ESTMZ™ enhanced single-trip multizone system

Revolutionizing deepwater completions for maximum efficiency

The ESTMZ™ enhanced single-trip multizone system is designed for deepwater and ultra-deepwater completions. It enables isolation, fracture stimulation, and treatment of multiple production zones,—all in a single trip. By doing so, it significantly reduces rig time and delivers substantial cost savings compared to traditional stack-pack completions.

Building upon the success of the STMZ™ single-trip multizone system, the ESTMZ system offers additional features for today’s demanding deepwater environments. These enhancements not only minimize overall completion costs but also maximize well productivity by significantly reducing the number of rig days required for frac-pack multizone completions.

Applications

Multizone cased-hole and open-hole installations
Deepwater and ultra-deepwater completions
Mature fields
Developing fields

Features

Available in 9 5/8 and 7-in. cased-hole and 8 1/2-in. open-hole system sizes
Single workstring trip to deploy
Full 10,000-psi differential pressure rating with barrel slip packers
Up to 45 bbl/min stimulation rate with a cumulative 3,750,000 pounds of proppant

Benefits

Reduces the number of workstring trips, which helps lower overall completion costs
Helps minimize risk by allowing perforation of all zones simultaneously and removing temporary packer plugs from the operation
Increases the operating envelope for deeper wells and allows fracturing design optimization
