SUREMUL

SUREMUL primary emulsifier is used in conjunction with the SUREWET RHELIANT system invert-emulsion system surfactant. The SUREMUL emulsifier can also be used in other invert-emulsion systems in conjunction with a secondary emulsifier or a wetting agent.

Applications

SUREMUL emulsifier is designed for use as the primary emulsifier in invert emulsion systems to provide a stable emulsion and excellent oil wetting. SUREMUL emulsifier contributes to HPHT filtration control and to the temperature stability of the system. It is effective over a wide temperature range and in the presence of contaminants. SUREMUL emulsifier exhibits minimal dispersion tendencies when drilling reactive formations.

Initial system formulations typically require 6 to 10.2 lbm/bbl [17 to 29 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].

For high-temperature applications [temperatures >300 degF [150 degC], initial system formulations require 8.75 to 14.0 lbm/bbl [25 to 40 kg/m³].

Advantages

• Improves emulsion stability
• Functions as a secondary wetting agent
• Provides filtration control
• Minimizes dispersion tendencies of reactive clay solids
• Helps maintain HPHT filtrate in a water-free state
• Improves thermal stability and contamination resistance

Toxicity and handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the safety data sheet (SDS).

Packaging and storage

SUREMUL emulsifier is packaged in 55-galUS [208-L] drums and 257-galUS [1,000-L] totes. Store in a dry, well-ventilated area. Keep container closed. Keep away from heat, sparks, and flames. Store away from incompatibles.
