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.
