We present a sampling free probabilistic inversion of latent target property based on the principles expectation propagation where we estimate joint distribution variable in local region. The prior model matches focused region but integrates out parameters outside focus using approximate distributions. includes large spatial structure information while maintaining dimension small. In addition, ...

For optimal hydrocarbon recovery from fractured reservoirs, a critical issue is to gain an accurate understanding of the natural fracture system. Currently, fracture characterization using amplitude based technologies is routinely performed relying on amplitude versus angle/offset (AVA/AVO) and azimuth (AVAZ) to exploit anisotropic gradient behavior, which is today commonly used in the industry...
