Definitions for "Acid stimulation"
Form of hydrochloric acid is pumped down well hole to enlarge pore space in oil bearing rocks to increase flow and recovery.
Acidizing of a well. Process of introducing acid into a well to dissolve acid soluble materials, in the wellbore or in reservoir rock near the wellbore, which might be restricting fluid flow. Acid-soluble materials in the reservoir rock might occur naturally or might have been introduced during the drilling or completion process of the well. Commonly used acids are hydrochloric and mixtures of hydrochloric and hydrofluoric; although other mineral acids and organic acids have been used, notably citric acid and acetic acid.
The stimulation of an unoperational reservoir in a formation using a reactive acidic fluid
