TL;DR: In this article, four scientific experimental wells were drilled in the Qilian Mountain permafrost of Qinghai Province, China, in 2008 and 2009 to evaluate the type of clathrates recovered from these sites, including structures containing large and small cages of hydrocarbon gases.

TL;DR: In this paper, the potential studies pertaining to gas hydrate exploration and resource assessment, the safe and efficient exploitation of gas hydrates and the basic properties of gas hyddrates are reviewed.
Abstract: Over the past century, fossil fuels have provided the majority of China's energy. However, their extensive utilization leads to a shortage and environmental pollution. Recently, submarine and permafrost gas hydrate deposits have been investigated as a possible clean and sustainable energy source by governmental institutions, research organizations, and energy industries in China. The primary objective of this paper is to review the potential studies pertaining to gas hydrate exploration and resource assessment, the safe and efficient exploitation of gas hydrates and the basic properties of gas hydrates. To date, there are over 20 institutions and organizations in China committed to gas hydrate investigation, among which the Guangzhou Marine Geological Survey (GMGS) and the Chinese Academy of Geological Sciences (CAGS) etc. primarily focus on gas hydrate exploration research, while the China National Offshore Oil Corporation (CNOOC) Research Center, Guangzhou Institute of Energy Conversion (GIEC) and China University of Petroleum-Beijing (CUPB) etc. concentrate on gas hydrate mining technologies. In this paper, the occurrence and exploration of gas hydrates in both permafrost regions and the continental slope of China have been determined from numerous research contributions and are presented. Moreover, the latest progress in gas hydrate fundamental studies, including hydrate phase equilibria, hydrate formation mechanisms, hydrate thermal physical properties and the acoustics and resistivity characteristics of gas hydrates are briefly reviewed, and relevant data are gathered and compared. Emphasis is also placed on gas hydrate mining technologies and gas production using depressurization methods, thermal stimulation methods or other methods. Furthermore, the security of natural gas hydrate-bearing sediments during gas production and the environmental impacts of gas hydrate are identified. With additional financial and political support and advanced research facilities, research on gas hydrates in China is progressing rapidly but is still in its early developing stage, thus, future work should be undertaken with greater diligence.

TL;DR: An overview of hydrates in nature manuscripts among the 800 papers of the Seventh International Conference on Gas Hydrates (Edinburgh, July 17-22, 2011) was provided by as mentioned in this paper.
181 citations
TL;DR: In this article, the authors highlight the recent advances in fundamental researches, seminal discoveries and implications from on-going drilling programs and field production tests, the impending knowledge gaps and the future perspectives of recovering energy from methane hydrates.
165 citations
TL;DR: In this article, a production model using three different recovery pressures was established to assess the production feasibility from both production potential and geomechanical response, and the simulation results showed that for this special Class 1 deposit, it is a little hard for gas production rate to reach the commercial extraction rate because the degree of hydrate dissociation is limited due to the low reservoir permeability and the permeable burdens.
121 citations
TL;DR: In this paper, the authors used a single vertical well by depressurization method to simulate the gas production potential of the gas hydrate deposits in the Qilian Mountain permafrost.
