Method for stimulation of liquid flow in a well

摘要

An improved method of controlled energy delivery utilizing solid, liquid, and gaseous carbon dioxide (CO₂) into a water well and the surrounding aquifer to remove deposited material which may cause loss of capacity in wells and a variety of water quality problems. After proper study and evaluation of problems associated with a well to be treated, adequate injection of the required amount of CO₂ and energy is achieved by real-time monitoring during the injection and manipulating the phase changes in the CO₂ that take place in the well and the aquifer.
