Towards In-situ Reservoir Nano-Agents

摘要

To test the future reality of having molecular agents in underground oil and gas reservoirs, an experimental research study was initiated to establish transport boundary conditions for nanoparticles in natural porous media; in this case, carbonate reservoir samples from the prolific ARAB-D formation. The study used scaled laboratory core flow tests with inert nanoparticle suspensions as a precursor for the injection of traceable nanoparticles into the reservoir. Overall, the experimental study was designed to generate baseline data for the injection response of nanoparticles in a bi-modal carbonate. It worked to correlate the impact on the rock permeability and the particle transport efficiency in terms of particle size, concentration, and surface chemistry. This paper details visions, procedures, and results from these tests.
