Summary The geology of northern Oman presents significant challenges for land velocity model building. We show in this paper that these challenges can be overcome by using an integrated high-resolution velocity model workflow, through the combination

Summary Successful applications of full waveform inversion (FWI) to land datasets are far less numerous than marine applications, yet the development of dense, long-offset broadband acquisitions has presented promising opportunities. While challenges

Summary Broadband land WAZ acquisitions provide the ideal data for land FWI thanks to low frequencies and long offsets. While acoustic FWI has been successful in the north of Oman, the complex near-surface geology and the presence of strong velocity

Reverse-time migration (RTM) is the state-of-the-art imaging technology for complex structures. The most important plays nowadays in Brazil are in the pre-salt region. The complex overburden above them, with salt bodies, volcanics and/or shallow carb

Developed for the shallow channel anomalies in the North Sea, the dip constrained tomography can also be effective in subsalt areas, when geological dip constraints are known. Subsalt areas often suffer from noisy residual move-out information and li

Anisotropic parameter estimation is challenging for new exploration areas where there is no well data. In a 3000 km2 offshore survey from West Africa, we used surface seismic data in a non-linear tomographic inversion to simultaneously estimate migra

Conventional imaging does not deal adequately with absorption, especially in the case of strong anomalies. Over recent years, many authors have proposed to compensate the absorption loss effects inside of the migration through the use of an attenuati
