Abstract

An oil well capsule (10) to reduce the paraffin, asphaltene, and hydrates which accumulate on the walls of the pipes which are used to bring the oil up from underground deposits, and a method of using said oil well capsule (10). An oil well capsule (10) having a shell (14) encapsulating a chemically active mass (12) wherein said chemically active mass (12) consists essentially of alkaline or alkaline earth metal. An oil well capsule in the shape of a toroidal cylinder (30) containing the chemically active mass (12). An oil well capsule (10) with the shell pierced by a plurality of perforations (40) to increase the initial contact surface.
