Annular casing packer
The Annulus Casing Packer (ACP) is an inflatable packer assembly designed to be installed as part of a casing string or liner and inflated in either cased or open-hole sections of the well. It’s primary function is to Prevent gas migration, reduce the gas-to-oil production ratio, reduce or prevent water production. Isolate production or injection zones.
Once inflated, the ACP creates a reliable, impermeable annular barrier, helping to isolate zones and maintain well integrity.
The tool is suitable for vertical, highly deviated, and horizontal wells, making it a versatile solution for a wide range of well completion and zonal isolation applications.
