Quantification and correction of the Thomsen’s Delta Anisotropy for improved quantitative seismic interpretation in “AMFO” Field, Western Niger Delta

The Niger Delta is a sedimentary deposit with continuing sediment deposition to date. In a stratified earth, seismic waves tend to propagate faster along layers than across layer boundaries. Shales, due to the clay minerals they contain, exhibit similar behavior. As a result, velocities derived from surface seismic are often faster than well-derived velocities, causing depths of structures from surface seismic...
