AI Technical Summary

Technical Problem

Current methods for analyzing drill solids in drilling fluids lack efficient techniques for determining mineralogy, particularly in real-time, which hampers accurate depth matching of cuttings and affects drilling efficiency and formation evaluation.

Method used

The use of nuclear magnetic resonance (NMR) spectrometry to measure magnetic susceptibility of drill fines, allowing for the identification of minerals and depth matching of cuttings by correlating magnetic susceptibility measurements with mineralogy logs, enabling continuous and accurate mineralogical analysis of drill solids.

Benefits of technology

Enables real-time mineralogical analysis of drill solids, facilitating accurate depth matching of cuttings and improving drilling efficiency by providing continuous, bulk measurements of fines, thereby enhancing formation evaluation and operational decision-making.

Abstract

A method for measuring at least one property of a sample includes obtaining a fluid sample including at least fines from a downhole environment, exposing the sample to a magnetic field, measuring a magnetic susceptibility of the fines in the sample in response to the magnetic field, and identifying at least one mineral present in the fines based at least partially on the magnetic susceptibility.
