Abstract

The gradients of the bottom hole pressure with respect to reservoir characteristics to be identified are required by all history matching processes. A method for computing gradients related to lithofacies is described. The effects of a lithofacies on well pressure or production history are analyzed using a geological model derived from seismic interpretation or object-based geostatistical simulation. By introducing gradients to minimize an objective function that measures the difference between observed and simulated well responses, the inversion of petrophysical lithofacies parameter can be effectively undertaken.
