Energy Resource Potential of Methane Hydrate


Quiz Questions

1. Natural gas is a relatively clean-burning energy fuel with a wide variety of end-uses.
True
False
2. The worldwide volume of methane held in methane hydrate is immense and poorly known. Estimates range from 100,000 to more than 1,000,000 Tcf of natural gas.
True
False
3. 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.
True
False
4. Methane hydrate does not occurs in either terrestrial nor marine environments.
True
False
5. A __________________ is a chemical compound in which molecules of one material form a solid lattice that encloses molecules of another material.
Clathrate
Crystal
6. Methane, made of one carbon atom and four hydrogen atoms, is the simplest hydrocarbon molecule and the primary component of natural gas.
True
False
7. 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.
True
False
8. ______________________ is produced by the combined action of heat and pressure over a long period of time on buried organic material.
Methane Hydrate
Thermogenic methane
9. The DOE program mission is to advance the scientific understanding of naturally-occurring methane hydrate, such that its resource potential can be fully understood and realized.
True
False
10. 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.
True
False
