Abstract
A system and a method for estimating a reservoir parameter are provided. The method includes calculating a plurality of priors using a Markov random field, the plurality of priors comprising probability distributions of a plurality of litho-types; calculating posterior distributions based on the priors, the posterior distribution depending upon measured geophysical data, geophysical attributes and reservoir parameters; and determining at least a portion of litho-types in the plurality of litho-types that correlate most with the measured geophysical data.
Claims19
A method for estimating a reservoir parameter, wherein the method is implemented in a computer system comprising one or more processors configured to execute one or more computer program modules, the method comprising:
- calculating, by the one or more processors, a plurality of priors using a Markov random field, the plurality of priors comprising probability distributions of a plurality of litho-types;
- calculating, by the one or more processors, posterior distributions based on the priors, the posterior distribution depending upon measured geophysical data, geophysical attributes and reservoir parameters;
- and
- determining, by the one or more processors, at least a portion of litho-types in the plurality of litho-types that correlate most with the measured geophysical data.
