Abstract: A tank system for capturing fluids from an oil or gas well. The system comprises a series of tanks adapted to step down the temperature and pressure of well products from a fossil fuel well while removing gas products until the liquid products contain less dissolved gas in a tank than they could contain at ambient temperature and pressure. Therefore, no venting of gas takes place during the separation. An oil-gas separator is provided within the tank system to separate organic products from non-organic products. Gas products may be flared or delivered for further processing.

Abstract: Systems and methods for producing a well using a gas are disclosed herein. A compressed lift gas can be provided to a well to obtain a production stream. The production stream can be separated to obtain the product and a recycle gas stream. The recycle gas stream can be immediately recompressed for use as lift gas, or separated to form a lift gas stream, and a power stream containing natural gasses from the well. The lift gas stream is recycled for use as lift gas, while the power stream can be transported and/or collected for sale, recycled for use as lift gas, or consumed as power for the compressor, based on measurements obtained throughout the system, coupled with practical and economic variables. By supplementing or replacing generated lift gas and/or an external power source with natural gas from the well, the present systems and methods can become self-contained after start-up.
