METHOD TO CHARACTERIZE GEOLOGICAL FORMATIONS USING SECONDARY SOURCE SEISMIC DATA

摘要

A method for determining an elastic property of a geological formation, such as Thomsen parameter delta, is described herein. The method includes identifying a secondary Sv-wave and its associated arrival time within seismic data obtained from an array of seismic receivers. An elastic property of the geological formation is determined using the associated arrival time of the secondary Sv-wave.
