SEISMIC METHODS AND SYSTEMS EMPLOYING SHALLOW SHEAR-WAVE SPLITTING ANALYSIS USING RECEIVER FUNCTIONS

摘要

Methods and systems for shallow shear-wave splitting analysis usingreceiver functions of seismic data are described. Radial and transversereceiverfunctions are calculating by, for example, performing cross-correlations ofverticalcomponent data with radial component data and vertical component data withtransverse component data, respectively. The receiver functions are then usedto determine orientation and other characteristics associated with shear wavespassing through an azimuthally anisotropic layer.
