i-Opener OH Toe Initiation Valve

The i-Opener openhole (OH) is a toe initiation valve with a cyclic activation mechanism that allows the casing string to be pressure-tested multiple times before it initiates flow to the formation.

  • Resources Resources

This innovation makes pressure testing the casing independent of the activation of the opening sleeve. It allows three casing pressure cycles before initiation of flow.

i-Opener™ can be installed as part of a cemented or openhole completion and can be made up to any casing thread type.


  • Toe valve with a cyclic casing pressure testing mechanism
  • Allows three pressure test cycles before establishing a flow rate
  • Fully compatible with either cemented- or openhole-type completions
  • Manufactured to match casing size, weight, material, and connection type
  • Design suitable for high-temperature and high-pressure applications


  • Decouples casing pressure test from flow initiation operation
  • Eliminates costly intervention for activation or re-establishment of flow
  • Provides numerous pressure test attempts
  • Can be run as part of a variety of multistage fracturing systems
  • A sliding sleeve exposes all nozzles to the formation at once
  • Large flow area nozzles for increased pumping efficiency and the ability to perform a toe-stage frac


  • Cemented or openhole completions
  • Wells in jurisdictions requiring casing integrity tests
  • Wells in which flow initiation pressure cannot exceed test pressure
