“…Our results showed that with proper formulation, SLS is a promising EOR surfactant candidate with an ultralow IFT value suitable for EOR application. It is also noteworthy that the use of PFAD as demonstrated here is expected to lower the surfactant cost compared to the use of formulas as for example in [10,11,14].…”

“…In addition, they also reported that modification of alkali lignin to lignin sulphobetaine zwitterionic surfactants (LSBA) also exhibited a promising result for oil recovery [13]. Kakoty and Gogoi [14] have reported that the mixture of natural surfactant of SLS, sodium dodecyl sulfate (SDS) and a small amount of Na2CO3 can obtain ultralow IFT, in the range of 10 -1 -10 -2 mN/m.…”

Indonesia aims to implement large-scale enhanced oil recovery (EOR) to increase the national oil production. Chemical EOR is a promising technology to boost the production of old reservoirs with the aid of surfactants and polymers. Thus, the production of low-cost EOR surfactants from local resources with acceptable performance is highly attractive. The objective of the present work was to demonstrate the development of low-cost lignosulfonate surfactant production from kraft black liquor (BL). First, lignin was isolated from black liquor using a novel CO2 bubbling technique, followed by addition of coagulants. Next, sodium lignosulfonate (SLS) was synthesized from the resulting lignin, followed by formulation of SLS with octanol and palm fatty acid distillate (PFAD) soap to obtain an ultralow interfacial tension (IFT) surfactant. The initial IFT value of the SLS solution was already high at 0.7 mN/m. After formulation, the composition SLS:PFAD soap:octanol = 70:22:8 (wt%) improved the IFT value to 3.1 10-3 mN/m. An ultralow IFT in the range of 10-3 mN/m as achieved here fulfills the required IFT value for EOR surfactant.

“…Although anionic surfactants are most widely studied for EOR applications by many authors (Kakoty and Gogoi 2018;Barman et al 2018;Hazarika et al 2018;Das and Gogoi 2015), but certain characteristic properties of NIS make it more efficient for instance, its ultra-low IFT, non-volatility and environment friendly surfactant. They have effective solubilization towards water-insoluble or moderately soluble organic compounds and have the capability to alter surface characteristics and are stable at high salinity and temperature (Lawson 1978).…”

The paper focuses on the behaviour of nonionic surfactants (NISs) for enhanced oil recovery (EOR) processes with special reference to its applicability in the reservoirs of Upper Assam. The present work specifically studies three NISs, viz. Tergitol 15-s-7(Tg7), Tergitol 15-s-9 (Tg9) and Triton X 405(TX), based on their surface tension (ST), dynamic interfacial tension, hydrophilic-lipophilic balance, emulsion stability, aqueous stability, particle size analysis and phase behaviour. Simultaneously, crude oil from an oil field of upper Assam Basin was characterized based on API gravity, kinematic and dynamic viscosities, pour point and acid number. Core flood studies were conducted in the reservoir core to determine the recovery of crude oil during secondary water flood and EOR by NISs. It was observed that Tergitol 15-S-7 when mixed with Triton X-405 (Tg7TX) had the least interfacial tension (IFT) as compared to individual NIS and their mixtures. The recovery was found to be as high as 25.67% after secondary water flood from the original oil in place when Tg7TX followed by chase water was used as an exotic fluid for EOR. This work is an attempt to identify NISs mixtures for EOR for Upper Assam Basin.

Coenzyme Q10 is a compound that functions as an antioxidant with a large molecular weight of 863.36 g/mol and has lipophilic properties. This makes coenzyme Q10 need to be formulated to improve the solubility of the material and the delivery system in the skin. This study aims to determine the effect of surfactant variations (a combination of PEG-40 HCO and Span 80) on the physical characteristics of nanoemulsion and nanoemulsion gel preparations. Coenzyme Q10 is formulated using the rice bran oil oil phase with the combination surfactant. This research was made in 3 nanoemulsion formulas FI, F2, F3 and 3 nanoemulsion gel formulas F4, F5, F6. Evaluation of physical characteristics is done after 24 hours after the preparation is complete, observations made include organoleptic (shape, color and phase formed), pH, viscosity, droplet size, zeta potential and polydispersity index. The research data were processed statistically using the Kruskal-Wallis analysis and Mann-Whitney follow-up tests. The results showed that the surfactant concentration affected physical characteristics (viscosity, droplet size, zeta potential and polydispersity index) with a significantly different result (p <0.05) but the surfactant concentration did not affect the pH with the results not significantly different (p> 0.05)
