 — Here are some of the primary application areas and uses of barite: 1. Oil and Gas Industry: Drilling Fluids: Barite is commonly used as a weighting agent in drilling fluids used in oil and gas exploration. By adding barite to drilling mud, it increases its density, helping to control wellbore pressure and prevent blowouts.

 — Abstract. Oil-based mud (OBM) is the first choice for complex deep wells due to its advantages of high-temperature resistance, good lubrication and borehole stability. But barite sagging under ultra-high temperature during the long-time stationary completion operation may lead to serious problems in ultra-deep wells, for instance, pipe …

Nearly 98% of the barite used in the United States is as a weighting agent in oil- and gas-well drilling fluids. Because it significantly reduces X-rays (looks opaque on X-ray film), barium is used in medicine to diagnose gastrointestinal problems. ... By far, the principal use for barite is as a "weighting agent" in oil and natural gas ...

 — Sagging of particles is one of the most critical issues when drilling deep oil and gas wells especially when the hole angle is greater than 30°. Accumulation of cuttings at the bottom of the hole around the drilling bit as a result of barite sagging cause severe problems such as the loss of well control. Temperature has a major effect on barite …
