  • Permanent cable for submersible pumps in oil well applications
    Patent number: 8726980
    Abstract: A technique facilitates the employment of an electric submersible pumping system or other well system downhole into a wellbore. The electric motor system is coupled with a signal carrying cable for conveyance to a desired downhole location in the wellbore. The signal carrying cable is constructed with sufficient strength to solely support the electric motor system during deployment and use in the wellbore without addition of a separate supporting mechanism.
    Type: Grant
