AN APPARATUS FOR EXTRACTING DISSOLVED METHANE FROM GROUND WATER AQUIFERS

摘要

One undeveloped alternative fuel is methane gas dissolved in ground water.Equipment for extractingmethane from ground water is readily available. This Application presents aprocess to produce anduse dissolved natural gas in Canada. The process includes the use ofproduction wells, pumps,gas/water separators, compressors, low pressure gathering lines, and waterdisposal wells.Dissolved methane is present worldwide in virtually every basin now known toproduce oil and drygas. The Great Valley of California in the USA alone contains undevelopeddissolved methaneresources of about 1,200 trillion cubic feet (TCF). Dry gas production in 150years was about 10 TCF.The first full scale test of the extraction process was completed at the GillRanch Gas Field onJuly 7 - 8, 2010 in California. Laboratory analyses of the gas produced showedthat it was equal in heat value.
