Drlg Detergent

DRLG DetergentD-D drilling detergent is an aqueous blend of surface-active agents. It is designed to reduce the surface tension of all water-base mud systems and reduce the sticking tendency of water-sensitive shale cuttingsTypical Physical PropertiesPhysical appearance- Light blue greenliquidSpecific gravity- 1.01-1.02pH (1% solution)- 7.5-8.5Solubility in water- 100%Freezing point- 32OF (0OC)ApplicationsD-D 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. D-D frequently reduces torque and drag, even when no oil is present in the system. Normal treatments range from 0.1 to 0.2 lb/bbl (0.29 to 0.57 kg/m3) and provide satisfactory performance under most conditions. In severe gumbo shale areas, 4 to 6 lb/bbl (11.4 to 17.1 kg/m3) concentrations of D-D are recommended to minimize bit and BHA balling; higher concentrations may cause foaming and require a defoamer.  D-D is effective in all water-base systems including freshwater, brackish water, seawater and saturated saltwater fluidsAdvantagesMinimizes bit and BHA ballingReduces the surface tension of the liquid phase, helping to drop sand and remove drill solidsImproves water-wetting action on all solids and reduces the sticking tendency of reactive shale cuttingsFunctions as an emulsifier,reducing the viscosity ofoil-contaminated fluidsEffective in all water-base mudsLimitationsThe freezing point of D-D is 32OF (0C). D-D CWT, a special coldweather formulation with a freezing point of -29OF(-20OC), is available.Toxicity and HandlingBioassay information is available on request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the  Transportation and Material Safety Data Sheet (MSDS). Fluids containing high concentrations of D-D may not be suitable for discharge into all marine environmentsPackaging and StorageD-D is a liquid packaged in 5-gal (18.9-l) cans and 55-gal (208.2-l) drums. International packaging may vary. Store in a location away from sources of heat or ignition.
