Abstract
What is claimed is a downhole lubrication system comprising a drill string component comprising an outer diameter and an inner bore. A reservoir may be disposed intermediate the outer diameter and inner bore. A piston may be disposed at least partially within the reservoir. At least one channel may extend from the reservoir to a bearing surface. As drilling fluid is passed through the inner bore, the piston may be pressurized, urging lubricant toward the bearing surface via the at least one channel.
