SGA® - Self-diverting Gelled Acid

Typical Properties and Field Applications

SGA technology was commercialized in 2016 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 60-300℉ (15-149℃)
Formation:    
Carbonates with variation in petro-physical properties
Treatment fluids:   
HCl, self-diverting acids
Mix-water:      
 Fresh water

Further information about field applications is described in documented “Case History of SGA Technology”.

Typical rheological and physical properties of SGA fluids are shown in the following Figure and Pictures.


                            


Precautions and HSE Considerations

Acid gelling agent (KMA027G), SGA crosslinker (KMA024) and SGA iron control agent (KMA022B) in SGA systems play the most important roles in treatment effectiveness. In addition, corrosion inhibitor (KMA034C) and inhibitor aid (KMA030 and KMA031) are generally used in SGA systems to protect the tubing from corrosion. H2S scavenger (KMA009) and H2S scavenger Aid (KMA009B) are compatible with other system additives.

The laboratory procedures, quality assurance program and guidelines for field mixing and handling of SGA systems are described in SGA fluid manual.
