“…Thus, the highest production rate of methane gas was produced via the two methods combined together [43]. Roostaie and Leonenko [44] used thermal heating technique to dissociate methane hydrate. The results of the authors' study showed that thermal heating can be successfully applied in gas hydrate dissociation [44].…”

Gas hydrate blockage is a major issue that the production and transportation processes in the oil/gas industry faces. The formation of gas hydrates in pipelines results in significant financial losses and serious safety risks. To tackle the flow assurance issues caused by gas hydrate formation in the pipelines, some physical methods and chemical inhibitors are applied by the oil/gas industry. The physical techniques involve subjecting the gas hydrates to thermal heating and depressurization. The alternative method, on the other hand, relies on injecting chemical inhibitors into the pipelines, which affects gas hydrate formation. Chemical inhibitors are classified into high dosage hydrate inhibitors (thermodynamic hydrate inhibitors (THI)) and low dosage hydrate inhibitors (kinetic hydrate inhibitors (KHI) and anti-agglomerates (AAs)). Each chemical inhibitor affects the gas hydrate from a different perspective. The use of physical techniques (thermal heating and depressurization) to inhibit hydrate formation is studied briefly in this review paper. Furthermore, the application of various THIs (alcohols and electrolytes), KHIs (polymeric compounds), and dual function hydrate inhibitors (amino acids, ionic liquids, and nanoparticles) are discussed thoroughly in this study. This review paper aims to provide a complete and comprehensive outlook on the fundamental principles of gas hydrates, and the recent mitigation techniques used by the oil/gas industry to tackle the gas hydrate formation issue. It hopes to provide the chemical engineering platform with ultimate and effective techniques for gas hydrate inhibition.

“…Natural gas hydrate is typically distributed in marine sediments and permafrost regions and is expected to become a significant successor to natural gas. Therefore, realizing the commercial development of natural gas hydrate sediments possesses significance in ensuring a sustainable energy supply. − Many countries, such as the United States, Japan, China, and so on, have successfully carried out trial production of natural gas hydrate deposits at the moment. − However, the phenomena of low productivity, sanding, unsustainable production, and high development cost have been encountered during trial tests. , Due to the vast cost, it is impossible to figure out the production behavior of natural gas hydrate deposits in detail just through a pilot test by depressurization, − thermal stimulation, − inhibitor injection, − CO 2 replacement − and the joint development technology. − It is an alternative approach to authentically reshape hydrate-bearing sediments and unravel the production characteristics through indoor experiments.…”

A self-developed large-scale 3D platform with a maximal volume of 1695 L and pressure of 30 MPa was employed to investigate the production behavior of hydrate-bearing sediment using depressurization and thermal stimulation technology. Moreover, a novel method involving the joint development of hydrate-bearing sediments and shallow gas was first carried out based on the established apparatus. Experimental results show that the temperature in the reactor exhibits a decreasing trend as a whole with the continuous heat adsorption of hydrate dissociation due to slow heat transfer in the large-scale device. Heat transfer is the main factor controlling the gas production rate in the whole process of depressurization. The temperature of the reactor almost approaches the equilibrium point corresponding to the internal pressure, and the hydrate keeps dissociating near the phase equilibrium curve. Meanwhile, local overpressure is first observed during depressurization, indicating that dissociated gas from hydrate cannot be fully released while some are trapped in the deposits. In addition, thermal stimulation may not be applicable for field-scale marine natural gas hydrate development owing to the large heat loss in the pipelines and the low heat transfer in the sediments. Investigation of the joint development of hydrate-bearing deposits and shallow gas indicates that hydrate hardly dissociates initially at the large production rate of shallow gas and starts to decompose gradually with the decreased value, showing strong interlayer interaction between hydrate layers and shallow gas. Therefore, it is necessary to reasonably allocate the production rate of different reservoirs at different depths to achieve the most economical development during the coproduction of multigas. Compared with that in small-scale experiments, the production behavior in the large-scale experimental apparatus is closer to fieldscale development. Moreover, the first large-scale experimental investigation on the joint development of hydrate-bearing sediments and shallow gas provides novel insight for efficiently developing natural gas hydrate reservoirs.

“…Song et al and Wang et al numerically examined the relationship between heat transfer and hydrate decomposition in a hydrate-bearing core sample and reached a conclusion that thermal stimulation dramatically promoted the hydrate decomposition reaction and gas recovery efficiency in a low-permeability deposit. Roostaie and Leonenko , developed an analytical approach of wellbore heating coupled with hot water circulation and investigated the NGH decomposition behaviors in the reservoir. Yadav et al and Wang et al both proposed a microwave heating technology for NGH exploitation and found that this technology could significantly improve gas recovery and achieve a high energy efficiency.…”

In this work, a new approach of seawater flooding was proposed for offshore natural gas hydrate (NGH) exploitation, whose feasibility was numerically evaluated based on a large-scale NGH reservoir situated in the Shenhu Area of the South China Sea. Then, two artificial means of well location rearrangement and hydraulic fracturing, as well as their combination, were proposed to be incorporated with seawater flooding to promote gas production from offshore NGH deposits. Simulation results indicated that seawater flooding had great advantages over depressurization and could substantially promote hydrate dissociation, effectively prevent secondary hydrate formation, and greatly facilitate gas production. Furthermore, a stable gas production period could be achieved for a long duration, which made the most significant contribution to gas production. The two artificial means of well location rearrangement and hydraulic fracturing could both promote hydrate dissociation and enhance gas recovery, but the promotion mechanisms were different. When these two methods were combined, hydrate dissociation in the whole hydrate-bearing layer could be further facilitated, and a favorable gas production rate could be obtained with a low water production and a high gas−water ratio, which demonstrated great superiority of the combined method over these two methods when used alone. Therefore, it is expected that the newly proposed approach of seawater flooding combined with well location rearrangement and hydraulic fracturing can be applied in the future commercial offshore NGH development.
