The goal of this project is to address the lack of effective, reliable viscosifiers and focus on the development of novel, dynamic binary complexes (DBCs) to achieve reversible super-adjustable viscosities and implement these novel additives in fracturing fluids.

One of the most important components of a hydraulic fracturing fluid is the viscosity modifying agent, which prevents settling and non-uniform distribution of proppant, and provides a strong driving force on proppant to follow the fluid into cracks, fractures, and fissures. Without viscosifying agents, it is impossible to adequately transport proppant from the surface to the fissures. Currently, one line of thinking is that the lack of effective, reliable viscosifiers is a critical limiting factor causing sub-optimal permeability and relatively low productivity index in shale reservoirs even when other steps of hydraulic fracturing are successfully executed. This project is aimed at addressing this limitation and focuses on the development of novel, dynamic binary complexes (DBCs) to achieve reversible super-adjustable viscosities and to implement these novel additives in fracturing fluids.
From an engineering perspective, the development of super-adjustable viscosifying agents may be beneficial in the context of enhancing proppant transport into fractures and reducing damage to proppant pack. These advances will eventually lead to improvements in productivity index of fossil fuel from unconventional reservoirs. It is anticipated that aside from their impact on fracturing technologies for unconventional reservoirs, these materials may be beneficial for enhanced oil recovery applications from conventional reservoir as well.
