Abstract

Seismic data from West Africa shows strong evidence of the effects of seismic anisotropy. In this paper we<br>show an estimation scheme based on the measurement of nonhyperbolic moveout. Although nonhyperbolic<br>moveout can be caused by various effects (rapid vertical or lateral velocity variations), the smoothness of the<br>velocity field, as well as the spatial consistency of the measurements, indicates that seismic anisotropy is the<br>primary cause of the moveout behaviour of this dataset.
