Typical Properties and Field Applications
CAT technology was commercialized in 2013 successfully and has been applied in various oil and gas fields in the world. It has been proved to be effective in treatment of carbonate reservoirs with the following conditions:
|
Temperature: |
BHST 60‑350°F (15‑177°C) |
|
Formation: |
Carbonates with variation in petro-physical properties |
|
Treatment fluids: |
HCl, organic acids, self-diverting fluids. |
|
Mix-water: |
Fresh water, sea water or brines |
Precautions and HSE Considerations
Viscoelastic acid diverter (KMA007, KMA007A and KMA007B) in CAT systems play the most important roles in carbonate treatment effectiveness. In addition, corrosion inhibitor (KMA034A) and inhibitor aid (KMA030 and KMA031) is generally used in CAT systems to protect the tubing from corrosion. The iron reducing agent (KMA003) and iron stabilizer (KMA003BL and KMA033) are generally used in CAT systems to prevent the iron precipitation in the formation. H2S scavenger (KMA009) and H2S scavenger Aid (KMA009B) are compatible with other additives in CAT systems.
The laboratory procedures, quality assurance program and guidelines for field mixing and handling of CAT systems are described in CAT fluid manual.
