Method for estimating or simulating parameters of a stratum structure

摘要

The present invention provides for a method for estimating or simulating one or more parameters of a stratum structure, comprising the steps of: determining a first model of the stratum structure; determining one or more variograms of one or more parameters in one or more of the strata; measuring the value of a parameter in a number of points; estimating on the basis of a variogram a probability density function (PDF) of the parameter at locations in the strata close to or at some distance from the locations where the parameter has been measured; and determining by using seismic data an acceptable value of the parameter at the location where the probability density function of the parameter has been determined using a variogram.
