Install IntelliZone Compact system
To meet the original design criterion of using the existing wellhead
equipment, Schlumberger recommended its IntelliZone Compact modular zonal
management system. This system integrates a flow control valve, an optional
pressure and temperature monitoring system with valve position sensing, an
optional multidrop module, and a packer. The optional multidrop module allows
more flow control valves to be actuated on fewer hydraulic control lines than
with traditional flow control completions and to be controlled from the surface
in real time without intervention.
The Schlumberger IntelliZone Compact systems were deployed, each with
one cased-hole packer and two swellable packers. By using these systems, the
operator was able to selectively control all three zones with a single
Control line pressure applied at the surface actuated the appropriate
valves necessary to perform the acid treatment selectively. Treating the
specific zones individually allowed for optimal stimulationwithout the
need for a rig or coiled-tubing intervention.
