The success of the sucker-rod system for pumping oil wells is due, primarily, to the pumping oil wells is due, primarily, to the simplicity of the surface, as well as the subsurface equipment. In the early life of the industry the wells were shallow and could be adequately pumped with beam-type surface equipment. As wells were drilled to greater depths
