ELECTRICAL SUBMERSIBLE PUMP DISSMANTLE AND FAILURE ANALYSIS EVALUATION

A unit that has shut down and does not restart should be analyzed at surface to determine if the problem can be linked to down hole equipment failure or surface condition.

If the down hole unit has failed pulling of the unit should be done with the same care and attention that is given to installation. Valuable information can be collected during the pulling operation that could be used when the equipment is analyzed after pull.
