Latest Patents

One of Jamieson's key patents is focused on "Controlling downhole electrical submersible pump based on sensing rotor position." This patent describes an ESP assembly that includes a motor with a stator, rotor, drive shaft, and an asymmetric magnetic ring mounted to the end of the drive shaft. The motor is powered by a surface power source, with electricity delivered through a power cable inserted into the wellbore. The assembly features a downhole sensor that tracks rotor position by monitoring the rotation of the magnetic ring. This information is transmitted uphole along the power cable, allowing a surface controller to process the data and send control commands back to the motor.
