Abstract

In 2022, bp and TGS acquired a wide-tow quad source 3D High Density (3DHD) streamer survey over the Endurance carbon store in licence CS001 and the prospective stores within the CS006 licence. An efficient widetow 3D configuration was used to obtain high resolution imaging for overburden integrity and reservoir characterization. The survey successfully delivered much higher near-offset fold than legacy hydrocarbon-focused surveys, improving imaging and resolution at all geological levels.  

In 2025, bp and TGS, acquired the second 3DHD survey over Carbon Storage licence CS007. This paper outlines how this novel style of wide-tow quad-source acquisition has evolved from the 2022 to the 2025 configuration, details the relevant technical elements for large-scale 3DHD surveys, and suggests areas for future advancements.
