ABSTRACT:
Natural gas wells in a tight formation area are drilled and completed with piping, the piping being capped with a Christmas tree. The piping is then utilized as a reservoir to collect natural gas from the tight formation over a prolonged time period. Mobile pressure vessel units are employed periodically to recover the collected natural gas, on a schedule designed for maximum economic efficiency. In the preferred embodiment, the reservoir is formed between the inner production tubing and the outer casing tubing, and conduits are connected to direct the natural gas from the production tubing into the reservoir. Liquid/gas separators and dehydrator units are employed on wells as necessary, so that the natural gas stored in the reservoir is ready for transport.
