  • Wellbore fluids for use downhole
    Patent number: 10253234
    Abstract: A wellbore fluid may include a base fluid, and a ground weight material comprising barite and quartz and having a d50 between about 4 and 8 microns and a d90 between about 15-25 microns. The ground weight material of the wellbore fluid may have a specific gravity of less than or equal to about 4.2.
    Type: Grant
    Filed: July 29, 2016
    Date of Patent: April 9, 2019
    Assignee: M-I L.L.C.
    Inventors: Chemsseddine Bouguetta, Roger Wayne Matlock, Henry Lee Conn, Robert Bailey, James Friedheim
  • Methods of pneumatically conveying solid particulates
    Patent number: 10093844
    Abstract: A method for transferring barite for use in wellbore fluids may include providing a ground weight material comprising barite and quartz having a d50 between about 4 and 8 and a d90 between about 15-25 microns to a pneumatic transfer vessel, supplying an air flow to the ground weight material in the pneumatic transfer vessel, and pneumatically transferring the ground weight material from the pneumatic transfer vessel to a storage vessel.
