Turn the reservoir into selective producing zones for better control
Challenge
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.
Solution
Saltel Industries Annular Zonal Isolation Packers (AZIP) simulate combined effects of temperature drop and differential pressure. Metallic and elastomeric material selection adapted to the well conditions allow for multiple acid treatments during the life of the well.
