Eni has let a contract to Shearwater GeoServices Holding AS for a 3D multiple technology integrated geophysical survey, with an option for a second survey, for use carbon storage in Liverpool Bay, England (HyNet North West project).
The surveys will involve both bathymetric and 3D seismic surveys, to give high-resolution imaging of the overburden, as well as high-resolution data for analysis of the seabed and shallow geology. A specialized shallow water seismic node crew will be used for operations in the shallow water areas.
The first survey is over Hamilton and North Hamilton fields, and the optional survey is over Lennox field. The fields are covered by a carbon dioxide (CO2) appraisal and storage license, where Eni intends to reuse and repurpose depleted hydrocarbon reservoirs and associated infrastructure to permanently store CO2 emissions captured from pre-existing local industries and the future production sites of low carbon hydrogen in the industrial district of NW England and N Wales (OGJ Online, Feb. 9, 2022).
Storage operations are expected to begin in 2025. Initial capacity of 4.5 million tonnes/year (tpy) of CO2 is expected, with a possibility to extend to 10 million tpy by 2030, according to Eni.
The surveys will be led by the SW Bly, with each survey taking just under 1-month to complete.
HyNet North West is promoted and developed by a multi-partner consortium which Eni leads through Eni UK, together with Progressive Energy, Cadent, CF Fertilisers, Essar, Hanson, INOVYN (part of INEOS Group) and the University of Chester.
