recovery factor is an important parameter in determining commercial viability of the oil reservoirs. wettability is a major factor that affects oil recovery. therefore, changing rock wettability may enhance oil recovery. in this paper, the effect of polysilicon nanoparticles on wettability change of iranian carbonate reservoir is investigated. to assess this, hydrophilic changes of carbonate ro...

Enzymes have recently been considered as possible agents for enhanced oil recovery (EOR) acting at the liquid–solid interface. One way to assess this is via measuring the wettability of calcite surfaces, important for EOR methods in carbonaceous reservoirs. In the present work, we have experimentally investigated the effect of enzymes on the wettability of calcite mineral surfaces with oil–brin...

During this study, a comprehensive investigation of low salinity water alternating CO2 injection was performed for enhanced oil recovery in oil-wet carbonate reservoirs. A synergy interfacial mechanisms such as IFT, wettability alteration, solubility, swelling, shielding effect, and rock dissolution considered two three-phase systems. Results showed that the monovalent ions, NaCl or KCl, inhibi...

Injection of carbon dioxide in deep saline aquifers is considered as a method of carbon sequestration. The efficiency of this process is dependent on the fluid-fluid and rock-fluid interactions inside the porous media. For instance, the final storage capacity and total amount of capillary-trapped CO2 inside an aquifer are affected by the interfacial tension between the fluids and the contact an...

for Project NMR well logging provides a record of formation porosity, permeability, irreducible water saturation, oil saturation and viscosity. In the absence of formation material, the NMR logs are interpreted using default assumptions. Special core analysis on core samples of formation material provides a calibration between the log response and the desired rock and/or fluid property. The pro...

our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (nano-cs), for the first time. the second objective was to compare and contrast such penetrations to those of chitosan (cs) itself, as well as sodium hypochlorite (naocl), chlorhexidine (chx) and ethylenediamintetraacetic acid (edta), at the routinely used concentrations. molar roots were split l...

the influence of maleic anhydride-polypropylene (mapp) (0, 2, 3 and 5%) as a compatibilizer on the wettability of polypropylene/wood flour/glass fiber hybrid composites was studied by using the contact angle determination technique. sample slats with a cross section of 10×70 mm were made by a twin screw extruder. specimens were conditioned at room temperature and the angles between the water dr...
