... connection make up variables, how those variables could affect operational reliability, and how to achieve optimal make up conditions. The variables considered were connections with and without pin lube, various coupling and rod grades, and sucker rod tong capabilities. This study was performed using...

... Abstract The sucker rod joint is designed to be made up to a given preload stress level in order to prevent separation between the pin shoulder and the coupling face during operation. As long as the connection is correctly made up, non-failures are expected to occur working within the fatigue...

... Abstract This paper presents a feasibility assessment of eliminating the protector of an electric submersible pump (ESP) by transferring the torque from the motor to the pump using a magnetic coupling, thereby allowing the motor to be hermetically sealed from the wellbore fluids...

..., using upsets of smaller diameter (e.g. slimhole couplings instead of full size couplings) will reduce the effective curvature. Either of these will have a significant effect on the fatigue life. Fatigue Test Method Considerations There is currently no standard test in the industry for testing...
