IntelliZone Compact II

Modular multizonal management system

First installation

Simplify intelligent control with an economical, integrated flow control system

Integrate production modeling, completion, and remote operations with the IntelliZone Compact II modular multizonal management system of components for , an engineered 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.

Minimize installation rig time with preassembly and pretesting

The downhole system integrates an on-off or four-position 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.

Reduce deployment complexity with multidrop capability

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.

Simplify valve control with two computer clicks

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.

Improve performance as 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.

Manage your reservoir with digital data delivery.
Our permanent downhole gauges let you monitor your wells and reservoirs in real time and identify trends that can optimize well productivity and hydrocarbon recovery—without costly, time-consuming well interventions.
