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 d50 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. L'invention concerne un procédé de transfert de baryte, destiné à être utilisé dans des fluides de puits de forage qui peut comprendre l'apport d'un matériau de lest broyé comprenant du baryte et du quartz ayant un d50 compris environ 4 et 8 et un d50 compris entre environ 15 et 25 microns vers un récipient de transfert pneumatique, l'apport d'un flux d'air au matériau de lest broyé dans le récipient de transfert pneumatique, et le transfert pneumatique du matériau de lest broyé du récipient de transfert pneumatique vers un récipient de stockage.
