PC Duracaps CI

Conventional down hole treatments for corrosion (i.e. periodic batch treatments) typically introduce large amounts of inhibitor into the service environment to effect a change in the corrosion profile of the well.  These treatments are designed to quickly establish an inhibitor film along the production string and reduce the corrosion level.  The inhibitor film remains on the tubing until it is "stripped off' by incoming fluids.  Depending on the type of inhibitor, production volumes and down hole dynamics, a batch treatment can provide several days on up to a week of protection until retreatment is required.


Although this treating method has been utilized for years, it is known to have undesirable side effects, either at the intended target area or downstream of the target area. Some of the drawbacks include; significant loss of active product due to non-absorption on the production string, formation damage resulting from incidental introduction of foreign fluids into the production zone, and downstream system upsets due to high feedback concentrations of inhibitor immediately after application.


Duracaps Corrosion Inhibitor is designed to offset problems associated with conventional batch treatments by providing long-term, controlled release of inhibitor into the target area at concentrations high enough to maintain corrosion inhibition yet low enough to prevent significant product loss and downstream system upsets.
