Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 12–15, 2018
Paper Number: SPE-193277-MS
... Abstract Surfactin is an anionic surfactant generated by bacteria. Although it has high ability to decrease interfacial tension (IFT) between oil and water, it binds with bivalent cations and forms precipitation. Because the precipitation causes the significant reduction of reservoir...

Paper Number: SPE-204611-MS
...Abstract Abstract The first surfactant-based pilots can be traced back to the 1960s and since then almost a hundred field tests have taken place. Interestingly, almost half of these pilots have used an alkali (ASP) and the other half has not (SP). This reflects the current status...

Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 9–12, 2020
Paper Number: SPE-202738-MS
... Abstract Surfactants and polymers are used in enhanced oil recovery (EOR) to reduce interfacial tension and increase the viscosity of displacing fluid, respectively. For oil-wet to mixed-wet systems, especially carbonates, which tend to be heavily fractured, wettability becomes a key parameter...

... Abstract A comprehensive chemical enhanced oil recovery (CEOR) laboratory evaluation program was carried out to compare surfactants for alkali-surfactant-polymer (ASP) and surfactant-polymer (SP) implementation in a giant Middle East sandstone oil reservoir. The efficacies of ASP and SP floods...

Paper presented at the SPE Western Regional Meeting, April 23–26, 2019
Paper Number: SPE-195254-MS
... To indirectly estimate the polarity of the crude oil, surfactant, and microemulsions, dielectric constant measurements were used using a FieldFox handheld RF Vector Network Analyzer at 200 MHz to 4 GHz. Since the true dielectric constant of an emulsion is at a high frequency, measurements were...

Paper presented at the SPE International Conference on Oilfield Chemistry, April 8–9, 2019
Paper Number: SPE-193595-MS
... Abstract Adsorption of surfactant onto rock surfaces is dependent upon a number of factors, including characteristics of both the adsorbent and surfactant molecules. Considering that surfactant-based unconventional means to improve oil recovery are strongly dependent on the interaction...
