“…The absorption band around 2,920, 2292, and 2236 cm −1 in the three spectrograms shown in Figure 10 depict the C-H symmetric vibration of the saturated hydrocarbons and O-H band due to stretching vibration at 3,435 cm −1 . C¼O stretching peaks appeared between 1,627 and 1,870 cm −1 , which confirms the presence of carbonyl components like acids and aliphatic esters in the sand particles (Saxena, Kumar, & Mandal, 2018).…”

The soil textures, soil settlements, soil water-holding capacity, and elevation angles are parameters for landslides in the Province of Iloilo. They are usually triggered during heavy rainstorms, causing severe property damage and sometimes causing casualties. This experimental study aims to determine how these parameters are factors for landslides and flood monitoring and uses three methods to provide ease and continuity of measurements. The Fourier transforms infrared (FTIR)spectroscopy analysis for soil textures, the Imhoff cone for the settling and water-holding capacity of the soil, and an improvised apparatus to test how the slopes affect the transportation of soil materials. FTIR Soil analysis reveals that contents of clay and organic matter directly affect soil water-holding capacity due to the larger surface area. The smaller particle sizes, such as clay, have a larger surface area leading to a higher water-holding ability. A landslide-prone zone has a lesser settling time except for the sand that settles fastest due to larger masses. An angle of 20 degrees has more mass movement too much higher slopes like 55 and 85 degrees. The increase in height or angle of the elevation decreases stability, leading to less mass movement. Less mass movement leads to the conclusion that there are rare landslides in the very high slope range due to fewer vibrations or soil movements caused by human activities and being compact or stable. This study is crucial for forecasting and preventing geohydrological processes and developing better landslide warning strategies to mitigate risks and reduce socioeconomic damage.

Surfactants adsorption onto carbonate reservoirs would cause surfactants concentrations decrease in surfactant flooding, which would decrease surfactant efficiency in practical applications of enhanced oil recovery (EOR) processes. Different surfactants could be classified as cationic surfactants, anionic surfactants, non-ionic surfactants according to the main charge, or be classified as chemical surfactant and bio-surfactant according to the surfactant origin. However, the research on different type surfactants adsorption on carbonate reservoirs surface differences was few. Therefore, five representative surfactants (CTAB, SDS, TX-100, sophorolipid, rhamonilipid) adsorption effect onto carbonate reservoirs surface was studied. Owing to the fact that the salinity and temperature in underground carbonate reservoirs were high during the EOR process, it is vital to study the salinity effect and temperature effect on surfactant adsorption. In this study, different surfactants species, temperature and salinity adsorption onto carbonate reservoirs were studied. The adsorption isotherms were fitted by Langmuir, Freundlich, Temkin and Linear models, and the first three models fitting effect were good. The results showed that cationic surfactants adsorption quantity was higher than anionic surfactants, and the non-ionic surfactants adsorption quantity was the lowest. When the temperature increased, the surfactants adsorption would decrease, because the adsorption process was exothermic process, and increasing temperature would inhibit the adsorption. The higher salinity would increase surfactants adsorption because higher salinity could compress electric double layer. In order to decrease surfactants adsorption, SiO2 nanoparticles and TiO2 nanoparticles were added to surfactants solutions, and then surfactants could adsorb onto nanoparticles surface, then the steric hindrance between surfactant molecules would increase, which could decrease surfactants adsorption. Contact angle results indicated that surfactants adsorption made the carbonate reservoir wettability alteration. In the end, surfactants (with or without SiO2 nanoparticles) adsorption onto carbonate reservoirs mechanism were studied by molecular dynamics simulation. The simulation results indicated that the surfactants molecules could adsorb onto SiO2 nanoparticles surface, and then the surfactants adsorption quantity onto carbonate rocks would decrease, which was in accordance with the experiments results.

“…Owing to the importance of surfactant adsorption-desorption properties, studies have been where the adsorption was researched under conditions that resemble those of Mexican reservoirs (Flores et al, 2011;Toledo-Piña et al, 2014). Studies under high salinity conditions, over limestone, over-carbonated surfaces, and sandstones are also available (Barati et al, 2016;Budhathoki et al, 2016;Chen et al, 2017;Han et al, 2013;Saxena et al, 2018;Wang et al, 2015). Massarweh and Abushaikha (2020) reviewed the use of surfactants in EOR in 2020, they found that the surfactants have successfully increased the oil recovery through interfacial tension reduction, wettability alteration, foam generation, and emulsification.…”

The adsorption of a supramolecular surfactant formed by the non‐covalent interactions among sodium (E)‐dodec‐2‐ene‐1‐sulfonate, sodium 3‐hydroxydodecane‐1‐sulfonate and 3‐[(3‐dodecanoylamidopropyl)dimethylazaniumyl]‐2‐hydroxypropane‐1‐sulfonate onto limestone under static and dynamic conditions in the presence of seawater and connate water is presented. In the static test at 70°C and atmospheric pressure, the adsorption capacity of the saturated monolayer was 8.65 mg/g for seawater and 4.05 mg/g for connate water. This behavior was associated with the increase of the critical micellar concentration from 217 ppm in seawater to 672 ppm in connate water, which is related to the capacity of the supramolecular surfactant to form complexes at high salinity and hardness. The dynamic experiment was carried out at 130°C with a pressure of 16,500 kPa, a flow rate of 90 mL/h and a dose of 2000 ppm of the surfactant. An adsorption of 0.230 mg/g was found in seawater, while a value of 0.109 mg/g was obtained in connate water, consistent with the static experiment. In addition, spontaneous imbibition experiments for connate and connate water with 2000 ppm of surfactant showed an increase in the oil recovery factor from 3% to 17% in the presence of surfactant at 100°C. It was observed that the rock changed from oil‐wettable to water‐wettable, indicating that the supramolecular complex retains its capability to form the monolayer on the rock surface. In contrast to the ionic and cationic conventional surfactants, the experimental evidence indicates that the surfactant preserves its properties under the extreme conditions found in mature Mexican carbonate reservoirs.
