WebWe consider time-lapse seismic amplitude versus offset (AVO) inversion for the reservoir properties porosity and water saturation, with a focus on monitoring the evolution of water saturation in a dynamic setting of ongoing production. We operate in a Bayesian framework based on the integration of seismic AVO modeling and rock physics relations. One … Web3D and 4D seismic inversion serve as tools in the procedure of reservoir model building. In particular, inversion of 4D seismic data is aimed at delivering robust quantitative estimates of reservoir changes. Unlike 3D inversion, 4D inversion workflows face the unique uncertainties associated with data repeatability. how to say bad in cantonese
