Title: Applying magnetic anisotropy to pore space characterization

The anisotropic properties of a formation’s pore space largely control preferred flow directions. An accurate 3D description of pore space properties is thus essential in reservoir characterization and fluid migration studies. Traditional characterization methods face trade-offs between sample volume and resolution amongst other challenges. Magnetic pore fabrics, i.e., the anisotropy of magnetic susceptibility in ferrofluid-impregnated samples, have been proposed to capture pores down to 10 nm in standard-sized samples. Promising empirical relationships exist between magnetic pore fabrics and pore shape and orientation distributions, but are compromised by a large variability between studies. New numerical and experimental data provide insight into the sources of this variability, and allow for a quantitative interpretation of magnetic pore fabrics in future applications.
