n: a procedure by which acid is forced into a formation under pressure high enough to cause the formation to crack. The acid acts on certain kinds of rocks, usually carbonates, to increase the permeability of the formation. Also called acid fracturing. Compare matrix acidizing.

n: an acidizing treatment using low or no pressure to improve the permeability of a formation with fracturing it. See wellbore soak. Compare fracture acidizing.

acidizing a rock below the fracturing pressure, either to reduce the formation damage or to improve the initial permeability.

n: an acidizing treatment in which the acid is placed in the wellbore and allowed to react by merely soaking. It is a relatively slow process, because very little of the acid actually comes in contact with the formation. Also called wellbore cleanup. See matrix acidizing. Compare acidfracture.
