KCl Substitute


SKL-100T™ is a liquid substitute for Potassium Chloride (KCl) for use in clear brine WO and completion fluids.


  • Prevents clay swelling and migration
  • Non-flammable
  • Used with water, brines, acids and drilling fluids
  • Compatible with most gels, cross linkers, and breakers
  • Will not adversely effect fluid pH
  • Superior performance at lower costs than KCl
  • Minimizes inventory, storage and transportation problems
  • Minimizes waste disposal problems
  • Can be mixed on-the-fly
  • No inorganic chlorides
  • Slightly cationic
  • Exceeds KCl performance as per CST and reverse permeability testing
  • Use in preflush fluids and most completion fluids


1⁄2 gal SKL-100TM per 1,000 gal water or 2 gal SKL-100TM per 100 barrels water.


SKL-100™ can be mixed with water or other process and treatment fluids in a tank truck, blend or storage tank or on the fly.

  • Potassiumchloride(KCL)isgenerallyusedatatwo(2)percent concentration although it is common to use much higher concentrations depending on the clay content and the clay characteristics
  • A two (2) percent solution requires approximately 700 pounds of KCL per 100 barrels of water (about 14 fifty (50) pound bags or 13 twenty-five (25) kilogram bags).
  • In order to obtain the equivalent performance of KCL, two (2) gallons of SKL–100TM are used per 100 barrels of water or per every 700 pounds of KCL. One drum of SKL–100TM will replace about 20,000 pounds of KCL or 400 fifty pound bags.
  • The amount of KCL used is also dependent (or should be) on the purity of the KCL. This factor is all too often overlooked when mixing KCL to the required concentration.
  • Large cost savings can be generated when using SKL–100TM in replacing KCL in terms of freight savings, warehousing, inventory, blending manpower costs, on-the-fly savings when local water sources are available, maintenance costs savings on equipment such as pumps due to damage caused by the various granular materials in the KCL.
