George E. P. Box wrote, "All models are false, but some models are useful." In that spirit, we examine fractionalflow models for foam enhanced oil recovery (EOR). This approach has long fascinated practitioners by transforming a physics problem first into a mathematics problem and then into a geometry puzzle. This approach, sometimes called the method of characteristics (MOC), makes many seriou...

Abstract Chemical enhanced oil recovery (EOR) methods are shown to sweep the residual by altering physical properties of fluids after waterflooding improve recovery. This work presents an experimental study on surfactant/polymer injection for EOR in sandstone reservoirs. Interfacial tension measurements, emulsification and rheology tests performed select best candidates from thirteen commercial...

Foam-enhanced oil recovery (EOR) is poised to become one of the most promising tertiary techniques keep up with continuously increasing global energy demands. Due their low sensitivity gravity and permeability heterogeneities that improve sweep efficiency, foams are preferred injection fluids over water or gas. Although foam has been used in field control gas mobility, its success still hindere...

Dimethyl ether (DME) is a compound first introduced by Shell as chemical solvent for enhanced oil recovery (EOR). This study aims to investigate the efficiency of EOR using minimum miscible pressure (MMP) and viscous gravity number when mixed CO2 DME injected. Adding water-alternating-gas process reduces MMP number. Reduction in results conditions at lower pressures, which has favorable effect ...

since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

Carbon Capture and Storage (CCS) or Utilization (CCU) are expected to be powerful tools to reduce CO2 emissions to the atmosphere from large scale sources, such as electric power, oil refinery, steal making, cement plants, with continuing their activities Those contain the CO2 separation or capture from flue gases at the plants and the transport and injecting CO2 into oil and gas reservoirs, an...

To increase the oil recovery factor (RF), enhanced (EOR) methods are applied: chemical, gas, thermal, and combined ones. Standard laboratory research for selecting optimizing EOR technologies require a lot of time resources, as well core material, which is often in short supply. optimize selection reagents field development technologies, use microfluidic technology proposed i.e. conducting expe...

As the important role of enhanced oil recovery (EOR) in meeting world’s energy requirement is growing, use nanoparticles lieu of, or combination with, existing EOR agents to expand EOR’s applicable range receiving significant attention. Two most actively investigated applications are: 1) wettability alteration by addition into waterflood injection water, and 2) nanoparticle-stabilized Pickering...
