The Impact

Shale gas holds great promise for a countrys economic development and energy independence, but also holds potential perils for the natural resources and the communities. Following the shale gas revolution in the US, China is in full swing to deploy its strategic plan for the shale gas. The Ministry of Land and Resources (MLR) has announced the legal status of shale gas as the 172th independent mining resource, and hosted two rounds of bidding for the commercial development of 23 shale gas blocks. The shale gas revolution seems to may happen in China as well. However, some great challenges exist during the shale gas extraction. One is the impact on water resources for shale gas production, unlike the US, water shortage has been a severe problem in China, hindering its economic development. The other one is that shale gas operations may induce environmental problems, such as accidental spills of flowback water, which contains toxic substances. Spills could have long-term cumulative effects on ecosystems, as with oil spills. This paper highlighted water resources challenges and policy vacuum facing in China. Although the U.S. shale gas experience can assist in identifying some potential issues that Chinese regulators and operators may encounter, policy decision on this issue should be based on risk assessment and regulation studies. For China, there is a long way to lay the groundwork for the shale gas revolution.

Potential Impact

According to the 2011 International Energy Agency data, 60 % of natural gas production in the US comes from unconventional sources. Currently in Europe the commercial production of shale gas has not yet been developed. However, the European Commission estimates that conventional production in those countries which have already made some progress could already start as early as 2015. The 2013 A.T. Kearney report outlines that European resources constitute 7 % of world resources, but the success of shale gas exploration in Europe will depend on a series of economic, political and geographical factors. This paper analyses the potential impact of the development of the shale gas industry in Europe, particularly recoverable potential of shale gas, its impact on the economy, overall EU energy mix, energy prices and the European job market. In addition, the paper briefly discusses the potential impact of shale gas extraction on gas imports and security of supply.

Shale gas is one of the primary types of unconventional reservoirs to be exploited in search for long-lasting resources. Production from shale gas reservoirs requires horizontal drilling with hydraulic fracturing to achieve the most economic production. However, plenty of parameters (e.g., fracture conductivity, fracture spacing, half-length, matrix permeability, and porosity,etc) have high uncertainty that may cause unexpected high cost. Therefore, to develop an efficient and practical method for quantifying uncertainty and optimizing shale-gas production is highly desirable. This paper focuses on analyzing the main factors during gas production, including petro-physical parameters, hydraulic fracture parameters, and work conditions on shale-gas production performances. Firstly, numerous key parameters of shale-gas production from the fourteen best-known shale gas reservoirs in the United States are selected through the correlation analysis. Secondly, a grey relational grade method is used to quantitatively estimate the potential of developing target shale gas reservoirs as well as the impact ranking of these factors. Analyses on production data of many shale-gas reservoirs indicate that the recovery efficiencies are highly correlated with the major parameters predicted by the new method. Among all main factors, the impact ranking of major factors, from more important to less important, is matrix permeability, fracture conductivity, fracture density of hydraulic fracturing, reservoir pressure, total organic content (TOC), fracture half-length, adsorbed gas, reservoir thickness, reservoir depth, and clay content. This work can provide significant insights into quantifying the evaluation of the development potential of shale gas reservoirs, the influence degree of main factors, and optimization of shale gas production.

The Impact

The complexity of the gas transport mechanism in microfractures and nanopores is caused by the feature of multiscale and multiphysics. Figuring out the flow mechanism is of great significance for the efficient development of shale gas. In this paper, an apparent permeability model which covers continue, slip, transition, and molecular flow and geomechanical effect was presented. Additionally, a mathematical model comprising multiscale, geomechanics, and adsorption phenomenon was proposed to characterize gas flow in the shale reservoir. The aim of this paper is to investigate some important impacts in the process of gas transportation, which includes the shale stress sensitivity, adsorption phenomenon, and reservoir porosity. The results reveal that the performance of the multistage fractured horizontal well is strongly influenced by stress sensitivity coefficient. The cumulative gas production will decrease sharply when the shale gas reservoir stress sensitivity coefficient increases. In addition, the adsorption phenomenon has an influence on shale gas seepage and sorption capacity; however, the effect of adsorption is very weak in the early gas transport period, and the impact of later will increase. Moreover, shale porosity also greatly affects the shale gas transportation.

The Impact

Due to the fast growth of the economy and population, the water scarcity issue has aroused widespread critical concern. In fact, reasonable structure, adaptive patterns and effective regulation of the economy, society and water resources can bring a harmonious future. Therefore, the study of how to balance economic social growth and water resources is of great importance. A model of the water resource, society and economy system of the Tongzhou district was designed by Stella. The model established here attempts to analyze future trends in social-economic development and the impact of the economic and population growth on water use in the Tongzhou district under three scenarios. The results reveal that the water shortage is very serious. If the current trends persist, the existing water supply will not be able to meet the water demand in the future. Tongzhou district's water shortage will be 162.50 million m3 in 2020 under the business-as-usual scenario. Therefore, it is necessary to develop unconventional water sources and improve the water-saving capacity of production and life to alleviate the water tensions. This research offers insight into larger questions regarding economic growth and water resource management in general.

Further Development

China is facing a severe situation of energy resources. High oil dependency is seriously threatening our economy’s fast and stable development. The US has successfully achieved the commercial development of shale gas, which has decreased its oil dependency, and also contributed to its natural gas geology and petroleum engineering technology development. Both Chinese and U.S. geological experts predict that China has similar quantities of shale gas reserves as founded in the United States. This paper aims to clarify that producing shale gas resources has economic significance of energy security and environment protection, and scientific significance of promoting the further development of natural gas geology and petroleum engineering subjects.

The Impact

The world tendencies of spatial development, namely the availability of limited resources (primarily water) and the growth of the world’s food needs focus on the resource specialization of the region. On this basis, the purpose of the article is to study the impact of the water-capacious economy on the economic development of the country and its regions. The study used the traditional and special methods, including: historical and logical method – to analyze the functioning of regional socio-economic systems under limited water resources; and system analysis methods – to evaluate the impact of the water-capacious economy on the economic development of the country and its regions. The research results have important implications for the management of the territories. The authors show that the production specialization of the regions of Ukraine on the export/import of water-capacious products is not determined by their water supply. They also suggest that stimulating the region’s water-efficient activity should lead to a minimization of the water capacity of gross regional product and the reproduction of water capital, taking into account the water security of the regions. The authors also show that the water resources of the country and its regions and the natural water potential of the territories in the current situation become significant restriction to the economic development of territories, which allows to state the need to change the approaches to the regulation of regional development based on limited water resources.

Gas Potential

Production of shale gas in the US has changed its position from a gas importer to a potential gas exporter. This has stimulated exploration for shale-gas resources in WA. The search started with Woodada Deep–1 (2010) and Arrowsmith–2 (2011) in the Perth Basin to evaluate the shale-gas potential of the Permian Carynginia Formation and the Triassic Kockatea Shale, and Nicolay–1 (2011) in the Canning Basin to evaluate the shale-gas potential of the Ordovician Goldwyer Formation. Estimated total shale-gas potential for these formations is about 288 trillion cubic feet (Tcf). Other petroleum source rocks include the Devonian Gogo and Lower Carboniferous Laurel formations of the Canning Basin, the Lower Permian Wooramel and Byro groups of the onshore Carnarvon Basin, and the Neoproterozoic shales of the Officer Basin. The Canning and Perth basins are producing petroleum, whereas the onshore Carnarvon and Officer basins are not producing, but they have indications for petroleum source rocks, generation, and migration from geochemistry data. Exploration is at a very early stage, and more work is needed to estimate the shale-gas potential of all source rocks and to verify estimated resources. Exploration for shale gas in WA will benefit from new drilling and production techniques and technologies developed during the past 15 years in the US, where more than 102,000 successful gas production wells have been drilled. WA shale-gas plays are stratigraphically and geochemically comparable to producing plays in the Upper Ordovician Utica Shale, Middle Devonian Marcellus Shale and Upper Devonian Bakken Formation, Upper Mississippian Barnett Shale, Upper Jurassic Haynesville-Bossier formations, and Upper Cretaceous Eagle Ford Shale of the US. WA is vastly under-explored and emerging self-sourcing shale plays have revived onshore exploration in the Canning, Carnarvon, and Perth basins.
