Dynamic correlations between susceptibility gradients and T2-relaxation as a probe for wettability properties of liquid saturated rock cores

Abstract

We explore the use of correlations between susceptibility gradients, G₀, and T₂-relaxation (G₀-T₂), and show how the difference in response for oil and water with respect to G0 can be used for improved characterization of wettability of the internal surface in porous rock cores.
