We are committed to delivering broadband data of the highest quality – ready for quantitative interpretation and tailored to suit the needs of our clients.
Realise the full potential of blended acquisition without compromising data quality or amplitude fidelity with our inversion-based deblending algorithm.
DUG’s deghosting technology: DUG Broad removes the amplitude and phase distortion caused by both source and receiver ghosts.
DUG recognises the use of high-quality relevant signatures in the effective deconvolution of the source wavelet from seismic data as an important part of high fidelity broadband processing. We use the NFH data to calculate notional signatures for every shot and subsequently use these for signature deconvolution and zero-phasing.
DUG’s interbed multiple elimination process – DUG IME – accurately models and subtracts interbed multiples. It can be used to predict the multiple model from a single generator or it can be applied in a cascaded (top-down) manner to eliminate interbed multiples resulting from a number of different generators.
DUG SW-SRME (3D shallow water surface-related multiple elimination) is our 3D multiple attenuation algorithm for shallow water settings. SW-SRME overcomes the issue of the lack of recorded near offsets using a model of the sea-bed reflection.
In addition to the standard pre-processing tools, a full suite of conditioning algorithms is available to improve the final images and prepare the gathers for AVO and QI studies.
