Rxsol Deep Clean additive is designed primarily for down hole use in oil and gas wells for cleanup during the displacement of oil or synthetic base drilling fluids prior to the start of completion operations. The Rxsol  recommends concentrations of 5 – 20% (v/v) in the main cleanup pill,pumped in turbulent flow. The combined action of the solvents and surfactants with the double emulsion in Deep Clean product provides efficient cleanup of solids and drilling-fluid residue during displacement operations and leaves all downhole tubulars in a water-wet state -without the need for a subsequent surfactant wash.

The Rxsol Deep Clean additive functions in freshwater, seawater, and high-density brines. Under static conditions, the solvent fraction will eventually phase separate. Mild agitation is required before pumping. The product can also be incorporated into a high-viscosity pill to aid in the removal of heavy solids prior to pumping the main cleanup pill or as a high-viscosity displacement aid that follows the main cleanup pill.
 

The exact product concentration and spacer/wash volumes will vary depending on mud type and wellbore conditions. Recommendations for a specific application should be made after consulting Rx Marine representatives.
