MWD

We have developed a model-based water-layer demultiple (MWD) technique specifically designed to attenuate multiples in shallow water. This technique is similar to Surface Related Multiple Elimination (SRME) which has become the de facto standard for marine demultiple.  Read more...


TSKK Footprint Attenuation

Most acquisition geometries have regularly spaced source lines and receiver lines. This regular spacing (or sampling) can lead to periodic amplitude striping that mimics the source line and receiver line intervals. This periodic amplitude striping is called an “Acquisition Footprint”. Surface consistent shot and receiver scaling cannot compensate for this amplitude banding, as it is a function of the offset distribution. The amplitude banding can be subtle when viewed in a section view, b  Read more...


VVAZ

We perform Velocity Variation with AZimuth (VVAZ) analysis to estimate and correct for azimuthal velocity variations. One cause of azimuthal velocity variations is the presence of horizontal transverse isotropic (HTI) media.   Read more...
