Device and method for deghosting P-waves

摘要

Computing device and method for determining primary and ghost components from recorded P-waves. The method includes receiving seismic data (R, V) with regard to the P-waves, wherein the seismic data includes vertical and radial components recorded with a buried two-component receiver; calculating with a processor a primary component (P) and a ghost component (G) from the vertical and radial components; and computing an image of a subsurface based on the primary and ghost components (P, G). The P-waves form a plane wave.
