Artificial lift system for stripper and marginal wells

A method for the removal of fluid from a well comprising:

• employing an upper extraction unit comprising a lifting mechanism to lift and lower an extraction container into the well, wherein the extraction container comprises a top, a bottom, an open configuration, a closed configuration, a valve assembly and a linear gear;
• lowering the extraction container into the well;
• lifting the extraction container from the well;
• draining the fluid from the extraction container onto a drainage tray;
• diverting the fluid from the drainage tray into a collection tank;
• and
• repeating the step of lowering the extraction container into the well.

A continuous method for the removal of fluid from a well comprising:

• lowering an extraction container having a top;
• a bottom;
• an open configuration;
• a closed configuration;
• flexible metal hose;
• a valve assembly comprising a fluid retention valve, at least one valve blade, a valve connecting rod, a rod tension spring, a rod guide, and a rod stop;
• and a linear gear into the well;
• employing an upper extraction unit to lift and lower the extraction container from the well,
• lifting the closed configuration extraction container from the well while simultaneously contacting the linear gear of the extraction container with a curvilinear gear movably located on the upper extraction unit, wherein the curvilinear gear is engaged to a drainage tray that is movably rotated into a position under the extraction container;
• continuing to lift the extraction container from the well while simultaneously contacting the valve assembly located on the extraction container with a travel stop means located on the upper extraction unit;
• wherein the extraction container is in the open configuration;
• draining the fluid from the open configuration extraction container onto the drainage tray;
• diverting the fluid from the drainage tray into a collection tank;
• and
• lowering the extraction container into the well, wherein the linear gear contacts the curvilinear gear movably rotating the drainage tray away from the extraction container and wherein the extraction container is in the closed configuration as the valve assembly loses contact with the travel stop means.

A continuous fluid extraction system for the removal of fluid from a well, the system comprising:

• an extraction container comprising a top, a bottom, flexible metal hose, an open configuration and a closed configuration, wherein the extraction container defines an inner volume capable of storing fluid;
• an upper extraction unit comprising a lifting mechanism movably connected to the extraction container, support means and travel stop means, wherein the lifting mechanism is capable of lowering the extraction container into and lifting the extraction container out of the well;
• a valve assembly comprising a fluid retention valve, at least one valve blade, a valve connecting rod, a rod tension spring, a rod guide, and a rod stop, engaged to the extraction container, wherein the extraction container is in the open configuration when the valve assembly is contacted by the travel stop means as the extraction container is lifted out of the well and wherein the extraction container is in the closed configuration when the travel stop means is not in contact with the valve assembly as the extraction container is lowered into the well;
• a drainage tray movably engaged to the upper extraction unit;
• a curvilinear gear engaged to the upper extraction unit and the drainage tray;
• and
• a linear gear engaged to the extraction container, wherein as the extraction container is lifted out of the well the drainage tray is moved to a position under the extraction container when the curvilinear gear is contacted by the linear gear and when the extraction container is in the open configuration the drainage tray is in the position under the extraction container ready to divert fluid expelled from the open configuration extraction container into a collection tank.
