The invention relates to a method of well rehabilitation using CO2. The improvement comprises providing a more effective distribution of effective energy throughout the entire well structure including all parts of the producing interval of the well and surrounding formation and distributing energy throughout the entire well structure. The improved method is obtained by controlling CO2 phase changes during CO2 injection to cause surging agitation within the well bore and surrounding formation and allowing CO2, mechanical energy and optionally chemical energy to reach substantially all area of the well.
In a method of well rehabilitation using CO2 the improvement comprising providing a more effective distribution of effective energy throughout an entire well structure including all parts of the producing interval of the well and surrounding formation and distributing energy throughout the entire well structure by controlling CO2 phase changes during CO2 injection to cause surging agitation within the well bore and surrounding formation and allowing CO2, mechanical energy and optionally chemical energy to reach substantially all area of the well.
An improved system for well rehabilitation the improvement comprising a volume displacement pipe adapted to be inserted into the well prior to carbon dioxide injection wherein the volume displacement pipe has smaller diameter than the well screen or borehole wall, the volume displacement pipe is adapted to allow less energy required to displace water in the well and directing the cleaning combination energies more effectively to the screen or fractures of a rock well and an energy injection port wherein the energy injection port has at the distal end of the energy injection port an energy diversion port.
