A METHOD OF ESTIMATING A VOLUME FRACTION OF COAL IN A LAYERED GEOLOGICAL STRUCTURE

摘要

A method of estimating volume fraction of coal (h) in a layered geological structure having alternating layers of host material and coal. The method includes the steps of (a) sourcing surface seismic data pertaining to the layered geological structure; (b) determining at least one of the Thomsen parameters ε, δ and γ from the surface seismic data; and, (c) utilising one or a combination of two or more of the Thomsen parameters ε, δ and γ as an estimate of the volume fraction (h) of coal in the layered geological structure.
