POTASSIUM CHLORIDE (KCl) is a soluble salt that is an extremely efficient shale stabiliser when drilling hydro sensitive clays and shales. Inhibition is provided through ion exchange; the potassium ion enters between the individual clay platelets in the shale so that they are held together, thus eliminating entry of water from the drilling fluid.
The SAND CONTENT KIT is a simple and accurate sieve analysis tool used to determine the sand content of drilling fluids.
SODA ASH is a free flowing powder also known as sodium carbonate (Na2CO3) used in a fluid system to precipitate calcium (hardness) and increase alkalinity (pH).
Sodium Chloride (NaCl) is a widely available commercial chemical that can be used as a weighting agent to increase fluid density up to 1.2sg (10lb / gal). It is predominately used for formulating clear, solid free work-over and completion fluids. Sodium chloride can also provide inhibition to formations containing water sensitive clays and shales.
