A method for obtaining gas from gas hydrate formations under frozen layers of earth in cold regions or on the sea floor, comprising the following method steps of; a. drilling a well intersecting a gas hydrate formation, b. placing a stripped production tubing across the gas hydrate formation into the drilled well, said stripped tubing comprising a wall and pre-drilled openings through the wall, said openings being in the form of strips and being filled with a pressure resistant material, the filled openings defining plugs, b'. installing a wellhead, c. selecting a lower elevation in the gas hydrate formation as first targeted level, d. removing water from the well thereby providing depressurization of the stripped production tubing to a low pressure, e. bringing a drilling machine to the targeted level of the gas hydrate formation through the stripped production tubing by means of a drilling machine lowering and controlling equipment, f. drilling the plugs in the openings of the stripped production tubing at the targeted level of the gas hydrate formation by means of a drilling bit of said drilling machine, the width of each opening being wide enough for the drill bit to pass through, g. drilling holes into the gas hydrate formation by means of the drilling bit, pulling said drilling bit back into the stripped production tubing,and allowing for dissociation of the formation to gas and water as a result of the diffusion of the low pressure inside the stripped tubing into the formation through the drilled holes, h. controlling water level and water pressure inside the stripped production tubing and the amount of the produced gas from the wellhead to maintain a low pressure at the targeted level while dissociated gas and water is being replaced by a cavern, i. repeating the method steps e, f, g, h, as many times as there are targeted levels identified in the gas hydrate formation, starting from the lower elevation to an upper elevation associated with a targeted level, j. obtaining the separated gas from the wellhead. a. drilling a well intersecting a gas hydrate formation, b. placing a stripped production tubing across the gas hydrate formation into the drilled well, said stripped tubing comprising a wall and pre-drilled openings through the wall, said openings being in the form of strips and being filled with a pressure resistant material, the filled openings defining plugs, b'. installing a wellhead, c. selecting a lower elevation in the gas hydrate formation as first targeted level, d. removing water from the well thereby providing depressurization of the stripped production tubing to a low pressure, e. bringing a drilling machine to the targeted level of the gas hydrate formation through the stripped production tubing by means of a drilling machine lowering and controlling equipment, f. drilling the plugs in the openings of the stripped production tubing at the targeted level of the gas hydrate formation by means of a drilling bit of said drilling machine, the width of each opening being wide enough for the drill bit to pass through, g. drilling holes into the gas hydrate formation by means of the drilling bit, pulling said drilling bit back into the stripped production tubing,and allowing for dissociation of the formation to gas and water as a result of the diffusion of the low pressure inside the stripped tubing into the formation through the drilled holes, h. controlling water level and water pressure inside the stripped production tubing and the amount of the produced gas from the wellhead to maintain a low pressure at the targeted level while dissociated gas and water is being replaced by a cavern, i. repeating the method steps e, f, g, h, as many times as there are targeted levels identified in the gas hydrate formation, starting from the lower elevation to an upper elevation associated with a targeted level, j. obtaining the separated gas from the wellhead.
