Abstract While the “low salinity waterflooding” (LSWF) has been praised for enhancing oil recovery from different core rocks, performance of technique in wettability environments remains unclear. The consensus is that LSWF does not work well water-wet carbonate reservoirs. main research objective was to determine effect on displacement efficiency (DE) environments. Carbonate flooding experiment...

On the basis of generalization experience in development multilayer high-viscosity fields X influence waterflooding late stage on oil recovery factor productive formations has been studied. By applying statistical methods data processing dependence reservoir flushing factor, with a sufficiently high correlation coefficient, obtained. The obtained confirms theoretical from developed and can be u...

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...

Imbibition is an important mechanism of recovery during waterflooding and low flow-back fracking in shale reservoirs. Experiments were carried out to study the development imbibition samples. The effects clay minerals, especially illite IS, mainly investigated discussed. under different pressures was conducted compared. influence minerals on significant complex. It shown that content IS small c...
