摘要：
Subterranean well formations (12) are acid stimulated using a plurality of jet nozzles (22) located in a spaced relation to the wall of the formation to form an annulus (28) between the nozzles and the formation. An acid-containing, stimulation fluid is pumped under pressure through the nozzles, into the annulus and against the wall of the formation. A gas is pumped into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to impact the wall of the formation.
