IntelliZone Compact II Modular Multizonal Management System

Flow control technology for multizone wells

IntelliZone Compact II modular multizonal management system is a fully integrated monitoring and flow control technology for multizone wells. It brings together as one compact unit an advanced design and production modeling engine, a fully integrated completion module, and a user-friendly remote operating system.

Preassembly and pretesting minimize installation rig time

The downhole system integrates the on-off or four-position TRFC-IZ flow control valve, valve position sensor, ESP-noise-immune pressure and temperature gauges, packer, and optional multidrop module in one compact unit. The system is assembled and tested at manufacturing and delivered as a single, integrated unit ready to install out of the box, minimizing field connections and saving rig time compared with conventional intelligent completions.

Multidrop capability reduces deployment complexity

The system’s integrated design helps reduce the number of hydraulic lines required without reducing the number of valves the operator can control downhole. The multidrop capability simplifies the wellhead interface and eliminates the requirement for custom wellheads.

Two-click computer control simplifies valve control

With control logic programmed into the surface control system, valve operation is a simple two-click computer command. Unlike sliding sleeves, no rig-based intervention is required to modify valve position.

System provides multiple advantages compared with concentric dual completions

A concentric dual completion is a conventional method of producing two zones simultaneously and independently, but the IntelliZone Compact II system has several advantages.
