Shooting 



In certain cases if acidization of a well does not increase production, 

 shooting is initiated. Some operators do not favor this procedure be- 

 cause of the possibility of the many major problems which may arise as a 

 result. Other operators recognize the procedure as routine. Actual ex- 

 amples have occurred where a reduction in production resulted from 

 shooting.
