About Us

In addition to accurate structural images of their targets, interpreters today require well conditioned gathers ready for further attribute analyses. Sensor Seismic Solutions Ltd. has evolved a set of tools and methodologies designed to deliver these.

Obtaining adequate noise attenuation while preserving signal amplitudes is achieved by iteratively attacking noise throughout the processing sequence. We’ve successfully attenuated noise found on uncorrelated and unsummed Vibroseis field records, on common source and common receiver gathers before and after deconvolution, on azimuth sectored common midpoint gathers (or, for converted wave data, on common conversion point gathers) and on regularized natural and 5D interpolated common offset vector gathers, both before and after migration. Methods for attenuating both coherent forms of noise, like surface wave energy and multiple reflections, and unorganized environmental and cultural noise have been developed.

We have the technology for estimating and applying surface or midpoint consistent scaling and waveform corrections as well as the surface consistent static shifts and travel time corrections. This includes corrections for the variation of velocities with source to receiver azimuths (VVAz) required to produce gathers suitable for further study.

We also have the tools required to address the complications arising from the asymmetric nature of converted wave ray paths, both when performing early moveout corrections, and later when prestack migrating the converted wave data. Additional methods for verifying the way that 3C receivers were oriented in the field all the way to analyzing and correcting for shear wave splitting effects and for performing depth variant common conversion point binning in the side flows leading up to a full prestack migration are also available to us.

Sensor also has considerable experience using the tools and techniques required for merging 3D datasets of different vintage, and for 4D processing. We know when processes should be applied independently to the different volumes in your time lapse surveys, and when a common set of corrections must be applied to all of the surveys, and we have developed tools for cross-equalizing datasets, for compensating for different acquisition geometries and for matching the fold of surveys that have not been specifically acquired as repeats.

Finally, our technology is complemented by the pride that we take in our work. We sincerely wish to provide your team with solutions that can help improve its understanding of the targets that interest it.
