Riteks Clay Stop is an improved modified choline chloride product for use as a liquid potassium chloride (KCl) substitute in drilling, stimulation and completion fluids. It has the ionic balance required to provide clay control protection in the reservoir, performing as well as choline chloride by itself and at a cost savings.
Clay contains cations, typically sodium, within their crystalline layers that occupy base exchange positions or sites in the flay structure. Upon contact with water, these cations are solubilized resulting in clay instability and swelling. When clays swell, the permeability of the formation is diminished which impedes production. Clay stabilizers reduce clay swelling through ion exchange, where the clay stabilizer provides a cation to replace the native, solubilized clay cation, sodium.
