Thermodynamic pulse lift oil and gas recovery system

A thermodynamic oil and gas recovery system that simultaneously injects thermodynamically treated fluids into an oil and gas well for uninterrupted production from said well during well maintenance wherein said thermodynamically treated fluids are heated, cooled and/or used for said production and well maintenance that includes:

• a compressing means that includes:
• at least two compression cylinders capable of compressing and pumping
• gasses mixed with contained liquids,
• at least one pump, and
• a power supply,
• a power limit means for setting the volume displacements for each of said cylinders,
• a reservoir containing liquids and natural gas,
• said well,
• an output means capable of injecting gasses compressed in said compressing means into said reservoir as lift gas, at least a portion of which may be recovered natural gas from said reservoir,
• a separating means capable of separating said recovered natural gas and recovered liquids from said reservoir, and
• an input means capable of transferring at least part of said recovered natural gas into said compressing means as input gas with the density of said input gas determined at least in part by the composition, temperature and pressure of said natural gas in said reservoir and the plunging action therein.

A thermodynamic lift gas injection unit that injects thermodynamically treated fluids for recovering oil and gas from a well controlled by wellhead gas pressure that includes:

• a compressor with at least two compression cylinders capable of compressing and pumping gasses mixed with liquids, and a switching device for limiting the volume displacements for each of said cylinders,
• external and internal thermodynamic exchange means for cooling gasses during compression and heating liquids,
• a separating means capable of separating recovered natural gas and recovered liquids,
• an output means capable of injecting intermittent pulses of gasses compressed in said compressor into liquids in a subterranean reservoir as large bubbles of lift gas,
• a lifting means capable of lifting said liquids with said large bubbles of said lift gas,
• a recycling means capable of inputting at least part of said recovered natural gas into said compressor as input gas with the density of said input gas determined at least in part by the composition, temperature and pressure of natural gas in said reservoir and the plunging action therein, and
• an injection means capable of injecting maintenance liquids, which may include said recovered liquids, for well maintenance without interrupting production.

The process of simultaneously injecting thermodynamically treated fluids as lift gas and maintenance fluids for well maintenance into an oil and gas well that includes:

• compressing gas in a compressor capable of pumping liquids and gas,
• injecting at least a portion of said gas compressed in said compressor into a subterranean reservoir as lift gas,
• recovering a mixture of liquids and natural gas from said reservoir,
• separating said mixture,
• storing said liquids and any excess of said natural gas, and repeating the process by compressing said natural gas in said compressor as lift gas for the next injection.
