Frac Protection System

Protect personnel and surrounding area from pressurized fluid

Designed to protect against over-pressure events during fracing operations, the NOV Frac Protection System (FPS) protects personnel and the surrounding area from the pressurized fluid by relieving fracturing fluid into a tank.

The standard FPS skid includes a manifold section, relief tank, hydraulic power unit, and control system. This unique system is available in multiple configurations—with and without a 72-bbl flowbank tank and reduced functionality to decrease on-site footprint.

During fracing operations, the FPS is connected to the primary treatment line, and a signal from the FPS skid control system or the customer’s data van will trigger the relief valve in case of over-pressurization in the line.

Our relief valve will open the instant an over-pressure event has occurred, and up to three pressure transducers will be monitoring working pressure every 20 milliseconds upstream from the FPS. The controls system will email a report every time an over-pressure event occurs, and over-pressure relief points can be set locally or remotely while the FPS is in service.

Versatile design, allowing fit-for-purpose utilization

• Tankless FPS: With the 72-bbl storage tank removed, this option reduces the footprint by approximately 45% while still maintaining all the benefits from the full-sized FPS. Discharge from the FPS can be routed to a discharge tank via a 3-in. 1502 connection on the FPS. 
• Compact FPS: In this design, the 72-bbl tank and the main treatment and test isolation valves have been removed while still retaining the redundancy of the two relief valves installed in series. This option offers a 55% reduction in footprint compared to the full system while maintaining the FPS’s core functionality, ensuring reliable and repeatable operations.
