[0017]Rates of Methane Extraction

[0018]With an assumed dissolved methane concentration of about 15 cubic feet per barrel at 1,000 meters (a little more than 3,000 feet) below ground level, a water production rate of 500 gallons per minute from one well would provide 257 thousand cubic feet (MCF) of gas per day.

[0019]Production of 20,000 gallons of water per minute from a field of 40 wells would provide about 10.3 million cubic feet (mmcf) of gas per day. A field of 100 wells could produce 25.7 million cubic feet per day. Gas water ratios in excess of 23 cubic feet per barrel are common below 2,000 meters (about 6,700 feet) below ground. Gas production from 100 wells drilled to 2,000 meters and produced at the given water rates would be 39.4 million cubic feet per day.

[0020]Dissolved Methane Resources

[0021]Dissolved methane is present in virtually every basin now known to produce oil and dry gas. A typical example is the Great Valley of California. About 10 trillion cubic feet (TCF) ...

Abstract

One undeveloped alternative fuel is methane dissolved in ground water. Equipment for extracting methane from ground water is readily available. This Application presents a process to produce and use dissolved natural gas in the United States. The process includes the use of production wells, pumps, gas/water separators, compressors, low pressure gathering lines, and water disposal wells. Dissolved methane is present in virtually every basin now known to produce oil and dry gas. The Great Valley of California alone contains undeveloped dissolved methane resources of about 1,200 trillion cubic feet (TCF). Dry gas production in 150 years was about 10 TCF. The first full scale test of the extraction process was completed on Jul. 7-8, 2010 in California. Laboratory analyses of the gas produced showed that it was equal in heat value (about 940 to 975 BTU per cubic foot) to dry gas produced from the same field.

NAMES OF PARTIES TO A JOINT RESEARCH AGREEMENT[0001]There are no parties associated with Gary F. Player or any other entity that have a joint research agreement with Gary F. Player.INCORPORATION BY REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISC[0002]No sequence listings, tables, or computer programs have been submitted on compact discs. There are zero (0) compact discs submitted with this Patent Application.BACKGROUND OF THE INVENTION[0003]1. Technical Field[0004]Natural gas production from porous and permeable sedimentary rocks.[0005]2. Background Art[0006]Natural gas prices are subject to market spikes far beyond the control of the largest company or agency. Energy costs in the United States can be freed from the demands of the world petroleum marketplace. One undeveloped replacement fuel is methane dissolved in ground water. This gas is present throughout the sedimentary basins of the world, just a few hundred meters below the surface of the ground. Dissolved methane resources...
