The traditional seismic processing and imaging workflow has been around for decades.
It involves the testing and application of dozens of processing steps such as deghosting, designature, demultiple and regularisation, which are all designed to overcome the restrictions of conventional imaging algorithms. These workflows can be complex, subjective, and very time-consuming due to their serial nature and they often rely on many assumptions and simplifications which require further steps to resolve. All of these issues can impact the output data quality. The resulting, primary-only data then undergoes a similarly complex model-building workflow to derive an estimate of the subsurface velocity. This treatment of seismic data means that projects can take many months or even years to complete.
DUG Multi-parameter FWI Imaging is a new and unique approach to seismic processing and imaging which turns this traditional paradigm on its head. Our innovative implementation of full waveform inversion (FWI) achieves simultaneous model-building and full-wavefield least-squares depth imaging directly from field data, without the need for the traditional processing workflow and its various assumptions.
It is now possible to determine a wide range of Earth parameters including attenuation, anisotropic velocity and true-amplitude three-component reflectivity using multi-parameter FWI. The more complete physics of DUG MP-FWI Imaging naturally allows parts of the data traditionally considered as noise, and therefore attenuated during pre-processing, to be retained and treated as valuable signal. Using primary reflections, as well as all forms of multiples and ghosts, guarantees significantly better subsurface sampling, which in turn provides much-improved illumination and resolution over conventional, primary-only imaging.
DUG’s approach provides reflectivity images that can be used for both structural and quantitative interpretation including pre-stack outputs for AVA and elastic rock property analysis. When using the full wavefield for simultaneous velocity model building and true-amplitude imaging a multi-parameter inversion is a necessity. A single-parameter FWI cannot separate velocity and reflectivity with validity.
DUG MP-FWI Imaging uses superior physics to get the most out of the recorded data, delivering unsurpassed imaging with rapid turnaround. It is a complete replacement for the traditional processing and imaging workflow. This is the new standard for seismic processing and imaging, and the future is exciting.
