Don’t worry, just a little bump - $70 is just around the corner. Short traders just keep making those margin calls, mortgage the house if you have to. Fortunes await you! PO is for pansies and doomers. At $70 short some more ..... it is going back to $22 .... the world is awash with oil ........ reality has nothing to do with it, its all in those charts!!!!!!!!!!

The mining technique reminds me of SAG-D used to recover bitumen. But instead of Bitumen you get gas. Presumably the heat required to melt the clathrate is less than the heat energy of the methane released, but it doesn't sound like any sort of near term resource.
However, it is certainly NOT going to help the urgent issue. If the clathrates are stably emprisoned in a hydrate shell, they are not contributing to the carbon cycle, therefore they are not making an additional loading of either CO2 or, worse, CH4 to the atmosphere.
If, by some miracle, they could be exploited economically, they will cause an additional loading of both. This is something we do not need. In reality, this is something we should avoid at all costs.

Although hydrate extraction is still in the "decades away" and "at least 6x current costs" realm, I thought, "hey, if we can lower costs and improve collection at a rate similar to the tar sands, maybe we can get it working. It would be a global warming nightmare, sure, but it would solve the gas problem." The two tasks seem comparable.
However, ASPO's own Jean Laherrere has debunked Methane Hydrates. To paraphrase, they are "far too spread out to ever be conceivably economical" and "only useful perhaps as an alternative storage technique to LNG for transportation."
From dieoff.org's synopsis page:
Quote:
OCEANIC HYDRATES
Laherrere has provided two papers that show there is no evidence from all the worldwide research and extensive coring for any massive hydrate deposits. http://dieoff.com/page192.htm -- http://dieoff.com/page225.htm . According to Fleay:
Gas hydrates resources on the ocean floor are formed at depth where the pressure is high enough and the temperature low enough which means the hydrates are DISPERSED and not amenable to processes to concentrate them in large reservoirs as happens with natural gas and oil. For this reason the cost of extracting them would be formidable and would certainly end up being an energy SINK not a source. Jean Laherrere is well informed on this having been involved in exploring for ocean floor gas hydrates.
