Abstract:With the increasing shortage energy, the exploration and utilization of shale gas (SG) have greatly changed the world's natural gas supply pattern. In this study, based on a bibliometric review of the publications related to SG, by analyzing the co-word networks during the past years, we provide comprehensive analyses on the underlying domain evolution of shale gas research (SGR). Firstly, we visualize the topical development of SGR. We not only identify the key topics at each stage but also reveal their underlying dependence and evolutionary trends. The directions of SGR in the future are implied. Secondly, we find the co-word network has small-world and scale-free characteristics, which are the important mechanisms of driving the evolution of SGR's domain. Thirdly, we analyze China's SGR. We find the co-word network in China's SGR has not yet emerged obvious differentiation. Nevertheless, it has a similar self-organized evolution process with the co-word network of international SGR. Our above results can provide references for the future SGR of scholars, optimization or control of the domain and the strategy/policy of countries or globalization.

“…Shale gas, a kind of clean, efficient and environmentally friendly high‐quality energy, is one of the most realistic alternative resources replacing conventional oil and gas, which is getting increasing attention worldwide . According to the estimate by EIA on global shale gas reserve, the technically recoverable shale gas resources of the 32 major countries has reached 1.63 × 10 15 m 3 , of which 20%, amounting to 3.6 × 10 14 m 3 , is located in China, placing it at the top of the world in shale reserve, and this promises an extremely bright prospect for extraction . Hydraulic fracture is a major technique for shale gas production in North America .…”

The generation of the complex fracture network through hydraulic fracturing is a prerequisite for economic exploitation of shale gas. Bedding planes and natural fractures in shale reservoirs exert a direct impact on the propagation of hydraulic fracture and the formation of the complex fracture network. Based on theoretical analysis and flow‐stress‐damage coupled approach, the propagation of hydraulic fracture under the joint impact of the bedding planes and the natural fractures is studied. The results show the main factors that influence the fracture propagation are the horizontal principal stress difference, the minimum horizontal principal stress, the approaching angle of bedding plane (AABP), the intersection angle of natural fracture (IANF), and the cohesion of the reservoir matrix and the bedding plane. The bigger the horizontal principal stress difference is and the smaller AABP and the cohesion are, the more likely hydraulic fracture will propagate toward the direction of the maximum horizontal principle stress; the smaller AABP and the cohesion are, the more easily it will propagate along the bedding planes; AABP and IANF are the key factors that affect the fracture network formation and both of them bear a negative correlation on the principal stress difference for the formation of the fracture network; the smaller the stress difference and the cohesion difference between the bedding plane and the reservoir matrix are, and AABP is close to IANF and they are in the middle of its value range, the more easily the fracture network forms. The research results are of great significance to reveal the propagation law of hydraulic fracture and the formation of the complex fracture network in shale reservoirs and the efficient exploitation of shale gas.

“…Therefore, at the early stage of the shale gas industry, the motivation and regulation by the government are very important. Some studies pointed out that the success of the shale gas revolution in North America was indispensable to the support from the government, so the Chinese government should publish appropriate incentive policies to promote its shale gas industry, which was still in its infancy [11][12][13][14]. Thereafter, more studies focused on this field.…”

China has accelerated the pace of shale gas development from 2010. A series of policies were issued by the Chinese government to motivate and regulate shale gas exploration and exploitation. In order to investigate the effectiveness of these policies and provide reference to the policymakers, the most relevant policies from 2010 to 2016 were collected and analyzed. Our study summarized that, in total, eight government agencies issued 25 related policies, which cover all the main problems that impede China’s shale gas industry. With the aid of these policies, the approved research and development (R&D) funds exceed 350 million Chinese yuan (CNY) ($55 million), and over 80 domestic companies participated in exploration rights bidding and nine foreign companies initiated thirteen international cooperation projects. In 2016, China’s shale gas production reached 7.88 × 109 m3, ranking third in the world. However, these policies still have some shortcomings, such as low environmental concerns, weak financial stimulus, and inefficient implementation. Therefore, we suggest that future policy should put particular emphasis on (1) formulating special environmental regulations and determining development scale based on water resource; (2) providing detailed implementation plans and maintaining stable subsidy; (3) enhancing communication and supervision; and (4) establishing a public big data platform.
