METHOD OF PREDICTING MECHANICAL PROPERTIES OF ROCKS USING MINERAL COMPOSITIONS PROVIDED BY IN-SITU LOGGING TOOLS

摘要

A method for predicting mechanical properties of a transverse isotropic region of a rock formation traversed by a well bore including running a logging tool in the well bore; the mass percentages of minerals present in the rock formation surrounding the well bore are measured with the logging tool. The density of the minerals present in the rock formation surrounding the well bore is determined. The porosity of the rock formation surrounding the well bore is measured. From the porosity and the measured mass percentages and density of the minerals, all the transverse isotropic elastic coefficients of the rock formation are determined in real time.
