Flat rheology drilling fluid system
Optimize ECD, reduce barite sag and losses, and enhance ROP.
The RheMul flat rheology primary emulsifier provides excellent emulsion stability, aids in preferential wetting of solids by the continuous phase, and facilitates HPHT filtration control and temperature stability.
The RheMul emulsifier is designed for use as the primary emulsifier in the RheGuard system to provide a stable emulsion and secondary oil wetting. It is effective in the presence of contaminants and over a wide range of densities and temperatures. It exhibits minimal dispersion tendencies when drilling reactive formations. The RheMul emulsifier is used in invert-emulsion drilling fluids to enhance the emulsion characteristics.
Initial system formulations typically require 8 to12.5 lbm/bbl [22.8 to 35.7 kg/m3] depending on the desired properties and other components in the system. Daily treatments are usually in the range of 0.1 to 1 lbm/bbl [0.3 to 2.85 kg/m3].
A designated primary wetting agent may be required in higher densities and for HPHT applications.
Bioassay information is available upon request. Handle in accordance with good industrial hygiene and safety practices. Wear personal protective equipment. Ensure adequate ventilation. Avoid breaking vapors or mists. Avoid contact with skin, eyes, and clothing. Keep away from heat, sparks, and open flame. Take precautionary measures against static discharges. Avoid static electricity buildup with connection to earth.
The RheMul emulsifier is available in 55-galUS [208-L] drums and 550-galUS [2,131-L] totes. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking. Keep containers tightly closed in a dry, cool, and well-ventilated place. Store in original container, and avoid heat, flames, and other sources of ignition.
