Abstract (AI)
In this work we present a method for CO2 plume detection that is based on refraction tomography of sparse seismic data recorded by surface distributed acoustic sensing (S-DAS) cables deployed on the seafloor. The workflow is demonstrated using a synthetic dataset modeled from a southern North Sea analogue and three different survey layouts with a decreasing number of receivers.
Key Findings
1
A CO2 plume detection method is presented based on refraction tomography of sparse surface DAS (S-DAS) seismic data recorded on the seafloor.
2
The method is applicable to S-DAS cable deployments on the seafloor for CO2 plume monitoring in marine settings.
3
The proposed workflow is demonstrated using a synthetic dataset modeled from a southern North Sea analogue.
4
Three different survey layouts with decreasing numbers of receivers were evaluated to test detection with sparse receiver distributions.
