CCED is the operator of onshore blocks in the Sultanate of Oman. The blocks are located on the eastern flank of the Oman Salt Basin. Within the area of interest, the Barik, Al Bashair, Buah and Khufai Formations form the main oil and gas ...

Tables are ubiquitous in the geoscience industry, appearing in numerous documents and spreadsheets. They contain a wealth of data in a structured format which can help us understand the subsurface. However, the number of tables created over the years is huge and it requires ...

Novel/Additive Information: The paper presents a simple and computational fast method to predict CO2 injectivity and well pressure as a function of time. The application of superposition in time - a method usually associated with solving linear problems - is demonstrated to adequately solve ...

Up-down deconvolution remains a powerful tool for the processing of ocean-bottom node data through its ability to efficiently attenuate free-surface multiples along with the source ghost and signature. Practical receiver-domain implementations in the frequency-wavenumber domain, however, assume layer-cake geology and can leave residual multiples ...

Recent advances in full-waveform inversion (FWI) algorithms have allowed it to work stably and effectively in different geological settings, especially in areas with geobodies of large impedance contrasts such as salt, despite its presently taken acoustic assumption. This has resulted in a leap in ...

Full-waveform inversion (FWI) has become the norm in velocity model building for different surveys from land to marine, and from streamers to ocean bottom nodes. FWI using wide-azimuth (WAZ) streamer data in areas with complex geologic settings can fall short of resolving the complexity ...

Most seismic surveys carried out in offshore Brazil consist of narrow-azimuth towed-streamer (NATS) acquisitions. In areas such as the South Atlantic offshore basins, the geological complexity results in illumination issues for NATS acquisitions, especially in the deep pre-salt section. Both Full-Waveform Inversion Imaging (FWI ...

Recent technology advancements have enabled us to revisit the Foz do Amazonas (2014) and Barreirinhas (2016) narrow-azimuth towed-streamer (NATS) seismic surveys and tackle specific imaging challenges in a way that the legacy processing could not. In an exploratory frontier such as the Brazilian Equatorial ...

Monument field is located in the northwest part of Walker Ridge in the Gulf of Mexico, with a Paleogene sandstone reservoir ?9 km below sea surface. The complicated overburden of low reflectivity shale bodies and complex salt geometries with steep salt flanks, multi-level weld ...
