Abstract
This invention relates to sealing small leaks in oil containers such as tankers, underground storage tanks, and the like, by plugging the orifice of the leak utilizing water-soluble polymers which have been dispersed in a water-in-oil emulsion wherein the oil is the continuous phase. The active sealant consists of small densely packed spheres of the water-soluble polymers which have an effective size of about 0.5-500 microns. The dosage on an oil-wet surface is about 3-15 percent based on the weight of the oil present and may alternatively be measured as about 10-1000 ppm of polymer spheres applied to the orifice.
