4.1-SG barite and 7% 4.7-SG alternative material was required to achieve the desired 4.2-SG weight material blend. Different blend ratios were also tried using barite with a density lower than 4.1 SG. For instance, the blend ratio became 50/50 when using 3.9-SG barite. In order to observe more impact from the weighting agent

What is the specific gravity of mud? The specific gravity of mud can vary depending on its composition. Water-based drilling mud typically has a specific gravity close to 1.0, while weighted muds (with additives like barite) can have specific gravity values ranging from 1.2 to 2.4 or more. What is the specific gravity of drilling mud?
