PAL DD TECH 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 cuttings.
Typical Physical Properties
Physical Appearance Light Blue-Green Liquid
Specific Gravity 1.01 - 1.02
PH (1% Solution) 7.5 -8.5
Solubility in Water Soluble
PAL DD TECH 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 oil‐contaminated fluids.
PAL DD TECH is effective in all water‐base systems including fresh water, brackish water, seawater and saturated saltwater fluids.
PAL DD TECH 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 PAL DD TECH are recommended to minimize bit and BHA balling;
higher concentrations may cause foaming and require a defoamer.
Packing and Storage
PAL DD TECH surfactant is packaged in 5‐gal (18.9‐L) cans and 55‐gal (208‐L)drums. Store in a dry location away from sources of heat or ignition.
