Annulus Casing Packer (ACP)
The Annulus Casing Packer (ACP) is an advanced downhole sealing solution providing reliable annular isolation between casing strings and wellbore formations, playing a critical role in maintaining well integrity, controlling pressure zones and improving drilling and production efficiency. Manufactured using advanced elastomer materials and precision engineering, the ACP is an inflatable packer assembly installed as part of a casing string or liner and inflated in cased or open-hole sections — its primary function is to prevent gas migration, reduce gas-to-oil production ratio, reduce or prevent water production, and isolate production or injection zones.
We are the India local partner for Star Petrotech Pte. Ltd, Singapore, manufacturer of downhole completion tools.
