Once expanded in the cased hole, the AZIP has been exposed to pressured nitrogen while undergoing temperature and differential pressure cycles without experiencing any leaks. Saltel Engineering team has completed this qualification per all ISO 14310 VO standard criteria.

WORKING PRINCIPLE

Saltel Xpandable Steel Annular Zonal Isolation Packer (AZIP) is a unique, stainless steel expandable packer with a high expansion ratio and high differential pressure capability. The AZIP prevents flow between casings or between the casing and open hole to provide cement assurance, prevent the build-up of annular surface pressure, create compartmentalization within the reservoir or isolation between reservoirs.

The ISO14310 V0 standard places Saltel Xpandable Steel AZIP to the industry’s highest standards guaranteeing a zero-gas leakage. This standard now extends the possibilities for the AZIP in cased hole to most gas-producing well applications.
