Abstract
<jats:title>Abstract</jats:title> <jats:p>Polymer injection has emerged as one of the most effective Enhanced Oil Recovery (EOR) techniques for mature reservoirs, offering significant improvements in sweep efficiency and ultimate recovery. By increasing the viscosity of injected water, polymer flooding reduces the mobility ratio between displacing and displaced fluids, thereby mitigating viscous fingering and improving conformance. Despite these technical advantages, conventional polymer injection facilities often face challenges related to high capital costs, extended lead times, and complex logistics—particularly in remote or infrastructure-limited environments. These constraints have historically limited the scalability and economic viability of polymer EOR projects (Lake et al. 2014).</jats:p> <jats:p>This paper introduces a modular and containerized approach to polymer preparation and injection, designed to overcome these limitations. The proposed system integrates advanced hydration, mixing, and injection technologies within a compact, transportable architecture. Key innovations include the use of low shear pressure control valves—Linear Pressure Reducers (LPR) and Conical Pressure Reducers (CPR)—which replace conventional chokes to preserve polymer integrity during multi-well injection from a single pump. Additionally, the incorporation of a Polymer Slicing Unit (PSU) enables the preparation of highly concentrated mother solutions, reducing footprint and simplifying logistics.</jats:p> <jats:p>The methodology combines engineering design principles with economic modeling and environmental impact assessments. Field deployments in Argentina, Oman, and Suriname validate the adaptability of modular systems across diverse operational contexts. Results demonstrate accelerated project timelines, reduced capital and operating expenditures, and improved safety and environmental compliance. Comparative analysis against conventional systems highlights the advantages of modularity in terms of scalability, operational flexibility, and sustainability.</jats:p> <jats:p>This paper concludes that modular polymer injection systems represent a transformative solution for modern EOR projects, aligning technical performance with economic and environmental objectives. The findings provide a roadmap for operators seeking to implement short-cycle development strategies and enhance equipment utilization in challenging environments.</jats:p>
