Abstract
Well damage, in the form of various impediments to fluid flow through the formation rock, can reduce or completely eliminate production or injection rates of the well. Prevention and/or removal of well damage have consequently become a major field of study and concentration within the petroleum industry. Although acid solutions have been used for well-damage removal since before the turn of the century, there are situations in which acid is not the best choice for damage removal. The most obvious condition under which acid is not applicable is where the damaging mechanism is not appreciably soluble in acid solutions. Use of acid here would be a waste of time and material.
