Methane hydrate will most likely be produced first from deposits where the following conditions are met: 1) the hydrate occurs in high concentrations; 2) it occurs in a high-permeability host rock that has good reservoir quality; and 3) the deposit is located in an area with existing infrastructure. |

Methane hydrate is a fairly concentrated form of natural gas. When dissociated at normal surface temperature and pressure, one cubic foot of solid methane hydrate will release about 164 cubic feet of methane gas. This is one of the reasons people are interested in methane hydrate as a potential source of methane for energy supply. |

Most natural gas is produced from conventional gas accumulations by drilling a well into the reservoir rock, casing the well with pipe, perforating the pipe to allow the gas to flow into the wellbore, placing a string of tubing inside the casing, and then extracting the gas up the tubing, sometimes with the aid of a pumping system. In some cases, natural gas flows freely up the tubing without the aid of a pumping system, because of high pressure in the reservoir. |
