The oil and gas production organizations have used the service factors applied to sucker rod string allowable loads and stresses for many years. However, many have used the service factor described in API RP 11BR1 only to reduce the maximum allowable stress since they are operating in corrosive service. This paper will discuss the development of the service factors and provide recommendations not limiting the rod loading by using a derating factor.
