A wellbore drilling assembly may include a pump in fluid communication with a wellbore via a feed pipe; and a wellbore fluid disposed in at least one selected from the group consisting of the pump, the feed pipe, the wellbore, and any combination thereof, wherein the wellbore fluid comprises a base fluid and a wellbore additive. In some instances, a wellbore additive may include first mineral particles having a specific gravity of about 2.6 to about 20; second mineral particles having a specific gravity of about 5.5 to about 20; lubricant particles having a specific gravity of about 2.6 to about 20; wherein the first mineral particles, the second mineral particles, and the lubricant particles are different; and wherein the first mineral particles, the second mineral particles, and the lubricant particles have a multiparticle specific gravity of about 3 to about 20. |
