“…On the other hand, thermal and gas injection methods are other types of EOR techniques that can be more cost-effective, although their suitability can vary depending on reservoir conditions [ 84 , 85 , 86 ]. Thermal recovery methods typically involve the use of heat, often in the form of steam generated by burning natural gas, to reduce oil viscosity and improve its flow.…”

Enhanced oil recovery (EOR) processes are technologies used in the oil and gas industry to maximize the extraction of residual oil from reservoirs after primary and secondary recovery methods have been carried out. The injection into the reservoir of surface-active substances capable of reducing the surface tension between oil and the rock surface should favor its extraction with significant economic repercussions. However, the most commonly used surfactants in EOR are derived from petroleum, and their use can have negative environmental impacts, such as toxicity and persistence in the environment. Biosurfactants on the other hand, are derived from renewable resources and are biodegradable, making them potentially more sustainable and environmentally friendly. The present review intends to offer an updated overview of the most significant results available in scientific literature on the potential application of biosurfactants in the context of EOR processes. Aspects such as production strategies, techniques for characterizing the mechanisms of action and the pros and cons of the application of biosurfactants as a principal method for EOR will be illustrated and discussed in detail. Optimized concepts such as the HLD in biosurfactant choice and design for EOR are also discussed. The scientific findings that are illustrated and reviewed in this paper show why general emphasis needs to be placed on the development and adoption of biosurfactants in EOR as a substantial contribution to a more sustainable and environmentally friendly oil and gas industry.

“…11,12 Pore geometry and wettability are the main effective parameters in these two mechanisms. 13 The trapped condensate phenomenon, which is also called condensate blockage, leads to a dramatic reduction of the permeability and, so, significantly decreases the recovery of hydrocarbons and productivity of the well. 14 For example, Afidick et al 15 showed that, when the maximum amount of condensate was around 1%, the productivity of the well was decreased by 50%.…”

The gas condensate reservoir is classified as a natural gas resource that produces condensate liquid in the reservoir when the pressure in the reservoir drops below the dew point. An innovative strategy to address condensate blockage near the wellbore involves modifying the wettability of the surface of the reservoir rock. This is achieved through chemical treatment, transitioning the surface from a state of strong liquid-wetting to either strong or intermediate gas-wetting. This modern approach effectively mitigates condensate blockage and its associated challenges. Adjusting and sustaining wettability conditions within gas reservoirs requires proper chemicals for a certain reservoir condition. The paper presents a thorough review of wettability and the processes involved in wettability alteration specifically in gas condensate reservoirs. Then, the commonly used wettability alteration chemicals along with their induced flow mechanisms are discussed and reviewed together with a molecular modeling point of view on modern problems of wetting and interfacial phenomena. This paper also focuses on using nanoparticles and fluorochemicals as wettability alteration agents, given that fluorinated nanoparticles are allegedly superior to the chemical wettability altering agents as they change the wettability of the rock surface by modifying both surface energy and surface roughness. This Review indicates the promising use of various nanoparticles along with fluoro materials to enhance ultimate hydrocarbon recovery in gas condensate reservoirs. In the next part, molecular dynamic simulation of imbibition of n-alkanes in kerogen organic slits are presented. The influence of competitive adsorption on multicomponent flows of crude oil and wetting transition on surfaces with molecular roughness are discussed. Actual problems and challenges of molecular modeling methods are also presented.
