Apparatus for recovering gaseous hydrocarbons from hydrocarbon-containing solid hydrates

A well apparatus for recovering gaseous hydrocarbons from a formation containing solid gas hydrates, comprising:

• a first conduit means and a second conduit means, each having a bottom end and a top end;
• wherein said first conduit means is located within said second conduit means so as to form a space located between said first conduit means and said second conduit means;
• wherein said first conduit means and said second conduit means each have an open bottom end, and wherein the bottom end of said first conduit means extends to a lower depth than the bottom end of said second conduit means;
• wherein said first conduit means is connected to said second conduit means and is in open communication with space exterior to said apparatus by means of a connector which connects the top end of said first conduit means to a first orifice located along the side of and near the top end of said second conduit means;
• wherein said second conduit means has a second orifice located along the side of and near the top end of said second conduit means, and wherein there is a downwardly projecting sidearm attached to said second orifice:
• and
• wherein said second conduit means is sealable at its top end and at its second orifice.
