| A method of measuring the in-situ Total Gas content of an unconventional reservoir rock, the method including: drilling a borehole through a measurement interval in the reservoir to generate an annular volume of drilling mud that includes cuttings and gas, the annular volume having a leading edge and a trailing edge; diverting the leading edge of the annular volume such that all of the annular volume is captured in a degassing storage system without being exposed to atmosphere; discontinuing the diversion of the annular volume when the trailing edge of the annular volume has been captured in the degassing storage system; measuring the gas volume in the degassing storage system to determine the amount of gas per annular volume; and calculating the in-situ Total Gas content of the reservoir with reference to the amount of gas and cuttings per annular volume. | ||||||

| A method and system for producing hydrocarbons from a hydrocarbon containing hydrate reservoir is disclosed. The method includes providing at least one producer well in fluid communication with a producing facility and with a hydrocarbon containing hydrate reservoir. The hydrate reservoir is in fluid communication with a head space disposed above the hydrate formation. The head space contains disassociated hydrocarbons and water. A sweep gas is swept through the head space to remove the disassociated gas and water from the hydrate reservoir and to transport the disassociated gas and water to the at least one producer well. Preferably, the sweep gas is introduced into the head space utilizing one or more injector wells. The sweep gas may be heated. The additional pressure and/or heat provided by the sweep gas may help inhibit the reformation of disassociated gas and water into hydrates allowing for enhanced production rates. The additional heat will also help increase the disassociation rate of the upper part of the hydrate formation adjacent the head space. Non-limiting examples of sweep gases may include natural gas, methane, nitrogen or a mixture of the gases. | ||||||

| The present invention is a method and system for dissociating methane hydrate deposits in-situ. An oxidizer fluid and a supply of fuel, both at a pressure higher than that of the methane hydrate deposit, are supplied and delivered to the methane hydrate deposit. The fuel is combusted downhole by reacting it with the oxidizer fluid to provide combustion products. The combustion products are placed in contact with a diluent fluid to produce a heated product fluid. The heated product fluid is injected into the methane hydrate deposit whereby methane is dissociated from the methane hydrate and made available for extraction. In addition, carbon dioxide may be made available to promote the formation of carbon dioxide hydrates from the liberated methane hydrate 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. | ||||||
