Abstract

Azimuthal velocity and AVO analyses aimed at detection of azimuthally aligned fracturing became common practice nowadays. Yet, together these technique are used not so often. Even less common is implementation of seismic-based geomechanical modeling. Here we discuss specific features and results of all the three techniques applied to 3-D data from an oil field in West Siberia to detect HTI anisotropy in the target interval. Conceptually, all three techniques are capable of providing independent estimates at every bin, while vertical resolution is substantially different: velocity analysis successfully measures integral effect over rather thick intervals, AVO reflects differential effect, while vertical resolution of GM predictions is about the same as that of seismic amplitude inversion. This makes the three techniques fruitfully complementing each other, as is shown in the case study presented.
