Abstract
A downhole system and method for producing and unloading from a well unloads a first fluid through a tubular in the well while blocking flow of a second fluid into the tubular. In an alternate mode, the second fluid is produced through the tubular while the first fluid is blocked from entering the tubular. In another alternate mode, a third fluid is unloaded through the tubular at the same the second fluid is produced from the well and through the tubular. In yet another alternate mode, the second fluid is pressurized downhole. In one example, the first fluid includes water, the second fluid includes a hydrocarbon gas, and the third fluid includes a hydrocarbon liquid. Means for unloading include a pump, means for pressurizing the second fluid include a compressor, and means for selectively blocking flow includes a flow circuit with one-way valves.
