ABSTRACT:
The present invention relates to a method of removing deposits from various types of wells (17) including environmental recovery, water supply, horizontal, barrier, injection, recharge, and/or disposal wells (17). The method includes equipping a well (17) with an automated energy delivering system that is attached to the well (17). The energy delivering system is used to clean the surface of the well (17) and aquifer by supplying various types of energy to the well (17) and aquifer via injection lines (5, 6, 8, 11and12) and an educator pipe (10). A pump (14) is used to pump the energy through flow valves (21and20) and injection lines (5, 6, 8, 11and12) and into the well (17). The energy that is supplied to the well (17) mobilizes any deposits in the well (17) and aquifer and cause them to flow into and up the wellbore thereby cleaning the well (17) and aquifer.
