Barite or Bartyes is high-quality Barium Sulfate (BaSO4) micronized to meet the API 13A specifications used to increase mud density in all types of oil or water-based drilling fluid systems. Emprada products are chemically inert to all drilling fluids additives, which are mostly used as high-quality weighting agents.

able drilling fluid for a given reservoir may be critical (Al-Hitti et al. 2005). Many researchers proved the effects of drilling fluids on petrophysical properties due to the selection of unsuitable mud. Selection of the proper drill-in-fluid (DIF) composition was considered key for mini-mizing drilling problems and obtaining desired productiv-

A Barite plug is a barite slurry pumped down the drill pipe and placed at the bottom of the wellbore. A successful Barite plug should accomplish two things: Initially, the weight of the barite slurry should kill the well. After some time, the settled barite plug should mechanically block any flow up the wellbore.
