The growing need for energy and the depletion of oil wells necessitate advanced Enhanced Oil Recovery (EOR) techniques, particularly water polymer flooding, which play a crucial role in augmenting hydrocarbon recovery rates. However, flooding high-permeability layers often leads to breakthroughs, reduced sweep efficiency, formation preferential channels, posing significant challenges reservoir management. Conformance control treatments, including use microspheres, offer promising solution by sealing zones enhancing efficiency. This study focuses on application fluorescent microspheres based polyacrylamide, is extensively employed sector as an displacement agent. Fluorescent polymers called Poly 400, 200, 600, incorporating cationic methacrylamide monomers, were synthesized through copolymerization create amphiphilic with enhanced stability functionality. These evaluated tests using quarter-five-spot model transparent quartz glass under UV light, allowing instantaneous measurement observation fluorescence intensity. At conditions, experiments confirm that incremental after 13.1%, 9.1%, 6.1% OOIP respectively. findings showed could efficiently target layers, adapt varying pore throat sizes, improve plugging rate thereby optimizing recovery. A subsequent simulation CMG simulator provided further insights into efficacy these EOR agents, revealing their potential enhance efficiency Simulation results saturation decreased from 68% (initial) 13.5%, 16.1%, 18.3% 600 work highlights valuable tool applications, offering advancements management optimization.

Steady Shear Rheology and Surface Activity of Polymer-Surfactant Mixtures

Polymers, Journal Year: 2025, Volume and Issue: 17(3), P. 364 - 364

Published: Jan. 29, 2025

Understanding the interactions between polymers and surfactants is critical for designing advanced fluid systems used in applications such as enhanced oil recovery, drilling, chemical processing. This study examines effects of five surfactants: two anionic (Stepanol WA-100 Stepwet DF-95), one cationic (HTAB), zwitterionic (Amphosol CG), non-ionic (Alfonic 1412-3 Ethoxylate), on steady shear rheology surface activity polymers, namely hydroxyethyl cellulose based polymer (LR-400) polyacrylamide (Praestol 2540TR). The polymer-surfactant solutions behave shear-thinning fluids follow power-law model. Anionic exhibit a strong effect LR-400 solution. consistency index rises sharply with increase surfactant concentration. Also, become highly other solution are small to modest. None investigated influence Praestol 2540TR. Only weak modest observed polymers. tension decreases Zwitterionic Amphosol CG found be most effective reducing at given concentration ppm. also raises electrical conductivity largest extent. From changes slope versus plots, approximate values aggregation (CAC) saturation point (PSP) estimated.
