Use of microemulsion in enhanced oil recovery has become more attractive in recent years because of its high level of extraction efficiency. Experimental investigations have been made on characterization of microemulsions of oil-brinesurfactant/cosurfactant system for its use in enhanced oil recovery (EOR). Sodium dodecyl sulfate, propan-1-ol and heptane were selected as surfactant, cosurfactan...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...

Thermal oil recovery is a special technique belonging to Enhanced Oil Recovery (EOR) methods and includes steam flooding, cyclic stimulation, in-situ combustion (fire flooding) applied especially in the heavy reservoirs. Starting 1970 (ISC) process has been successfully continuously Suplacu de Barcau field, currently this one representing most important reservoir operated by ISC world. field sh...

Abstract The suitable concentration of mobility-controlled oil displacement agent was selected through laboratory experiments, and the development mechanism in water flooding process studied. results show that when mobility control is 0.15 %, viscosity reduction effect best. Fluid injection pressure can be reduced by controlled agent. improve efficiency, recovery rate Tuha heavy increased from ...

Currently the waste generated from public consumption in Indonesia is very high. One such used palm oil households and food companies. Utilization of this research by recycling into surfactants which will be Enhanced Oil Recovery (EOR) process. The surfactant concentrations were 1.3%, 1.5%, 2%, 2.2% 2.5%. began with refining cooking banana peels for 24 hours. In order to make surfactants, mixed...
