Efficient 3-D wavefield extrapolation with Fourier finite-differences and helical boundary conditions

Abstract

Fourier finite-difference (FFD) migration combines the complementary advantages of the phase-shift and finite-difference migration methods. However, as with other implicit finite-difference algorithms, direct application to 3-D problems is prohibitively expensive. Rather than making the simple x y splitting approximation that leads to extensive azimuthal… (More)
