Specific Gravity Drilling Fluids Netwas Group Oil

The density of any material is derived by multiplying the specific gravity of that material by the density of pure water For example, the specific gravity of barite is 42 and its density is equal to (42) (833 lb/gal) = 35 lb/gal Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure waterI = Starting Volume of Mud, gallons W f = Desired Mud Weight, lb/gal W I = Starting Mud Weight, lb/gal Rule of Thumb: For Weighted Drilling Fluids up to 12 lbs/gal using Barite For every 140 pounds of Barite added to 100 gallons (US) the weight will rise 1 lb/gal Prior to weighting up fluid the Funnel Viscosity must be raised with AQUAGEL® or QUIKGEL® to four times the final mud weight WeightUp Calculation with BariteIn the ground under high pressure, the need to increase the proportion of mud, barite powder added to the slurry is an effective measure to increase the proportion of mud Barite used in drilling mud to do the general fineness of 325 or more to achieve, such as the fineness of barite precipitation is easy enough Requirements with the barite drilling mud weight is greater than 42, BaSO4 density barite, density barite Suppliers and Manufacturers
