Recent exploration activities within Paleocene and Eocene remobilized sands have proven the injectite play in the Northern Viking Graben (NVG). Wells targeting these sands have led to new discoveries such as Kveikje (2022) and Heisenberg (2023). This study proposes a robust methodology for detailed ...

Elastic full-waveform inversion (FWI) is now emerging as an industrial tool for the compressional velocity (Vp) model build, driven mainly by diving and reflected P waves. On the other hand, the inversion of S waves in elastic FWI to update shear velocity (Vs) models ...

In shallow water environments the presence of a hard water-bottom and near-surface geological complexities can give rise to strong guided-waves and other elastic effects in the recorded data. These effects can pose challenges for conventional full-waveform inversion (FWI) based on acoustic approximations, leading to ...

Geomechanical screening of potential CO2 storage sites in deep geological formations presents a substantial challenge, particularly in tectonically active regions like offshore Sarawak. In this study, we collect existing logs and downhole stress and pressure measurements to construct 1D mechanical earth models for three ...

This case study demonstrates the collaborative advantages when an Operator and a Geoscience Contractor work collectively as part of a tailor-made Integrated Virtual Asset team, to solve complex subsurface challenges in a restricted time frame. The operating challenge was to de-risk a potential drilling ...

This study focuses on mapping the lateral and vertical extent of high-quality reservoir sandstone units within the Late Jurassic Fulmar Formation, adjacent to salt interpod walls within the Shaw Field, UKCS. An integrated approach, which combined biostratigraphy, petrography, electrofacies, image log analysis and seismic ...

Mohns Ridge is currently the subject of much interest owing to the occurrence of hydrothermal vent fields and critical metal-bearing seafloor massive sulphide (SMS) deposits along this segment of the ultraslow-spreading Arctic Mid-Ocean Ridge. To target where potentially mineable SMS deposits may form or ...

Fracture characterisation is a key factor for reservoir production optimization. Velocity Variation with Azimuth (VVAz) and Amplitude Variation with Azimuth (AVAz) are the main technologies currently used in the industry for azimuthal anisotropy characterisation, whether it is fracture- or stress-induced, from PP seismic data ...

The top basement surface of the Patch Bank Ridge offers distinct morphologies that are studied in detail. We use the seismically interpreted top basement surface as our digital elevation model to analyze geomorphology and structure and discuss differences and timing of the development of ...
