Enhancing sand control in loose reservoirs: nanofluid application

This paper introduces a novel epoxy-based nanofluid for sand control in loose reservoirs prone to sand production issues. The nanofluid combines epoxy resin with carbon nitride nanoparticles and a gas generating agent to enhance both compressive strength and permeability. Experimental studies demonstrate significant improvements in compressive strength and permeability, indicating the potential effectiveness of the nanofluid in consolidating sand in oil and gas reservoirs. Sandpack flooding experiments under reservoir conditions reveal promising results, suggesting the nanofluid's suitability for various permeability characteristics. These findings propose the epoxy/g-C₃N₄ nanofluid as a promising solution for sand consolidation, warranting further research and field testing for practical application in reservoir engineering. Keywords: sand control; epoxy nanofluid; chemical sand consolidation; graphitic carbon nitride; compressive strength enhancement; permeability control.
