In areas of complex geology, strong impedance contrasts can generate highly elastic behavior leading to the breakdown of the acoustic assumption in FWI. In these cases, accurate Earth models cannot be obtained without considering the elastic wave equation. Many previous studies of elastic FWI ...

This paper demonstrates how generative artificial intelligence (AI) enhances geoscientific document processing by improving text analysis, table extraction, and figure classification.

This paper highlights recent progress and breakthroughs in land FWI with two examples from the Sultanate of Oman (one from the north and one from the south).

Brazilian pre-salt often exhibits geologically complex settings with many challenges for oil and gas exploration and production. One of these key challenges is the presence of igneous rocks. We analyze the ability of full-waveform inversion (FWI) to identify and detect this class of rock ...

Full waveform inversion (FWI) is becoming an increasingly dominant force in velocity model building and seismic imaging, often providing us with unrivaled focusing and resolution of the subsurface image. The superior velocity models and seismic images achieved through FWI also enable serious and more ...

Land seismic data in the Sultanate of Oman presents more and different challenges for full-waveform inversion (FWI) compared to marine data. This is mainly due to complex near-surface effects that create strong ground roll, which obscures already poor data quality, especially at lower frequencies ...

Full-waveform inversion (FWI) has demonstrated tremendous potential to provide high-resolution subsurface models. However, obtaining an accurate FWI velocity model can still be challenging in steep continental slope shelf geologic environments. The uncertainties, often caused by shallow abrupt velocity contrasts, limited diving-wave penetration depth, and ...

Historically, Brazilian pre-salt fields have been imaged by narrow-azimuth towed-streamer (NATS) data. More recently, ocean bottom node (OBN) acquisitions have been employed to image and monitor already producing fields. In cases as such, 4D seismic monitoring is only possible via NATS/OBN hybrid pairs, where ...
