Emulsification and pH Control for Sustainable Thermochemical Fluids Reactivity.

Managing chemical reactivity is crucial for sustainable chemistry and industry, fostering efficiency, reducing chemical waste, saving energy, and protecting the environment. Emulsification is used for different purposes, among them controlling the reactivity of highly reactive chemicals. Thermochemical fluids (TCFs), such as NHCl and NaNO salts, have been utilized in various applications, including the oil and gas industry.

Static and dynamic adsorption of a gemini surfactant on a carbonate rock in the presence of low salinity water.

In chemical enhanced oil recovery (cEOR) techniques, surfactants are extensively used for enhancing oil recovery by reducing interfacial tension and/or modifying wettability. However, the effectiveness and economic feasibility of the cEOR process are compromised due to the adsorption of surfactants on rock surfaces. Therefore, surfactant adsorption must be reduced to make the cEOR process efficient and economical.

Surfactant Adsorption Isotherms: A Review.

The need to minimize surfactant adsorption on rock surfaces has been a challenge for surfactant-based, chemical-enhanced oil recovery (cEOR) techniques. Modeling of adsorption experimental data is very useful in estimating the extent of adsorption and, hence, optimizing the process. This paper presents a mini-review of surfactant adsorption isotherms, focusing on theories of adsorption and the most frequently used adsorption isotherm models.

Mass and Heat Transfer of Thermochemical Fluids in a Fractured Porous Medium.

The desire to improve hydraulic fracture complexity has encouraged the use of thermochemical additives with fracturing fluids. These chemicals generate tremendous heat and pressure pulses upon reaction. This study developed a model of thermochemical fluids' advection-reactive transport in hydraulic fractures to better understand thermochemical fluids' penetration length and heat propagation distance along the fracture and into the surrounding porous media.

Wettability of rock/CO/brine and rock/oil/CO-enriched-brine systems:Critical parametric analysis and future outlook.

CO geo-sequestration is a promising technology to permanently store CO in geological formations to control the atmospheric carbon footprint. In addition, CO is frequently utilized in enhanced oil recovery operations to accelerate oil production. Both, CO geo-storage and EOR, are significantly influenced by the wettability of the associated rock/CO/brine systems.
