We present the main results of a tailored velocity model building workflow on a recent broadband survey from North Kuwait. Depth imaging in Kuwait presents several challenges, including the need to capture the strong velocity variations of a complex near surface that generates long ...

Applications of full-waveform inversion (FWI) to land data have proven much more challenging than to marine data. The difficulties are linked to a lower signal-to-noise ratio but also to a greater influ-ence of elastic wave phenomena in these data sets, especially those characterized by ...

Fizz gas detection is a critical step in field development as it is often difficult to differentiate it from commercial gas in reservoirs on acquired seismic data. In a shallow reservoir context, it is theoretically possible to observe a fizz gas effect through a ...

The Haugaland High, in the Norwegian North Sea, consists of a layered overburden of sub-horizontal sediments of almost 2km thick which sits on the Cretaceous Chalk. The background velocity regime of these top layers has a low vertical gradient down to the Chalk interface ...

This study aimed to provide greater insight into the question of whether a near-field Paleozoic interval could retain sufficient reservoir quality to be attractive for future exploration. To meet this challenge, an integrated multidisciplinary approach was adopted that brought together detailed geological analysis with ...

To improve the imaging of the Barents Sea’s Nordkapp basin, either in terms of resolution or geological structure, a new seismic acquisition design was proposed, using a widespread hexa-source sitting on top of 18 non-flat streamers. Imaging this new recorded data required specific and ...

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 ...
