ESTIMATING EFFECTIVE PERMEABILITIES.

摘要

A method for determining effective permeabilities of earth formations. The method includes receiving a database having one or more measurements made on a collection of fluid filled rocks and dividing the measurements into input measurements and output measurements. The input measurements include one or more measured properties of the fluid filled rocks and the output measurements include the corresponding effective permeabilities of the fluid filled rocks. The method then includes constructing a mapping function using the input measurements and the output measurements. The mapping function may then be used to predict the effective permeabilities of one or more rocks that are not part of the collection of fluid filled rocks. As such, the method may then include receiving one or more input measurements made on one or more rocks that are not part of the collection of fluid filled rocks and predicting the effective permeabilities of the rocks using the mapping function and the input measu rements made on the rocks.
