“…Due to the formation of these tiny cracks in natural gas hydrate reservoirs, the permeability of the stratum is then increased, leading to an effective exploitation of the gas hydrate. The microwave heating method has been investigated by many groups, for example, Rachit et al [113] adopted this method for exploitation of natural gas hydrate. In their work, fluorine gas was also used.…”

Natural gas hydrates are cage-like crystalline compounds in which a large amount of methane is trapped within a crystal structure of water, forming solids at low temperature and high pressure. Natural gas hydrates are widely distributed in permafrost regions and offshore. It is estimated that the worldwide amounts of methane bound in gas hydrates are total twice the amount of carbon to be found in all known fossil fuels on earth. A proper understanding of the relevant exploitation technologies is then important for natural gas production applications. In this paper, the recent advances on the experimental simulation of natural gas hydrate exploitation using the major hydrate production technologies are summarized. In addition, the current situation of the industrial exploitation of natural gas hydrate is introduced, which are expected to be useful for establishing more safe and efficient gas production technologies.

Gas hydrate is a crystalline solid consisting of gas molecules, each surrounded by a cage of water molecules. They produce 160 times their volume of methane which is an infinite source of energy waiting to be tapped, but the technology to recover these hydrates is at its infancy. Recovery of gas from hydrates requires the dissociation of gas hydrates which can be accomplished in at least three ways: thermal recovery, depressurization or by chemical inhibition. But, the problems associated are: Most chemical additives (salt, methanol, and glycol) cause pipe and equipment corrosion, ecological problems.Preheated gas or liquid transportation down to hydrate zone is accompanied by extensive heat loss.Microwave or electromagnetic method also requires vast energy transfer to decomposition zone and is inefficient. This paper proposes the injection of air-suspended self heating Ni-Fe nanoparticles (50 nm) in the hydrate formation through horizontal well. These particles will penetrate deep into the class I, II and H hydrate reservoir by passing through the cavities (86–95 nm). The self heating of particles in a magnetic field is caused by hysteresis loss and relaxation losses. These particles cause temperature rise up to 42 °C in formation leading to disturbance in thermodynamic equilibrium and causing the water cage to decompose and release methane. In this technique, the pressure of the fluids in contact with hydrate is lowered, pushing the hydrate out of its stability region and leading to its decomposition. It has been discovered that the less expensive, readily available Eggwhite (Ovalbumin) can catalyze the reaction which results in large scale formation of these nanoparticles. The main advantage of this technique is the very low dosage requirements (small quantity required for 1m3 of Hydrate decomposition). Moreover, the nanoparticles used are non-poisonous, environment friendly.
