Abstract
Carbon capture and storage has been a necessity for reducing the global carbon emissions to net zero by 2050. Assessment of geological carbon storage fields is playing a key role in projections on action scenarios. North Sea is one of the most promising areas for CCS with its large prolific saline aquifers reaching the storage capacities of megatons and vast database of exploration and production database. The aim of this study is describing a potential gas and carbon storage field situated to the Northeast of Zulu Øst field on the Patch Bank Ridge in the Norwegian North Sea using seismic facies analysis. The seal and reservoir units in the northern lobe are identified and compared with Zulu Øst Field in terms of seismic facies and thickness. Depth of the northern lobe’s crest is deeper than 800 m. below sea level, which is on the limit for safe subsurface storage of supercritical CO2. Therefore, it can be a good option for CCS development when it is compared with the Zulu Øst field’s crest depth (770 m). Skade formation sands are also suitable reservoirs for both lobes with their depths and thicknesses.
