Short Term Clay Control
Op-T-Con CS-3001 is a specialized liquid product designed specifically for use as a replacement for bagged potassium chloride (KCI). It provides excellent shale and clay control without the logistics, handling and mixing problems associated with large volumes of bagged KCI. Op-T-Con CS-3001 is compatible with all gels, crosslinkers and breaker systems typically utilized in well drilling, stimulation and work over operations. It will not affect fluid pH and being non surface active does not adversely affect formulation wet-ability or create any type of a foaming problem. Op-T-Con CS-3001 may be used in fresh water, acid or brine systems and will not hinder the performance of acid corrosion inhibitors.
While the product does not contain any potassium, Op-T-Con CS-3001 is composed of a sophisticated, mildly cationic complex that functions as KCI to control shale and clay hydration. Op-T-Con CS-3001 may be easily utilized in “on the fly systems “to eliminate pre-mixing and leftover brine disposal problems. If the product is mixed in fresh water and no salts are added, the fluid can be easily disposed of without adverse effect on the environment. A 2% KCl equivalent solution of Op-T-Con CS-3001 contains only 165 mg/L chloride ion. This significantly reduces the risks associated with the use of KCI fluids. Op-T-Con CS-3001 is effective for the smectite, illite and mixed layer clay minerals, those commonly found in shale formations.
