Reduce risk, costs, and time

Valves on the frac tree and manifold need regular maintenance (grease injection) during hydraulic fracturing operations. The automated valve greasing system streamlines valve maintenance activities. The system’s remote operating capability eliminates the need for personnel to enter the red zone for valve maintenance and reduces maintenance time by up to 25%. Eliminating transition time and greasing from the critical path means that you save money and achieve first production sooner, with fewer people on location.

The system comprises a remote-control skid that houses a human machine interface (HMI) outside the red zone and a grease injection unit (GIU) that is placed in the red zone. Greasing hoses, which are attached to the GIU, are affixed to each valve during rig-up and remain in place until rig-down.

Deliver optimal grease volume for each valve

When maintenance is required, a technician uses the HMI to select the valve that needs greasing. A high-pressure pump on the unit in the red zone pushes grease to the valve. This minimizes risk of human error as well as HSE exposure. Dual grease pumps on each skid improve performance and reliability.

The optimal volume of grease is determined at the user interface via feedback from instrumentation. Grease consumption decreases by as much as 20%. Because no personnel enter the red zone, normal fracturing operations can continue on other wells, further improving wellsite efficiency.
