..., et al. The paper has not been peer reviewed. _ The study detailed in the complete paper aims at understanding the effect of a surfactant that the authors refer to as a high-temperature emulsifying agent (HEA) as an additive in the steam-assisted gravity drainage (SAGD) process. The work provides...

... the water surface tension. Another set of surface-tension tests was conducted to evaluate the effect of the addition of three different types of surfactants (Surfactants A, B, and C) on reducing the surface tension of the enzyme system. The results showed that the enzyme breaker has fairly low surface...

... Unconventional Resources Technology Conference (URTeC) reported on field tests of surfactants and natural gas injection on Permian Basin wells which delivered sufficiently encouraging results to justify an expanded testing program. (URTeC 3870505 and URTeC 3871386). Chevron described a systematic effort by its...

... on the theme of efficiency, the second paper pivots to the realm of surfactants, exploring their role in wettability alteration within unconventional liquid-rich reservoirs. This research provides a systematic approach for screening thermally stable surfactants under reservoir conditions, crucial for improving...

... and improving gas lift. Foams from surfactant injection increase the viscosity of gas, thus reducing gas movement and velocity but with a pressure penalty. Surfactant concentration also decreases the liquid’s surface tension to a minimum value reached when micelles start to form, called the critical micelle...

... of chemicals added to water: polymers, surfactants, and alkalis. In simple terms, the polymers increase the viscosity of injected water, thus improving its mobility, similar to adding a small amount of corn starch to thicken soups. The surfactants reduce the interfacial tension (IFT) between the oil and water...
