DEEP CLEAN Drilling Fluids Cleaner
Rxsol Deep Clean combines the dissolving capacity of powerful hydrocarbon solvents with the water-wetting capability of optimized Hydrophile-Lipophile Balance (HLB) surfactants, creating a double emulsion.
Application & Uses
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.

Product Description & Chemical Profile
Very effective for cleanup during the displacement of oil or synthetic base drilling fluids prior to the start of completion operations.
Rxsol Deep Clean combines the dissolving capacity of powerful hydrocarbon solvents with the water-wetting capability of optimized Hydrophile-Lipophile Balance (HLB) surfactants, creating a double emulsion. The Deep Clean product satisfies all the requirements of a multiple-stage displacement wash train with just one product. This efficient combination of powerful solvents, surfactants and water-wetting agents not only provides excellent surface cleaning, but does so with a good-to-very-good HSE profile. When used in wellbore-cleaning operations, its double emulsion performs the task of thinning, dissolving and dispersing oil/synthetic-base-mud residue, while leaving all downhole tubulars and metal surfaces in a water-wet state.
