Earth modeling plays a decisive role in seismic imaging. Presently, methods such as tomography and full-waveform inversion (FWI) are widely used to generate 3D high-resolution velocity models across sedimentary basins. However, given the nonunique na

We developed an integrated method that can better constrain subsalt tomography using geology, thermal history modeling, and rock-physics principles. This method, called rock-physics-guided velocity modeling for migration uses predicted pore pressure

In the past decade, marine seismic acquisition has evolved from narrow-azimuth (NAZ) to wide-azimuth (WAZ) geometries toward the latest offering of long-offset full-azimuth (FAZ) surveys with slanted cables. This broadband long-offset acquisition des

Full-waveform inversion (FWI) has proved itself as a valuable tool for updating and improving the accuracy of subsurface velocity models. For optimum performance, particularly in complex geological environments such as subsalt targets in the Gulf of

The conventional FWI is exposed to cycle skipping especially when the initial model is inadequate and the ultra-low frequencies are not present in the observed data. If the FWI does not have the power to mitigate the cycle skipping then initial veloc

The recently introduced method of wide-azimuth data acquisition offers better illumination, noise attenuation, and lower frequencies to more accurately determine a velocity field for imaging. For the field data experiment to demonstrate the technolog

Exploration in more geologically complex areas requires new methodologies. In its quest to answer these new challenges, the oil and gas industry has moved from ray-based imaging to finite-difference, wave-equation migration to achieve better subsurfa

Wide-azimuth (WAZ) towed-streamer acquisition has improv-ed the quality and reliability of subsalt imaging in the Gulf of Mexico, where WAZ surveys have typically been ac-quired using 3–4 seismic vessels, each shooting in straight parallel lines. H

Is the salt winning? This was the question Paul Singer of Total posed at the subsalt workshop held at the Colorado School of Mines in the summer of 2005. This workshop was unique in that presenters from oil companies and contractors discussed their i
