abstract
An account is given on an experimental study of the wormholing process in carbonate acidizing with acetic acid. The experimental results from this study confirmed that the optimal injection rate of acetic acid is lower than the optimal rate for hydrochloric acid. It also showed from the castings that the radius of wormholes created by acetic acid at the optimal rate is larger than that created by hydrochloric acid at the optimal rate. Finally, it is demonstrated how these results can be used to determine the optimal acid system and injection schedule for field application.
