Survey design in anisotropy media from focal beam analysis

The insufficient sampling parameters will result in an acquisition footprint on time slice, low resolution, unreliable angle-dependent reflection amplitude (AVP-information), low signal to noise ratio and incorrect velocity estimation. One way to design a reliable seismic survey is through the focal beam method, where it has the advantage of analysing resolution and AVP imprint caused by incomplete acquisition design. In addition, the focal beam analysis able to determine the seismic contribution from either the receiver or the source side only. While the focal beam method is extensively used in homogeneous and heterogenous media, the application in inhomogeneous medium and extending them to anisotropy medium can increase the focal beam analysis value. © 2019 Asia Petroleum Geoscience Conference and Exhibition, APGCE 2019.
