Rosfloc DET is an aqueous blend of nonionic surface-active agents and functional additives. It is designed to reduce the surface tension of all water-base mud systems and reduce the sticking tendency of water-sensitive shale cuttings.

Application

Rosfloc DET has application in all drilling areas and can be used in virtually any water-base drilling fluid. It is used primarily in upper-hole drilling to minimize bit and Bottom-Hole Assembly (BHA) balling, reduce surface tension, and aid in dropping sand and the removal of drill solids. It may be used as an emulsifier at any point in the drilling operation to improve emulsification of oil and reduce the viscosity of oilcontaminated fluids. Rosfloc DET frequently reduces torque and drag, even when no oil is present in the system. Normal treatments range from 0.3 to 0.8 kg/m3 and provide satisfactory performance under most conditions. In severe gumbo shale areas, 10 to 20 kg/m3 concentrations of Rosfloc DET are recommended to minimize bit and BHA balling; higher concentrations may cause foaming and require a defoamer. Rosfloc DET is effective in all water-base systems including freshwater, brackish water, seawater and saturated saltwater fluids.

Physical properties

Low-viscosity transparent liquid.

  • Dosage of 1-3 kg/m3 of drilling mud
  • pH (1% solution): 6.0 – 10.0
  • Solubility: 100% soluble in water
  • Freezing point: -20°С

Chemical properties

Oxyethylated alcohols with functional additives.

Advantages

  • Minimizes bit and BHA balling
  • Reduces the surface tension of the liquid phase, helping to drop sand and remove drill solids
  • Improves water-wetting action on all solids and reduces the sticking tendency of reactive shale cuttings
  • Effective in all water-base muds

Packaging

Rosfloc DET is supplied in plastic jugs or metal drums by agreement with the client.

Safety requirements

According to acute toxicological characteristics, as per GOST 12.1.007-76, Rosfloc DET refers to the 3rd class of hazard – low-hazard chemical substances. It poses no hazard of acute inhalation intoxication. In case of contact it irritates conjunctiva and skin cover. Rosfloc PG is fire-flame-proof.

Transportation

Rosfloc DET is transported by all the type transport according to the rules of cargo transportation.
