| 181 | ENHANCING PRODUCTION OF CLATHRATES BY USE OF THERMOSYPHONS | EP13759591.4 | 2013-08-13 | EP2882931A1 | 2015-06-17 | BALCZEWSKI, John Thomas |
| A method and system for initiating hydrocarbon production from a reservoir (100) are provided. This method and system utilize thermosyphons. The system and method utilize one or more sealed, elongated, hollow tubular containers (A, B, C, D) supported in earth in a geothermal heat zone below the reservoir and extending upwardly therefrom into the reservoir. The containers comprise (a) a bottom portion (400) in the geothermal heat zone below the reservoir; (b) a top portion (300) within the reservoir; and (c) being partially filled with a liquid (200) that evaporates in the bottom portion forming a vapor and transferring heat via convective flow of the vapor to the top portion, the heat being dissipated at the top portion into the surrounding reservoir as the vapor condenses back into liquid and flows downward to the bottom portion. The reservoir can be a natural gas hydrate reservoir. | ||||||

| Clathrate reservoirs of Class II are modified in order to improve the ability to produce hydrocarbons from them. Specifically a method for improving producibility of subsurface clathrate formation underlain by a mobile aquifer includes drilling a borehole to a depth providing access to the mobile aquifer and injecting a material into the mobile aquifer such that the material passes through pore spaces and forms a barrier underlying the clathrate formation and substantially impeding fluid flow from the mobile aquifer into contact with the clathrate formation. | ||||||

| A method and system of producing hydrocarbons from a hydrocarbon containing subterranean hydrate reservoir is disclosed. Waste heat is captured and transferred to a hydrocarbon bearing hydrate formation to dissociate hydrates into natural gas and water. The waste heat can be heat generated from surface facilities such as a Gas To Liquids (GTL) plant, a Liquefied Natural Gas (LNG) plant, an electric or power generation plant, and an onshore or offshore facility producing other conventional or unconventional hydrocarbons from a subterranean reservoir. Alternatively, the waste heat can be obtained from subterranean reservoirs such as hydrocarbon containing producing wells and geothermal wells producing heated water. | ||||||

| A method is provided for recovering oil from a subterranean oil-bearing formation. One or more pairs of electrodes are inserted into the ground in proximity to a body of oil in said formation. A voltage difference is then established between the electrodes to create an electric field in the oil-bearing formation. As voltage is applied, the current is manipulated to induce oxidation and reduction reactions in components of the oil. The oxidation and reduction reactions lower the viscosity in the oil and thereby reduce capillary resistance to oil flow so that the oil can be removed at an extraction well. | ||||||

| A method and apparatus for safely, conveniently, and inexpensively liberating gas from gas hydrates includes the use of a device, provided adjacent to or in the bulk gas hydrates, for exposing the gas hydrates to heat from a gas or liquid (preferably steam). The gas hydrates can be directly exposed to the gas or liquid or indirectly exposed through a thermally conductive coil or channel. The heat from the gas or liquid dissociates the gas hydrates into the corresponding gas component and water component. After liberation, the gas component can be collected for further storage, transport, or use. The apparatus further includes a mechanism for moving at least a portion of the gas or liquid through the device for exposing the gas hydrates to heat. The device for exposing the gas hydrates to heat also can be movable, so it can be maintained in close proximity to or in contact with the gas hydrates for continued efficient gasification of the hydrates. | ||||||

| In some embodiments, a system may include a harvesting unit configured to operate under water to traverse and extract gas from clathrate hydrate deposits. The harvesting unit can include a housing defining an enclosure at least partially open along a bottom portion to receive a clathrate slurry associated with a selected one of the clathrate hydrate deposits. The harvesting unit may further include a separator chamber within the housing defining a negative pressure and configured to receive the clathrate slurry and a skirt coupled to the enclosure adjacent to the bottom portion and configured to form a flexible barrier between the enclosure and an external environment. The skirt may be formed from a plurality of elements configured to allow fluid flow therethrough. | ||||||
