India, U.S. Discover Major Natural Gas Reserve in Indian Ocean



  • Find may significantly expand regional energy production
  • Gas locked in hydrate formations may exceed all known supplies

    ” The next step is to determine whether production from the Bay of Bengal site is economic.”

    Let me save you the suspense…the answer is “No.”

    The USGS is a pretty professional bunch, all and all. They sort of screwed things up with shale, but their resource estimates on oil have been pretty good over the years. It is possible that a hydrate deposit in a sand bed could be stable enough to produce. Hydrate is pretty unstable, usually, because it only takes a very small pressure, or temperature differential to release the methane. Drilling rigs supply adequate quantities of both. Ocean oil drillers avoid large hydrate deposits like the plaque. Drilling platforms aren’t cheap.

    Of course, this doesn’t help the real problem – OIL. Replacing our premier transportation fuel is not going to be that easy. India would benefit at least short term. She is a large importer of all the hydrocarbons.

    So did anybody ever figure out how to economically extract methane hydrate, a solid, at the bottom of the ocean? Oh. Nobody figured that out. Back to the drawing board.

    Racer – Economical extraction isn’t even on the table. No one has developed a method for physically extracting a meaningful amount. The Japanese spent over $50 million and didn’t extract enough to beat a single home for more then a few weeks. And haven’t seen an update on those efforts for more then a year.

    The basic problem is that the hydrates aren’t just NG trapped in the reservoir but are actually a physical portion of the structural frame work of the reservoir. IOW if the hydrate is converted to flowing NG a portion of the “rock” itself disappears. Imagine trying to produce NG from a sandstone reservoir when actual portion of the sand is removed in the process.

    Which isn’t difficult for the Rockman because he has seen just that happen. The sand didn’t disappear but flowed up the casing with the NG. With the sand gone the well experienced “point loading” which will quickly causing the casing to collapse and destroy the well.

    So Rock, what percentage of success do you give this new process? Can it be accomplished and be profitable as well,(pun alert).

    I already told you guys how to extract methane that is going to add to the greenhouse effect in the near future. I propose a 50 billion acre tarp, over Siberia, someone call whoever about getting me a grant for this and I will get to work 😉

    Sissy – It’s going to take some a lot smarter then the Rockman to figure out a method. Not sure if folks could understand what I was trying to describe.

    Try this: in a sandstone NG reservoir the gas exists in the lord space between the sand grains. Complete a well and the gas flows thru those pores into the well bore. But in the case of the hydrates those ice crystals (you do understand that much of the hydrate is NG contained in ice crystals?) Essentially by lowering the pressure (or heating the ice) the methane molecules are released from the ice matrix. IOW hydrates are not a solid piece of methane:

    Clathrate hydrates, or gas clathrates, gas hydrates, clathrates, hydrates, etc., are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside “cages” of hydrogen bonded, frozen water molecules. In other words, clathrate hydrates are clathrate compounds in which the host molecule is water and the guest molecule is typically a gas or liquid. Without the support of the trapped molecules, the lattice structure of hydrate clathrates would collapse into conventional ice crystal structure or liquid.

    Sissy – Or to beat that dead horse a bit more bluntly: when the MSM reports huge deposits of frozen methane they are completely full of sh*t and are confusing the public. LOL. The hydrates are huge deposits of ice with a single molecule of methane bound inside a single ice crystal. An ice crystal typically made up of 48 water molecules.

    I just found this general conversion factor from a study evaluating transporting NG as a calthrate instead of as LNG: 100 tonnes of methane = 750 tonnes of calthrate. And thus the problem: for every pound of methane extracted they have to melt/destabilize 7.5 pounds of ice. Ice that makes up the structural component of the “reservoir”.

    Very good to receive the education about drilling. Not practical to drill hydrates. Thanks all. Ya reminds of the Loisiana Lake where they drilled into a salt dome and the lake disappeared. Taking a whole bunch of barges trucks and real estate with it.

    Sick up the hydrate to surface to get Natural gas.

    How deep below the water
