New Insights into Microscopic Fluid/Rock Interaction: MR-CT Microscopy Approach

摘要

In the current work, we propose a new suit of core analysis tools, called MR-CT Microscopy. Nuclear magnetic resonance combined with X-ray computed tomography improves the description of pore property changes as the result of core flooding with various types of fluids. With its ability to offer spatial fluid-rock interaction information with proper mineralogy quantification, MR-CT Microscopy offers a new opportunity to observe microscopic events within reservoir porous media without damaging the sample. To demonstrate the benefit of the proposed analytical tool, core flooding test were performed to investigate chemical stimulation treatment for a set of Upper Jurassic carbonate core plugs from Saudi Arabia.
