Alco Chemical has developed specialty polymer products that have been designed and tested specifically to meet the needs of the oilfield market. These products include:
ALCOCLEAR™ water clarifier additives - synthetic HMW polyamine additives for high salinity brines and high temperatures.
ALCODRILL™ mud thinners - high temperature rheology control agents for aqueous bentonite containing drilling muds.
ALCOFLOW® scale inhibitors - unique and patented products suitable for topside and squeeze applications, high salinity, high temperature and challenging environments.
FLOC AID™ water clarifier additives - amphoteric synthetic polymers for high salinity brines and difficult emulsions.
VERSA-TL® Sulfonated Polymers - superior drilling mud deflocculant products. This unique range of sulfonated-styrene homopolymers and maleic acid-containing copolymers offer superior calcium and salt tolerance and extreme high temperature stability.
