Effluent concentrations of magnesium (Mg) and calcium (Ca) provided additional validation of the model's geochemical accuracy...

... recoveries are not completely clear and are even more puzzling when considering that these results are achieved with relatively low polymer viscosity - in most cases only 25-50 cP which still corresponds to unfavorable Mobility Ratios. One potential explanation put forward by some authors involves some...

..., and viscosities exhibit more excellent responsiveness in altering wettability. Overall, this study significantly advances smart water flooding in carbonate reservoirs, offering a framework for optimizing EOR techniques by salinity and ionic composition. Additionally, it establishes a screening criterion...

... Abstract At the Milne Point polymer flood (North Slope of Alaska), polymer retention is dominated by the clay, illite. Illite (and kaolinite) cause no delay in polymer propagation in Milne Point core material, but they reduce the effective polymer concentration and viscosity by a significant...

... Abstract The present work clarifies the mechanisms associated with bitumen viscosity reduction during ultrasound sonication. A Canadian (CDN) and Nigerian (NGR) bitumen, selected for this study, have a respective viscosity of 2,617 and 12,043 cP at room temperature. Two series of ultrasound...
