Stimulation/Production Chemicals

15% hydrochloric acid, field mixture.                                                                                     

Product Data Sheet

31.5% hydrochloric acid, concentrate.    

5% intensified hydrochloric acid, field mixture.  

3% weak hydrochloric acid, field mixture.        

12% HCl-3% HF acid field mixture for removal of damaging clay and silt minerals. A standard mud acid formulation.

12% HCl-6% HF acid field mixture for rapid removal of damaging clay and silt minerals. A derivative of the 12/3 mud acid.  

Granular acid salt used to prepare A-20 and A-21. Added to the premixed HCL solution at concentrations ranging from 400 toÞ 800 lbs A-29 per 1000 gal of acid. Necessary component for HF acid solutions.

Retarded acid blend, acetic/hydrochloric. For use in slowing acid reaction rates in high temperature wells.

Alcohol/acetic acid blend for retarded activity and rapid cleanup.  

Concentrated acetic acid. High temperature applications. Þ Reacts slowly when compared to HCl in carbonate formations. Used to prepare field strength acid solutions, typically 10 to 11%.                                                                                                                                                                                          

Concentrated formic acid. Used to prepare field strength concentrations of approximately 9% acid. High temperature applications. Reacts slowly when compared to HCl.      

Specialty acid mixture used to dissolve damaging clay minerals and consolidate and stabilize the formation matrix. Typically supplied at about 50% active strength, and is used as a concentrated source of HF acid.  

Oil miscible acids can be prepared for HCl systems up to 28% acid concentration. Using a combination of surfactant oil-wetting and emulsion retardation, the acid reaction rate for 28% HCl can be retarded approximately fifteen-fold. At lower acid strength, even greater amounts of retardation are achieved. (See "OMA " section).                                                                                          

Organic acid mixture for use in acid sensitive formations and for mud/scale removal.
