  • Methods and compositions using a combination of zwitterionic surfactants and gemini surfactants as diversion agents
    Patent number: 11236264
    Abstract: A wellbore fluid may include a gemini surfactant, a zwitterionic surfactant; an activator, and an aqueous base fluid. The gemini surfactant may have a structure represented by formula (I): where R1 is a C1-C6 hydrocarbon group or a monovalent cation, R2 is a C1-C10 hydrocarbon group, m is an integer ranging from 1 to 4, n is an integer ranging from 8 to 12, and X is a monovalent anion.
    Type: Grant
    Filed: June 8, 2020
    Date of Patent: February 1, 2022
    Assignees: SAUDI ARABIAN OIL COMPANY, KING FAHD UNIVERSITY OF PETROLEUM & MINERALS

  • METHODS AND COMPOSITIONS FOR DOWNHOLE DIVERSION OF WELL TREATMENT FLUID
    Publication number: 20210380867
    Abstract: In one aspect, embodiments disclosed herein relate to wellbore fluids that include a surfactant, calcium chloride, and an aqueous base fluid. The surfactant may have a structure represented by formula (I): where R1 is a C15-C27 hydrocarbon group, R2 is a C1-C10 hydrocarbon group, and n and m are each, independently, an integer ranging from 1 to 4. The wellbore fluid may contain the calcium chloride in an amount of 5% by weight (wt. %) or more, relative to the total weight of the wellbore fluid.
