SafeInject™ Chemical Injection System

With a focus on efficiency and safety, Cactus Wellhead™ has developed the Cactus™ SafeInject™ system which allows the user to grease valves on frac trees and manifolds while keeping personnel out of the hazardous zone.

BENEFITS

• Grease manifold skids are located close to the frac trees. This allows for the use of shorter grease hoses which results in improved grease flow to the valve.
• A grease supply skid is located in the hazardous zone and connected to the grease manifold skids through the use of large diameter trunk lines to improve grease flow.
• The HMI control skid is located outside of the hazardous zone and allows the user to manage the greasing of all of the frac tree and manifold valves that are connected to the system.
• The HMI allows the user to define the frac trees by name and color with a graphical display of the customer’s frac tree. The HMI touch screen allows the user to select the valve that needs to be greased, as well as a manual or automated greasing process. It can also provide an overview of the greasing status of all of the valves.
• Valves on idle wells can be greased while frac activities continue on other wells thus reducing, or even eliminating, NPT associated with greasing. Customers have reported improvements of up to 2 stages per day while using the SafeInject™ system.
• A grease meter is used to log the amount of grease that is pumped to each of the valves. This allows for a more accurate indication of the amount of grease that is pumped when compared to the standard practice of counting pump strokes.
• Valves using the SafeInject™ system are equipped with Cactus™ large bore grease fittings, which further help to improve grease flow.
