ESTMZ™ Enhanced Single-Trip Multizone Completion System


Designed for use in deepwater and ultra-deepwater offshore completions, the ESTMZ™ system enables several intervals within a well to be isolated and treated with a high-rate frac pack during a single trip of the workstring.


  • Full 10,000 psi differential pressure rating
  • Highest rated frac and proppant rating in the industry
  • Largest system ID in the industry
  • Modular screen provides formation isolation
  • Capture short, low reserve intervals that would normally be bypassed
  • Accommodates SmartWell® system completions

The Deepwater Completion Solution Example
Halliburton's ESTMZ™ system has the potential to save up to 42 days of rig time on a five zone (1,400 foot producing interval) Lower Tertiary completion.  Based on a $1 MM spread rate that is a $42 MM savings!
