Furthermore, we investigated the effect of the additive on the capillary pressure properties and remaining water saturations on sandstone and carbonate rocks. To maximize the generality of the results we...

... of porosities. Because of that, the petrophysical properties of different facies are different and this was governed by the different depositional and diagenetic controls on each microfacies. These differences affect the rock fluid interaction in terms of contact angle and adhesion forces between surface...

.... Samples from Woodford and Caney outcrops in the Unites States of America were obtained. The mineralogy of the cores was measured using the FTIR technique. While the Woodford samples turned out to be Dolomite rich, the Caney samples were Quartz and clay rich. Spontaneous imbibition and contact angle...

... of three different oils with CO 2 . Last step consists of contact angle(CA) measurements of oil with dolomite rock in the presence of CO 2 and BSS. Brines are multicomponent with salinities ranging from 8,500 to 67,000 ppm. Comparison of surfactants was among solutions of an alcohol-propoxysulfate...

... compared to the short chain (heptanoic acid) as confirmed by the measured contact angles. Twice dilution of Arabian Gulf seawater has been found to be a less effecient EOR fluid for wettability alteration as compared to undiluted Arabian Gulf seawater. This was confirmed by the changes in the measured...

... Abstract Viscoelastic surfactants (VES) are used as diverting agents in carbonate matrix acidizing. However, these surfactants can adversely affect wettability around the wellbore. Receding contact angles were measured to study the effect of spent acid solutions with an amphoteric amine-oxide...

Regarding the brine effect, in acidic-lower salinity (NaCl brine) where oil adhesion occurs readily, hysteresis between advancing- receding contact angles is larger than for a neutral pH with high salinity brine. The consequence of these observations in flat surfaces is validated by flowing oil...
