“…ILs achieve changes in their physical and chemical properties through changes in cations, substituents, and anions. Compared with the liquid phase of traditional solvents (mostly between 75 • C and 200 • C), ILs have no vapor pressure and present a liquid phase from room temperature to 400 • C, which has a very wide range of operations and applications [89][90][91]. ILs are green solvents in terms of applicability, environmental protection, and economy.…”

In situ catalytic upgrading of heavy oil decomposes viscous heavy oil underground through a series of complex chemical and physical reactions with the aid of an injected catalyst, and permits the resulting lighter components to flow to the producer under a normal pressure drive. By eliminating or substantially reducing the use of steam, which is prevalently used in current heavy oil productions worldwide and is a potent source of contamination concerns if not treated properly, in situ catalytic upgrading is intrinsically environmental-friendly and widely regarded as one of the promising techniques routes to decarbonize the oil industry. The present review provides a state-of-the-art summarization of the technologies of in situ catalytic upgrading and viscosity reduction in heavy oil from the aspects of catalyst selections, catalytic mechanisms, catalytic methods, and applications. The various types of widely used catalysts are compared and discussed in detail. Factors that impact the efficacy of the in situ upgrading of heavy oil are presented. The challenges and recommendations for future development are also furnished. This in-depth review is intended to give a well-rounded introduction to critical aspects on which the in situ catalytic application can shed light in the development of the world’s extra heavy oil reservoirs.

“…These materials have been tested to reduce pressure drop in pipelines by decreasing the oil viscosity. [27][28][29] This work aims to contrast the theoretical results reported in previous work 11 and the experimental results concerning the efficiency of the materials to improve the fluid flow through porous media.…”

In this work, the effect of distilled water, a biodiesel viscosity reducer, and a commercial nonionic surfactant on the apparent permeability of clay-sand cores through the analysis of contact angle, linear swelling, and porous media fluid flow for a northern Mexico crude oil was evaluated. The results showed that the clay content influences the contact angle values having a lower wettability effect in the rocky medium. The addition of biodiesel produces a fluid movement similar to the addition of distilled water. Biodiesel-based flow enhancer not only reduces the crude oil viscosity but also improves the flowability through porous media. However, this behavior is only valid if the soil is not saturated with salty water.

Despite the substantial advancement in developing various hydrogel microparticle (HMP) synthesis methods, emulsification through porous medium to synthesize functional hybrid protein–polymer HMPs has yet to be addressed. Here, the aided porous medium emulsification for hydrogel microparticle synthesis (APME‐HMS) system, an innovative approach drawing inspiration from porous medium emulsification is introduced. This method capitalizes on emulsifying immiscible phases within a 3D porous structure for optimal HMP production. Using the APME‐HMS system, synthesized responsive bovine serum albumin (BSA) and polyethylene glycol diacrylate (PEGDA) HMPs of various sizes are successfully synthesized. Preserving protein structural integrity and functionality enable the formation of cytochrome c (cyt c) – PEGDA HMPs for hydrogen peroxide (H2O2) detection at various concentrations. The flexibility of the APME‐HMS system is demonstrated by its ability to efficiently synthesize HMPs using low volumes (≈50 µL) and concentrations (100 µm) of proteins within minutes while preserving proteins’ structural and functional properties. Additionally, the capability of the APME‐HMS method to produce a diverse array of HMP types enriches the palette of HMP fabrication techniques, presenting it as a cost‐effective, biocompatible, and scalable alternative for various biomedical applications, such as controlled drug delivery, 3D printing bio‐inks, biosensing devices, with potential implications even in culinary applications.
