Abstract

Sand production persists in unconsolidated and weakly cemented formations of the South Caspian Basin. Mechanical sand control alone often fails to preserve wellbore stability and permeability balance. This study evaluates smart nanomaterial-based barriers designed to respond to changes in downhole stress and fluid chemistry. The system uses silica- and polymer-modified nanoparticles with reversible agglomeration and self-adjusting pore-bridging behavior under dynamic reservoir conditions. Laboratory tests used formation sand from Azerbaijani offshore wells, where nanocomposite formulations simulated in-situ consolidation. The nanocomposite increased compressive strength by 45–60% and reduced sand production rate by up to 80% versus conventional resin-based treatments. Permeability regulation tests showed up to 70% retention of the original formation permeability, supporting sustained flow without excessive plugging. Rheology and zeta potential results indicate physicochemical adaptation. Particle interactions intensify under higher ionic strength, driving selective deposition in weak zones, while the dispersion remains more mobile under normal flow. This behavior supports longer-term sand stabilization and a self-healing response to mechanical disturbances. These results support smart nanomaterial barriers as a practical route to adaptive sand mitigation with controlled permeability impact in mature South Caspian oil fields. Future work will scale the approach to pilot field trials and refine formulations for varying lithology and brine composition.
