Oil companies face many challenges in mature basins such as the UK Southern North Sea (UK-SNS) while seeking to optimize their exploration and production efforts along with growing environmental regulations and commitments to reduce carbon emissions. Utilizing rejuvenated regional 3D seismic data libraries provides a cost-effective and scalable data source fit for both near field exploration and Carbon Capture and Storage (CCS) projects. This study aims to address these challenges by utilizing multi-survey vintages reprocessing and modern geosciences techniques to enhance seismic imaging quality from shallow to deep, unlock new hydrocarbon prospects, improve interpretation and assist evaluating CCS site(s) and reservoir development potential. High quality seismic data are an essential foundation for these energy projects. 26 Legacy seismic data sets (acquired between 1988 – 2006) have been reprocessed and are being delivered by the time of this workshop.
To complement this effort a complete regional interpretation and seismic reservoir characterisation (including regional rock physics, seismic inversion and reservoir properties transform) have been performed representing a regional screening product of around 12 000 sqkm available for CCS site selection, characterization and near-field exploration. This case study will demonstrate that an integrated geoscience approach can have a dual benefit for the energy security and transition challenges we are facing today.
