Up/down deconvolution (UDD) represents a concise but powerful seismic processing tool, which effectively eliminates free-surface multiples requiring little knowledge about the subsurface. While bringing significant success in ocean bottom seismic (OBS) projects, the applications of UDD on conventional towed-streamer data are often …

Summary Processing of ocean-bottom seismic data by deconvolution of up-down separated wavefields simplifies and improves seismic processing workflows because it attenuates surface-related multiples, compensates for spatio-temporal variations of the water velocity, and performs source designature and deghosting all in a single step. …

Summary Addressing climate change and achieving sustainable energy solutions demands a significant scale-up in renewable energy installations, such as large wind farms consisting of multiple wind turbines, while minimizing their environmental impact. However, constructing wind farms requires substantial resources, leading to significant …

Summary The increase in the size and number of offshore windfarm license block areas requires a review of the effiency of near-surface characterisation workflows. The size of area requiring near-surface characterisation in support of the development of offshore windfarms has increased by …

Abstract Processing of ocean-bottom seismic (OBS) data by deconvolution of up-down separated wavefields simplifies and improves 3D and 4D seismic processing workflows because it attenuates surface-related multiples, compensates for spatio-temporal variations of the water velocity, and performs source designature and deghosting. The …

Summary Distributed acoustic sensing (DAS) technology offers a wide range of applications in geophysics. In the oil and gas industry, the use of DAS is well established in the borehole domain, but it is only in the last few years that the …

Summary Multidimensional deconvolution overcomes the challenges of the up-down deconvolution process to produce optimal Green’s function on a seafloor with topography and sharp lateral variations. The multidimensional deconvolution process, solved using the inversion-based sparsity or low-rank-based optimization framework, as compared to the …

Summary Multidimensional deconvolution can be used to predict free-surface multiples in ocean-bottom seismic without assumptions on the Earth’s dimensionality, but this comes with requirements and costs. The main requirement consists of an adequate sampling of the downgoing wavefield at the receiver surface. …
