Profrac Toe Initiation Port

Applications
  • Multistage fracturing zonal isolation
  • Stimulation for casing integrity issues
  • Un-cemented horizontal, deviated, and vertical wells
  • Suitable for sandstone, carbonate, and shale plays
Features & Benefits
  • Valve ratings to 10,000 psi and 350 degF
  • Opening pressure of 5,500 psi [37.92 MPa]
  • Large ports increase flow area allows for high flow rates
  • Minimal fracturing pump pressure required
  • Simple increase of internal pressure initiates fracturing operations
    No need for mechanical intervention
  • Only one valve per system required, placed above flow-through circulating valve

Profrac hydraulically actuated frac valve is designed as in integral part of an un-cemented multistage stimulation system, providing a means to initiate communication with the reservoir. Run with liner, the toe port is used for selective stage stimulation. Closing the flow-through circulation valve allows communication to be established with the first fracture zone at the toe of the well.

Positioned above the flow-through circulating valve, the frac valve is activated by applying pressure after circulation valve has been closed. Once activation pressure is reached, the sleeve shifts hydraulically, exposing the ports to the formation and establishing communication with the zone.
