Abstract:

A pressure relief system configured to automatically monitor and correct overpressure events in hydraulic fracturing or well stimulation activities is disclosed. The system generally includes at least two valve assemblies each having a valve and a valve actuation system, at least one pressure sensor, and an electro-mechanical control package. These components are configured such that the electro-mechanical controls automate the open and closed positions of the valve(s) via operation of the actuator(s) based on information from the pressure sensor. This architecture allows the system to monitor and interpret pressures within the conduit and operate the valve position based on user defined set-points. The valves may be positioned to redundantly monitor the same fluid conduit, or separate fluid conduits, and the system may be configured to enable independent valve positions based on independent user defined set-points or user inputted control signals.
