Abstract
Summary
Prestack AVO inversion is a key technology in hydrocarbon description, and Russell fluid factor plays an important role in pore fluid prediction. Based on porous media theory, this paper deduces a new high-order Russell fluid factor approximation to improve inversion accuracy. A linear iteration method is then applied to realize nonlinear inversion and zero-delay mutual correlation is utilized as the objective function to enhance the anti-noise capability. The inversion for Russell fluid factor is formulated in a Bayesian framework. Synthetic and real data examples demonstrate the high accuracy and stability of the proposed inversion method.
