摘要： A system for removing methane from subterranean clathrates includes an oxidant source, a feed pipe, a recovery pipe, and an ignition source. The feed pipe includes an inlet end in fluid communication with the oxidant source and an outlet end configured to be disposed within a subterranean deposit that includes a stored methane gas disposed within a clathrate hydrate. The recovery pipe includes a first end disposed within the subterranean deposit and a second end opposite the first end configured to engage a storage device. The ignition source is configured to trigger a combustion reaction to melt the clathrate hydrate to produce a released methane gas. A first portion of the released methane gas travels along a recovery flow path through the recovery pipe and a second portion of the released methane gas combusts with the oxidant in-situ to perpetuate the combustion reaction.

摘要： In producing methane a bottom hole assembly the borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The enlargement of the borehole can be sensed in real time such as by using a fiber optic cable. In response to such information parts of the bottom hole assembly near the washout can be isolated or the bottom hole assembly in the vicinity of the washout can be fortified with inserts from the surface to minimize damage from erosion caused by higher velocities resulting from borehole washouts.
