Abstract
A method of well rehabilitation using CO2 comprises a more effective distribution of effective CO2 energy throughout an entire well structure including all parts of a producing interval of a well and surrounding formation. The CO2 phase changes are controlled during CO2 injection to cause surging agitation within a well bore and surrounding formation and allow CO2 energy to reach all areas of the well, and the CO2 energy utilized includes at least one of chemical energy, thermal energy and mechanical energy.
Claims17
In a method of well rehabilitation using CO2, the improvement comprising providing a more effective distribution of effective CO2 energy throughout an entire well structure including all parts of a producing interval of a well and surrounding formation, and distributing CO2 energy throughout the entire well structure by controlling CO2 phase changes during CO2 injection to cause surging agitation within a well bore and surrounding formation and allowing CO2 energy to reach all areas of the well, wherein the CO2 energy utilized is at least one of chemical energy, thermal energy and mechanical energy.
An improved system for well rehabilitation, the improvement comprising a volume displacement pipe adapted to be inserted into a well prior to CO2 injection, wherein the volume displacement pipe has a smaller diameter than a well screen or borehole wall, and the volume displacement pipe is adapted to require less energy to displace water in the well and to direct a combination of cleaning energies more effectively to the screen or fractures of a rock well, and an energy injection port wherein the energy injection port has at a distal end an energy diversion port.
The improved system of cairn 14, wherein the energy diversion port can be an energy quick release valve.
