PRODUCTS TECHNICAL DATA
PRODUCT NAME :Asphaltic fluid loss control agent,MENEX
COMPOSITION / INFORMATION ON INGREDIENTS AND APPLICATIONS
The primary functions is to improve both API and HPHT fluid loss while providing rheology stability over a wide range of temperatures. Another functions as a shale stabilizer and has a broad PSD for sealing micro-fractures. It functions well in the presence of common mud contaminants such as calcium, magnesium and chloride salts and also across a wide range of pH alkalinities.
Asphaltic fluid loss control agent,MENEX is principally used in higher temperature applications up to 400°F (204°C) to replace basic polymer filtration control additives which lose their functionality at elevated wellbore temperatures additive. It is useful to assist in controlling shale stability and hole washout.
Benefits:
● Stabilizes and extends the temperature limitations and contamination resistance of water-base mud systems to above 200°C
● Controls fluid loss in basically all water-based drilling fluids
● Controls shale stability
● Does not increase rheology
● Has higher temperature performance limits than CMC, PAC, or starches
● Its effective same as Sulfonated Asphalt or lignite, but doesn’t contaminate the formation
● Its effective in high-density drilling fluids where fluid-loss control can be achieved without increasing the viscosity.
Applications: should be used to reduce and maintain low fluid loss in all water-based systems at all densities and will improve the performance of water-based drilling fluids.Asphaltic fluid loss control agent,MENEX additive will not increase viscosity but will stabilize the fluid at increased bottomhole conditions while controlling high-temperature, high-pressure filtration rates. MENEX additive is useful to assist in controlling shale stability and hole washout.
It should be used at concentrations of 5.7 to 22.8 kg/m3 for fluid loss control. For increased bottomhole temperatures, use larger concentrations depending on drilling conditions.
Apperance: Black free flowing powder or suspending liquid.
Ph : 8.8-9.2
Density:0.85-0.95
