The effect of methylene blue and organic acids on the wettability of sandstone formation: Implications for enhanced oil recovery

Capillarity, Год журнала: 2023, Номер 10(2), С. 29 - 37

Fossil fuels are the primary global energy source, and their improved production will ensure a balance between increasing demand supply. Chemical-enhanced oil recovery has been well thought of as promising method for hydrocarbon production. However, effectiveness this depends on wettability rock-oil-brine systems' Previous studies have shown that oil-wet rock demonstrated water-wet state when treated with surface active chemicals like surfactants, nanofluids. Moreover, attention become focused application hazardous pollutants such methyl orange methylene blue to enhance CO2/H2 containment security host by altering its wettability. Nevertheless, capacity modify trapped hydrocarbons in sandstone reservoirs is yet be explored. Thus, present study, used modifier from quartz rocks aged stearic acid solution (10-2 mol/L). First, organic-aged various concentrations (10-100 mg/L) one week at 60 °C. Then, contact angle measurements performed different temperatures (25 50 °C) under pressures (10-20 MPa) brine salinities (0-0.3 M). found turn hydrophobic organic acid/n-decane 20 MPa blue, hydrophobicity decrease, thus suggesting promoted treatment. Overall, results demonstrate most favourable condition reducing via treatment 100 mg/L blue. Hence, injection into deep underground potential produce more residual hydrocarbons.

Significant amounts of hydrocarbon resources are left behind after primary and secondary recovery processes, necessitating the application enhanced oil (EOR) techniques for improving trapped from subsurface formations. In this respect, wettability rock is crucial in assessing sweep efficiency oil. The reservoirs inherently contaminated with organic acids, which renders them hydrophobic. Recent research has revealed significant impacts nanofluids, surfactants, methyl orange on altering organic-acid-contaminated formations into water-wet state. This suggests that toxic dye methylene blue (MB), presently disposed huge quantities contaminates waters, could be used EOR. However, mechanisms using MB solution attaining hydrophilic conditions not fully understood. Therefore, present work examines reversal Khewra sandstone samples (obtained outcrop Potwar Basin, Pakistan) under downhole temperature pressure conditions. prepared by aging 10-2 mol/L stearic acid subsequently treated various aqueous (10-100 mg/L) 1 week. Contact angle measurements then conducted physio-thermal (0.1-20 MPa, 25-50 °C, salinities 0.1-0.3 M). results indicate become hydrophobic presence increased pressure, temperature, salinity. changes oil-wet to preferentially solutions, thus highlighting favorable effects EOR formation. Moreover, most change observed sample was aged 100 mg/L MB. These suggest injecting deep underground may produce more residual hydrocarbons.

The efficient development of oil resources is significant for alleviating the increasingly serious contradiction between supply and demand ensuring national security. Surfactant flooding technology one essential methods to enhance recovery has been widely used in gas development. screening traditional surfactants displacement are mainly focused on reducing interfacial tension based theory capillary number while ignoring emulsification effect surfactants. For different types residual oil/remaining oil, main contradictions faced by target reservoir should be thoroughly analyzed clarify whether performance reduce or strong capacity, then screen suitable characteristics crude properties. In this article, principle application surfactant reviewed from two aspects performance, interrelationship capacity explored, evaluation indicators existing problems detail. Most past were water extraction rate. A method evaluating ability introduced. It expected provide scientific guidance displacement.

Effect of Titanium Dioxide Nanoparticles on Surfactants and Their Impact on the Interfacial Properties of the Oil–Water–Rock System

ACS Omega, Год журнала: 2023, Номер 8(41), С. 38539 - 38545

Опубликована: Окт. 5, 2023

The application of nanoparticles (NPs) in the oil and gas industry has received wide attention recent years because it is increasingly being considered a promising approach to recovering trapped conventional hydrocarbon reservoirs. Numerous studies have demonstrated that combining with surfactant can enhance performance by changing interfacial properties solution when comes contact crude rock surfaces. However, more information additional experimental data are required concerning titanium dioxide alkyl ethoxy carboxylic surfactants. In this study, we measure changes tension wettability due addition (0, 100, 250, 500 ppm) using spinning drop tensiometer angle measurements. oil–water (surfactant) system decreases approximately two orders magnitude an increasing concentration, exhibiting minimum value 5.85 × 10–5 mN/m. Similarly, on surface Berea sandstone dioxide, reaching 8.8°. These results demonstrate potential new maximize recovery significantly improve production.
