WebFull-wavefield seismic inversion (FWI) estimates a subsurface elastic model by iteratively minimizing the difference between observed and simulated data. This process is extremely computationally intensive, with a cost comparable to at least hundreds of prestack reverse-time depth migrations. When FWI is applied using explicit time-domain or frequency … WebIn the past, seismic exploration was used primarily to search for structural traps, but with the advances in seismic acquisition, processing technology, and computer technology, seismic exploration is increasingly used for hydrocarbon detection. Identifying hydrocarbon reservoirs directly on the seismic section has been our goal for many years.
