Inversion of walkaway VSP data in the presence of lateral velocity heterogeneity
Vladimir Grechka, Ilya Tsvankin, Pedro Contreras
Multi-azimuth walkaway vertical seismic profiling (VSP) is an established technique for the estimation of in situ slowness surfaces and inferring anisotropy parameters. Normally, t…
