  • Self-suspending modified proppant system for carbon dioxide based fracturing fluids
    Patent number: 10131833
    Abstract: Self-suspending proppants including proppant particles coated with a CO2-philic coating are provided. The CO2-philic coating may be lightly crosslinked and may have a physical structure that constrains CO2 molecules. Methods of making self-suspending proppants may include coating a proppant particle with a polymerizable precursor material of a CO2-philic material and polymerizing the polymerizable precursor material to form a self-suspending proppant are also provided. Additionally, hydraulic fracturing fluids that may include a CO2-based fluid and the self-suspending proppants and methods of treating subterranean formations by contacting a subterranean formation with hydraulic fracturing fluid and propagating at least one subterranean fracture are provided.
    Type: Grant
    Filed: March 15, 2018
    Date of Patent: November 20, 2018
    Assignees: Aramco Services Company, Research Foundation of The City of New York
    Inventors: Feng Liang, Ghaithan A. Al-Muntasheri, Leiming Li, B. Raghava Reddy, George John, Vidyasagar Adiyala
