Product Sheet: BRIGHT GLIDE Water-Soluble Brine Lubricant

Date: 1/12/2017

The BRIGHT GLIDE water-soluble brine lubricant is specially designed for use in potassium formate brines to reduce the coefficient of friction. This lubricant demonstrates exceptional metal-to-metal friction reduction when added to potassium formate fluids at low concentrations. Normal concentrations are in the range of 7 to 10.5 lbm/bbl [20 to 30 kg/m3]. In addition to potassium formate, the lubricant is highly effective at low concentrations in drillwater, seawater, sodium chloride, sodium bromide, and calcium bromide brines; however, it is not intended for use with calcium chloride brine. Formulated not to form emulsions in oil-contaminated brines, the lubricant also will not form insoluble grease. Although the lubricant does not foam excessively, care should be taken to prevent excessive aeration of the treated fluids.
