Paper: Sucker Rod Design-Steel Mill to Oil Well

After consideration of all component parts in a sucker rod pumping installation, it is believed that the sucker rod string most directly affects the action and performance of the entire system. Sucker rod behavior, in transferring the forces and loads that are involved, determines the action of the subsurface pump. The load imposed on the surface equipment are attributed directly to the inherent characteristics of the sucker rods. The allowable stresses , range of loads imposed and speed of operation, which a sucker rod string can withstand without excessively frequent breakage, limit the economic depth and capacity of an installation.
