  • High density brine with low crystallization temperature
    Patent number: 11667826
    Abstract: A wellbore fluid comprising a first aqueous base fluid and a plurality of silica nanoparticles suspended in the first aqueous base fluid. The nanoparticles are present in the fluid in an amount to have an effect of decreasing a crystallization temperature by at least 4 to 55° F. as compared to a second aqueous base fluid without the silica nanoparticles.
    Type: Grant
    Filed: October 14, 2021
    Date of Patent: June 6, 2023
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Hui Joyce Zhang, Xia Wei, Steven Young

  • High temperature viscosifier for insulating packer fluids
    Patent number: 10337289
    Abstract: An insulating packer fluid including an oleaginous fluid and a styrenic thermoplastic block copolymer and methods of preparing the packer fluid are provided. Also provided are methods of using the insulating packer fluid that include pumping an insulating packer fluid into an annulus formed between two concentric strings of pipe extending into a wellbore.

  • Colloidal silica and polymer system for insulating packer fluids
    Patent number: 10273400
    Abstract: Insulating packer fluids containing colloidal silica inorganic additives may be used in methods that reduce convective currents in a packer fluid. In other aspects, packer fluids containing colloidal silica inorganic additives may be used in methods of insulating production wells and methods for stimulating production of hydrocarbons.
