摘要： A method for deploying a pump system in a wellbore includes coupling the pump system to one end of a tubing encapsulated cable. The cable is extended into a wellbore drilled through a subsurface fluid producing formation. The tubing encapsulated cable has an outer tube extending substantially continuously from the end thereof connected to the pump system to a surface end of the cable. The outer tube is made from material selected to exclude fluid in the wellbore from an interior of the outer tube. The cable includes at least one electrical conductor disposed inside the outer tube, wherein a rated load current of the at least one electrical conductor is selected such that substantially continuous electrical current drawn by the electrical load device exceeds the rated current of the at least one electrical conductor.

摘要： An inline monitoring package for a submersible pumping system includes a housing having a first end for connection to a motor, a pump or a seal section of the pumping system, and a second end for connection to the motor, the pump or the seal section. The housing is disposed between any two of the pump, the motor and the seal section. A shaft transmits rotation from the motor to the pump. The housing comprises a chassis having a through bore and an end plug at each longitudinal end. The through bore has a diameter selected to enable free passage of the shaft and fluid associated with the shaft. The end plugs sealingly engage an interior wall of the housing so as to define a sealed chamber inside the housing and external to the chassis between the end plugs. At least one electronic component is disposed in the sealed chamber.
