Potential sources and sinks of methane (CH 4) on Mars

Potential sources and sinks of methane (CH4) on Mars.

A safety valve system for removing down-hole tools from a coal-bed methane well.

Vertical slots cut in methane well risers allow methane gas, LFG derived from the decomposition of waste, to enter the existing riser and extraction system.

The dewatering system with the submersible pump is used to pump water from vertical coal bed methane wells.

In some embodiments, the invention may be the redistribution of water produced in a coal bed methane well.

The quantity of nitrous oxide produced by natural sources is completely offset by natural sinks and has been for thousands of years.

Enzymes and stimulants identified by invention methods can be used in processes for enhancing biogenic methane production, for example, by addition to coal seams and coalbed methane wells.

Because of this anisotropic permeability, drainage areas around coal bed methane wells are often elliptical in shape.

In Australia up to 40% of coal bed methane wells are hydraulically fractured to increase the flow of water and gas.

In Australia 10-40% of coal bed methane wells are hydraulically fractured to increase the flow of water and gas.
