Reservoir compartmentalization

Reservoir compartmentalization is one of the various existing applications in annulus zonal isolation.

When you need to isolate producing zones for selective EOR purposes, the annulus can be sealed and divided into selective producing areas with annular well packers.

Once installed, they will provide an effective and permanent seal, granting better control of the production area.

The Xpandable AZIP packer (Annular Zonal Isolation Packer) is the robust (expandable steel) alternative to help compartmentalize the annulus in front of the reservoir. The AZIP steel sleeve is expanded between the casing and the borehole by applying pressure in the casing. It conforms to the real wellbore shape. Sealing with the borehole uneven surface is achieved through a patented thin layer of bonded elastomer (associated with expandable dynamic seals for temperatures above 250 degF / 120 degC).
