This course provides a unified value-proposition approach that fills a critical skills gap by teaching participants PS-waves are routinely acquired on land and the seabed with nodes, but sit unused on the shelf. This technology is always new because shear waves constantly play catch-up with P-wave advancements. The goal of this course is to bring PS-waves into the main stream of reservoir exploration and production. This course distinguishes the fundamental properties of PS-waves from P-waves: polarization (S-wave splitting), illumination, amplitude, and velocity anisotropy. The course includes basics of PS-wave acquisition and processing, and challenges of velocity model building and prestack migration. Many examples show the benefits of joint PS- and P-wave AVO inversion for reservoir properties: facies, lithology, fracture identification, pressure prediction, and production monitoring.
