Systems and methods for providing notifications to monitoring systems that are remotely located from a well upon failure of a surge suppressor in a drive system for equipment used in the operation of the well. In one embodiment, an ESP system is installed in a well. A VSD having a surge suppressor is coupled between a power source and the ESP system. The surge suppressor is monitored to detect a failure of its surge suppression capabilities. In response to detecting a failure, a notification is provided to a monitoring system that is located remotely from the well. The notifications may be provided via phone call, email, text message or other means. The surge suppressor may also provide a local indication of the failure. The VSD may be configured to continue operation despite the failure of the surge suppression capability.

Systems and methods for detecting and communicating failure of integral surge suppression in drive systems for downhole equipment

A subsurface safety valve has a closure sleeve or rod mounted below the closure mechanism. Control signal pushes the sleeve up (uphole) or down (downhole), whichever is applicable, which causes the closure element to rotate (or slide, or otherwise translate) to its open position. A loss of control signal allows the closure spring to push the sleeve or rod downhole (or uphole, whichever is appropriate). This movement causes the closure element to be driven to its closed position against the seat.
