Processes and systems for treating oil and gas wells

A tool capable of being spooled into a fluid layer through a production tubing without disturbing the production tubing for removing fluid from a subterranean well to allow enhanced hydrocarbon production through a production string comprising:

• a container positioned in a subterranean well;
• a gas injection conduit, independent from the production string, in fluid communication with the container for providing a fluid path for injecting an injection gas from an earth surface proximate location into the container;
• a fluid return conduit, independent from the production string, in fluid communication with the container for providing a fluid path for transferring at least one subterranean fluid from the container to an earth surface proximate location;
• a gas injection valve that defines an interface between the gas injection conduit and the container;
• a relief valve that defines an interface between the subterranean well and the container;
• a return valve that defines an interface between the fluid return conduit and the container;
• and,
• a container valve that defines an interface between the subterranean well and the container;
• wherein the relief valve is positioned on the system at subterranean depth above the container valve, wherein the gas injection conduit and the fluid return conduit are within the tool, and
• further comprising a gas injection valve orientation, wherein the gas injection valve and the return valve are closed, and the relief valve and container valve are open, resulting in fluid entering the return conduit;
• and, a second valve orientation, wherein the gas injection valve and the return valve are open, and the relief valve and container valve are closed;
• and wherein the second valve orientation pressurizes the container.
