The Cornerstone OBN survey has unquestionably brought a step-change in image quality compared to towed-streamer acquisition, especially for deeper, sub-BCU reservoirs and around salt diapirs where reservoir units are often heavily faulted and steeply-dipping. It will allow for the effective development and monitoring of ...

A machine learning pipeline for document extraction
A machine learning pipeline for document extraction
Each year the geoscience industry creates huge volumes of documents containing a wealth of knowledge which cannot be easily queried or extracted. Key to the successful extraction and transformation of data is an understanding of the nature of the data that exists within a ...
Nordkapp TopSeis/node acquisition - Lessons from a modelling study
Nordkapp TopSeis/node acquisition - Lessons from a modelling study
Based on an extensive 3D modelling study utilising full-wavefield Finite-Difference modelling and Full-Waveform Inversion (FWI) we demonstrate that the TopSeis/OBN hybrid acquisition acquired from May to August 2021 in the Nordkapp basin in the Barents Sea has the potential to image salt flanks and ...
Value of Geoscience for Carbon Capture, Storage and Utilization
Value of Geoscience for Carbon Capture, Storage and Utilization
While significant progress has been made in CCUS over the last five years, the industrial and financial sectors need to see how projects are being effectively de-risked. By capitalizing on the latest technology advances and the integration of multidisciplinary skills and data, geoscience has ...
The value of very low frequencies and far offsets for seismic data in the Permian Basin: Case study on a new dense survey from the Central Basin Platform
The value of very low frequencies and far offsets for seismic data in the Permian Basin: Case study on a new dense survey from the Central Basin Platform
This paper describes a new dense survey acquired in 2020 in the Permian Basin and aims to objectively assess the quality and benefits brought by a richer low end of the spectrum and far offsets. For this purpose, we considered several aspects, from acquisition ...
