Method for Visualizing Multi-Component Seismic Data Including Rotational Data
The present invention provides visualization of a seismic wavefield as measured by various multi-component sensors, including, but not limited to, pressure, 3-component vector spatial pressure gradients, 3-component linear motion, and 3-component rotational motion. The visualization of the present invention employs combinations of dynamic displacement; dynamic rotation; dynamic dilation and compression; and dynamic color and transparency variations to display various measurements of a seismic wavefield. The visualization of the present invention may be applied to various seismic data sets, including, but not limited to, pre-stack data sets; post-migration data volumes; micro-seismic passive or active source monitoring; and vertical seismic profiles. The method has a wide range of application in seismic surveys in oil and gas exploration and production.
