any prospect not supported by our frequency processing would have lower probability of success. The probability of success will be so high when our two of the workflows matching with each other!
