The methylene blue capacity of a drilling fluid is an indication of the amount of reactive clays (bentonite or drilled solids) present as determined by the methylene blue test (MBT). The methylene blue capacity gives an estimate of the total cation exchange capacity (CEC) of the solids in the drilling fluid. The methylene blue capacity and the cation exchange capacity are not necessarily equivalent, with the methylene blue capacity normally being somewhat less than the actual cation exchange capacity. Methylene blue solution is added to a sample of drilling fluid which has been treated with...

Hot Plate 1. Make sure the hot plate is rated for the proper voltage before plugging it in. 2. Make sure the electrical cord is in good condition and equipped with a grounding plug. 3. Do not leave the hot plate unattended while heating. 4. Use caution while handling hot flasks and other laboratory containers. Chemicals The chemicals used in this kit (methylene blue solution, hydrogen peroxide 3%, and sulfuric acid 5N), are hazardous to your health. Avoid direct contact, inhalation, and ingestion. Keep away from fire and other heat sources. Read all warnings, precautions, and hazard...

1. With the syringe, add 2.0 mL of drilling fluid to the erlenmeyer flask. Air or gas entrained in the drilling fluid must be removed prior to injection. Vigorously stir the drilling fluid to break the gel and quickly draw the mud into the syringe. Then slowly discharge the syringe back into the drilling fluid keeping the tip submerged. Again draw the fluid into the syringe and deliver exactly 2.0 mL of fluid to the flask. If less than 2.0 mL or more than 10.0 mL of methylene blue solution will be required, the volume of drilling fluid sample may be increased or decreased to a more...

Methylene Blue Capacity = The methylene blue capacity may also be reported as pounds per barrel of equivalent bentonite, based on bentonite with a cation exchange capacity Bentonite equivalent (Ib/bbl) = Dri||ing Fluid (mL) Bentonite equivalent (kg/m3) = 2.85 x Bentonite equivalent (Ib/bbl)

Methylene Blue is a dye, and if allowed to dry on glassware or other laboratory equipment, will cause a stain that is difficult or impossible to remove. 1. Avoid spilling methylene blue. 2. Thoroughly wash and dry all laboratory equipment and glassware immediately after use. 3. Make sure methylene blue bottles are closed tightly after use.
