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 ...

The Early Cretaceous sands on the Måløy slope constitute as reservoir for many oil and gas discoveries as seen in the Duva field and Hamlet and Ofelia discoveries. These sands have been deposited in submarine channels and fans, fed by material derived from the ...

Full-waveform inversion (FWI) uses the full wavefield as input but, in general, diving waves are the key driver of the method. How to maximize the contribution of reflected waves is an important factor for success of FWI, especially on seismic data with a short ...

We present AI-drive workflow for automatic interpretation of large seismic volumes. The workflow is applied to an offshore Abu Dhabi area of 15000 km2. First, we show the fault detection results for the low-magnitude faults of strike-slip type by the fine-tuning of the DNN.

Since the discovery of pre-salt oil fields offshore Brazil two decades ago, the Santos Basin has transitioned from an exploratory to a development phase. This requires a more comprehensive understanding of the reservoir physical properties. This study aims to demonstrate, on one of the ...
