Up/down deconvolution using the upgoing wavefield (left) compared to down/down deconvolution using the down-going wavefield (right). The down-going wavefield can significantly improve near-surface imaging when processed with DUG’s exclusive down/down deconvolution algorithm. (Data courtesy of Carbon Transition and TGS)
Ocean bottom geophone data are often contaminated by shear-like noise (“Vz noise”). DUG’s (patent-pending) algorithm applies a distributed compressive sensing approach called joint sparsity recovery to P and Z data to perform up/down wavefield separation and isolation of the Vz noise.

Highly efficient multi-vessel, multi-source OBS surveys are now a tried and tested reality thanks to DUG Deblend. Eliminate troublesome Vz noise with our patent-pending joint sparsity recovery approach. Harness the power of up/down deconvolution and, exclusively to DUG, down/down deconvolution to apply 3D deghosting, designature and demultiple in a single step to produce superior images with the down-going wavefield. Reap the benefits of rich azimuthal information with our advanced imaging algorithms, including Multi-parameter FWI.
