“…Thus, the carboxyl groups can be crosslinked with metal ions (e.g., Cr 3+ and Al 3+ ) to form ionic-bonded gels. The first in situ crosslinked gel system for profile control was prepared by Philips (now ConocoPhillips) in the 1970s using partial HPAM with aluminum citrate [ 26 , 27 ]. Sharma et al compounded halfway HPAM polymers with a chromium acetate derivative to prepare a chromium ion-crosslinked gel water shutoff system suitable for medium-temperature reservoirs [ 2 ].…”

Polymer gels with suitable viscoelasticity and deformability have been widely used for formation plugging and lost circulation control, profile control, and water shutoff. This article systematically reviews the research progress on the preparation principle, temperature resistance, salt resistance, and mechanical properties of the ground and in situ crosslinked polymer gels for oil-gas drilling and production engineering. Then, it comparatively analyzes the applicable conditions of the two types of polymer gel. To expand the application range of polymer gels in response to the harsh formation environments (e.g., high temperature and high salinity), we reviewed strategies for increasing the high temperature resistance, high salt resistance, and rheological/mechanical strengths of polymer gels. This article provides theoretical and technical references for developing and optimizing polymer gels suitable for oil-gas drilling and production.

“…The residual resistance factor, defined as the quotient of the mobility of the fluids before and after the treatment, presented high values (> 10) in high-permeability cores using low polymer concentrations (250 ppm) in conjunction with various concentrations of trivalent ions. Therefore, most of the gels reported in the literature are PAM-based or AM-based copolymers with inorganic crosslinkers such as Cr(III) salts [87][88][89][90][91][92]. Al(III), among others, has been used to form an inorganically cross-linked gel system; these gels are the result of ionic bonding between the negatively charged carboxylate groups and positively charged polyvalent ions [93].…”

Water Control with Gels Based on Synthetic Polymers under Extreme Conditions in Oil Wells

A bibliographic review of research works dealing with gels based on synthetic polymers and their application in water control under harsh conditions was compiled. The extreme conditions were defined to be above 100 °C with 100 000 ppm of total dissolved solids, including divalent ions. Works describing laboratory experiments and oilfield implementations were also considered. According to current literature, some gels based on synthetic polymers have displayed desirable properties for water control, but in many cases, research is still at laboratory level. Therefore, further studies are required to understand the mode of action and stability of gels and polymers submitted to hard conditions in order to produce high‐performance prototypes.

“…Polymeric materials with hydrophobic properties have also attracted attention for their effectiveness at separating oils and organic solvents from water. [158][159][160][161][162] Polymer-based materials are also inexpensive to manufacture, can assume various forms, including sponges, [163][164][165][166][167] powders, [168][169][170] pads, and booms and have easily transformable surface characteristics. Among them, sponge-type sorbents are usually manufactured as a polyurethane (PU) based sponge and are already in wide use as oil sorbents for their high porosity, high resilience, low density, high adsorption, and easily-scalable fabrication.…”

The conservation of ocean and freshwater have been crucial issues over the past decades, and oil/water separation is a well‐known technology to restore polluted water systems. In the meantime, oil sorbents serve as a promising means of achieving water conservation to recover from oil spills, which require a multi‐factorial approach to review high selectivity, capacity, and rate of oil recovery. However, reusability is a critical component to consider in incidents with large‐scale spills. With the development of sorbent technology, some studies have progressed to explore surface engineering and material design for high oil sorption capacity and durability. Thus, this systemic review, a summary of sorbent developments, serves as a guide to understanding practical applications that can apply to large‐scale oil spills and recognize remaining issues. In this review, the oil weathering process and oil sorption mechanisms in relation to the characteristics of target pollutants are introduced. Then, this comprehensive review focuses on materials in advanced sorbents. These materials have properties including, aligned channels for fast sorption, self‐heating capabilities for viscous oil cleanup, and magnetic‐responsiveness to enhance a collection of final products. The perspective and challenges for the next generation of oil spills remediation technology‐based oil sorbents materials are finally presented in the last section.
