Paper presented at the SPE Conference at Oman Petroleum & Energy Show, March 21–23, 2022
Paper Number: SPE-200027-MS
... manipulation is the main driving mechanism behind wettability alteration observed in controlled ionic composition waterflooding (CICW) processes. Therefore, investigation of electrokinetic interactions at both brine/calcite and brine/crude-oil interfaces is important to optimize the injection water...

... and mechanism of interactions involving surfactant molecules at the solid/liquid interface and their efficiency as surface-active agents. Findings from this study will be used to improve understanding on how the role of various extensions on carboxylate surfactants affect surfactant adsorption. This will help...

Paper Number: SPE-200056-MS
... at the oil-water interface under reservoir conditions to 0.005 mN/m was studied in the laboratory. Geological and production data show that the main problem of the pilot areas is early encroachment of production wells by injected water because of its breakthrough and subsequent unwanted flow through...

... data. A new APG-based formulation was designed with an ultra-low IFT resulting in a much more compact amphiphilic structure along the oil-water interface. This study shows a great potential of APG surfactants and the relevant derivative formulations in improving oil production application for high...

... interactions occurring at the fluid/fluid and fluid/rock interfaces. Most of the laboratory studies reported so far have been focused on characterization of crude oil/brine/carbonate system and wettability alteration at micro- and macroscale using classic measurements, including contact angle, IFT, NMR, zeta...

... to the combined effect of 2 wt. % negatively-charged silica NPs and only 0.1 wt. % anionic surfactant. These results suggest that the repulsive interaction between negatively-charged NPs and anionic surfactant may result in pushing the surfactant molecules back towards the oil-water interface to enhance IFT...
