Technical Paper: Efficient Land Seismic Acquisition Sampling Using Rotational Data

Society: EAGE
Paper Number: Th ELI1 08
Presentation Date: 2014


We further investigate the benefit of a novel ground-roll attenuation method using newly available measurements of the rotational components of the wavefield. This method is based on adaptive subtraction using the rotational components as noise models. Field tests demonstrate that these noise models are significantly better than those provided by the horizontal components of conventional 3C geophone data. Because the technique is applied locally at an individual receiver station, the coherent noise attenuation performance is independent of the spatial sampling, in contrast to multi-trace velocity filtering. This approach can allow a relaxation of the field effort associated with spatial sampling to attenuate ground-roll and therefore impact overall acquisition costs.
