Halliburton has been granted a patent for a method of treating wells using a specialized treatment fluid. This fluid is composed of a furan-based polymer, a Bronsted acid, an anhydride or dibasic ester, a quaternized wetting agent, and a docking agent, which is then introduced into the wellbore for operations.

Well treatment fluid composition and method
The patent US12043798B1 outlines a method for treating a well using a specialized treatment fluid. This method involves preparing the treatment fluid at the surface by combining several components, including a furan-based polymer, a Bronsted acid, an anhydride or dibasic ester, a wetting agent (which may consist of a quaternized alkyl amine salt or a quaternized polyamine salt), and a docking agent selected from a specific group of silanes. Once prepared, the treatment fluid is introduced into the wellbore to perform various wellbore operations. The claims specify that the method can be applied in wellbores with temperatures ranging from approximately 65°F to 200°F and may involve coating the treatment fluid on a proppant prior to its introduction.
Additionally, the method allows for the treatment fluid to be introduced into fractures within a subterranean formation from the wellbore, facilitating contact with a proppant located in those fractures. The wellbore operations can include pumping the treatment fluid through a gravel pack. The Bronsted acid component can be selected from a wide range of acids, including hydrogen bromide, sulfuric acid, and various sulfonic acids, among others. Furthermore, the anhydride or dibasic ester component can include a diverse selection of compounds, such as furan-2,5-dione and various dicarboxylic anhydrides. This comprehensive approach aims to enhance the effectiveness of well treatment processes in various geological conditions.
