Brine viscosities are an important property in sand control and coil tubing operations. Viscosities are used to calculate sand settling rates for gravel packing and frictional pressure losses. Due to limited brine viscosity data, viscosites were determined for conventional completion fluids using an Oswald viscometer. Then three dimension equations were determined as a function of density and temperature for calcium chloride, calcium bromide, calcium chloride and calcium bromide, calcium bromide and zinc bromide, three salt mixture of calcium chloride, calcium bromide and zinc bromide, and sodium bromide solutions. All equations had an average deviation from the measured values of less than 10%.
