Abstract

CCS is an efficient and an inevitable way to tackle climate crisis. Denmark aims at carbon neutrality by exploring and utilizing potential storage sites for CO2 sequestration. A series of upscaled high-resolution reflection seismic surveys have been planned and are currently being carried out across the country to investigate potential reservoir sites; the largest one being around the town of Gassum and targeting the reservoir sandstones of the Gassum Formation. A dual element recording system has been adapted and spaced MEMs-based recorder on a moving landstreamer system. Here, we present the longest profile of the Gassum survey, P9, from the nodal array. Given the long offset range of the nodal arrays and high-quality data acquired, we aim at employing various velocity model building approaches to characterize the Gassum structure and its four-way closure or domed-shaped structure. Preliminary processing work reveals the domed Gassum structure with quality. Future works in the velocity model employing traveltime tomography and full-waveform inversion would help to further improve the quality of the sections and better characterize the target reservoir.
