ABSTRACT:
A method of well treatment designed to enhance recovery of resources from the well. A solution with an alkaline pH greater than 8 is introduced into the well and allowed to react in the well for at least a minimum period of time. A neutral solution with a pH near 7 is introduced into the well and allowed to remain in the well for at least a minimum period of time. Finally, a solution with an acidic pH of approximately 1 is introduced into the well and allowed to react in the well for at least a minimum period of time.
