  • Patent number: 11980875
    Abstract: A method for making a magnetic-nanoparticle-supported catalyst includes reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a phosphine group, an amine group and at least one hydroxyl group; anchoring the ligand to a surface of magnetic nanoparticles via an oxygen atom of the hydroxyl group to form a ligand complex; combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-particle-supported catalyst. The magnetic-particle-supported catalyst is a Rh complex of magnetic-Fe3O4-nanoparticle-supported ferrocenyl phosphine catalyst.

  • Patent number: 11566167
    Abstract: Amidoamine-based gemini surfactants having dual chains connected via an alkenylene or alkynylene linker. Each chain contains a quaternary ammonium head group and an ethoxylated alkyl tail. A water-based drilling fluid containing the gemini surfactant is also provided. As examined by linear swelling and free swelling tests, the gemini surfactant is effective in reducing clay swelling.

  • Patent number: 11447688
    Abstract: Methods of controlling clay swelling and stabilizing subterranean geological formations containing swellable clays (e.g., montmorillonite, bentonite) are described. The methods involve treating the swellable clays with a composition containing an amidoamine-based gemini surfactant. The gemini surfactant has dual chains connected via an alkylene linker, whereby each chain contains a quaternary ammonium head group and an ethoxylated alkyl tail. As examined by linear swelling and free swelling tests, use of the gemini surfactant is effective in reducing swelling of the clays.

  • Patent number: 11407928
    Abstract: A drilling fluid formulation which includes an aqueous phase, and additives including an organophilic clay, a gemini surfactant, and a polyacrylamide. The organophilic clay contains an ion-exchange reaction product of a clay material (e.g. smectite) and quaternary ammonium cations. The polyacrylamide contains reacted units of an acrylamide monomer, an acrylate monomer, and a hydrophobicity modifying monomer. Rheology properties of the drilling fluid including gel strength, yield stress, and storage modulus are specified. The additives present in the drilling fluid synergistically boost its shale swelling inhibition capability.
