Abstract
The prospects for the gas recovery from bottom gas hydrates are studied, and the necessity for the formation of an innovation environment and practical steps for conducting industrial experiments are formulated. The promising methods of shielded development of seafloor gas hydrate deposits are analyzed and the technical problems of their improvement are revealed. The possibilities of using resonant oscillatory systems for the shielded development of bottom gas hydrates are studied, in particular, a Helmholtz flow-excited resonator. The expediency of using high-quality oscillations of the “rotator” type has been substantiated in order to facilitate controlled gas hydrates dissociation over large areas of a gas hydrate field and to counteract the formation of new gas hydrates in the fractures of hydraulic reservoir fracturing. A method has been developed of gas recovery from bottom methane hydrates using a resonator device, which significantly reduces the energy consumption for the gas hydrates dissociation and contributes to the technological processes control.
Highlights
The total methane gas hydrates reserves are almost an order of magnitude greater than the known reserves of conventional natural gas fields, and potentially represent the most powerful source of mineral energy resources at the planet
The prospects for the energy mineral resources development are largely related to the innovative technologies of the methane crystal hydrates extraction in the World Ocean [1,2,3,4,5,6]
This paper expands on the author’s concept of shielded development of marine gas hydrate deposits, which provides for covering of seafloor significant areas over a methane hydrate field with a system of flexible gas gathering shells connected to bottom gas pipelines
Summary
The total methane gas hydrates reserves are almost an order of magnitude greater than the known reserves of conventional natural gas fields, and potentially represent the most powerful source of mineral energy resources at the planet. 2) George Mitchell invested his personal $7 million into the practical testing of the new method and got a result that has changed the energy “pattern of the world” and brought the United States to the first place in world gas production (“Mitchell Energy & Development” company, as the owner of a revolutionary technology, was bought by the “Devon Energy” corporation still in 2001 for $2 billion) It is the development of new technological methods that are based on the innovative achievements of geotechnologies, as well as the attempts for their practical implementation (with simultaneous improvement and adaptation to development conditions) that is the most effective and economically feasible way to solve these problems. The development of new technological methods of gas recovery from seafloor methane hydrates can contribute to the innovative environment formation that will give a boost to practical pilot-industrial experiments, which will open an energy security alternative direction for many world countries, including Ukraine
