Surfactants are favorable chemical additives that widely utilized in enhanced oil recovery (EOR) due to their inherent abilities such as wettability alteration and interfacial tension (IFT) reduction. However, most of the commercially available surfactants expensive, hazardous environment, can readily adsorb on surface porous rocks. The present work investigates possible application a novel plant-based natural surfactant derived from weed, Eichhornia crassipes, for EOR. IFT measurements have...
Abstract A significant amount of oil (i.e. 60–70%) remains trapped in reservoirs after the conventional primary and secondary methods recovery. Enhanced recovery (EOR) are therefore necessary to recover major fraction unrecovered from meet present-day energy demands. The chemical EOR method is one promising where various additives, such as alkalis, surfactants, polymer, combination all alkali–surfactant–polymer (ASP) or surfactant–polymer (SP) solutions, injected into reservoir improve...
Excessive water production is a significant challenge during hydrocarbon from oil and gas reservoirs, it typically controlled by polymer gel placement. However, the fundamental process in terms of how precisely this reduces reservoirs rarely reported. The objective paper to investigate impact cross-linked polyacrylamide (poly(acrylamide-co-acrylic acid) partial sodium salt) as relative permeability modifier for sandstone/gas/water system provides insights into detailed situ behavior inside...
Surfactants are considered as beneficial chemical additives in enhanced oil recovery due to their capability of reducing the interfacial tension and altering wettability. However, loss surfactant by adsorption on surface porous rock is one significant drawbacks flooding. The mechanism, equilibrium, kinetics a natural derived from weed, Eichhornia crassipes, sandstone sand surfaces have been investigated through batch experiments at different concentrations (i.e., 1000–5000 mg dm−3),...
The enhanced oil recovery (EOR) method is widely used for recovering residual crude after implementing conventional techniques. Chemical additives, such as surfactants, are considered beneficial EOR. Their efficacy assessed based on their ability to reduce interfacial tension, modify wettability, and establish a stable emulsion system. Understanding the mechanism of surfactant adsorption at oil–water interface critical effectively flooding. In this work, we have studied natural synthesized...
The present study highlights the possible utilization of polymer blend polyacrylamide and xanthan gum for an enhanced oil recovery application. A detailed investigation was carried out to examine effect alkali high-performance surfactants on solution's rheological properties emulsion stability characteristics. Besides, alteration in flow characteristics polymeric solutions corresponding reservoir conditions examined. application blends seems be promising based study, it shows higher...
Abstract Nanoparticle-based foam shows promise to enhance oil recovery; however, there is limited experimental investigation on the influence of injection sequence recovery. The objective present study systematically compare SiO2 nanoparticle-based foam, viz, brine-gas-foam-gas (N2) and brine-foam-brine, using core flooding simulation analyses. Relative permeability endpoints Corey exponents are found by history matching production data a commercial software. To match parameters assess...
