With the era of high oil prices and prominent contradict between domestic oil and gas supply and demand, a boom of unconventional natural gas development has set off. While a major success of shale gas development has been made in the United States, it has also brought a successful experience and advanced technology to China. China also have carried out deep research and have achieved certain results in coal bed methane and tight sandstone gas, etc. However, difficulties and problems faced in the development process need to be carefully dealt with .

ABSTRACT In the midst of aggressive anti-drilling campaigns by environmental organizations and well-publicized complaints by citizens unaccustomed to oil and gas operations, rigorous studies of unconventional oil and gas development show that there are no widespread or systemic impacts on drinking water resources in the United States. In addition, air pollution and greenhouse gas emissions have significantly declined with the growth in natural gas production and its use in power generation. Furthermore, induced seismicity from subsurface waste disposal has plummeted in response to industry initiatives and new regulations. This record of environmental protection reflects the fact that U.S. hydraulic fracturing, like other oil and gas operations, is highly regulated by the states. In addition, air emissions, operations on federal lands, and subsurface injection are subject to federal regulation. Academic and government researchers have documented that chemicals and gas produced by hydraulic fracturing are not contaminating drinking water. However, as an added complication, methane occurs naturally in drinking water aquifers in some producing areas. In 2015, the U.S. Environmental Protection Agency (EPA) completed a four-year study of potential aquifer contamination from hydraulic fracturing and associated industry operations. The report found some impacts on drinking water including contamination of drinking water wells; however, the number of cases was small compared to the number of wells hydraulically fractured. The scientific peer-review and public critique of the study, which continues after more than a year, may recommend additional research. The emotionally charged, anti-fracking campaigns provided important lessons to U.S. operators: pre-drilling, baseline data on water and air quality are essential to answering public concerns; infrastructure issues such as increased truck traffic on small, local roads are important to residents; and the initial failure to disclose the composition of hydraulic fracturing fluid intensified public concern.

<p>Although observations show that anthropogenic phosphorus (P) can reach groundwater supplies, there has been no comprehensive evaluation of P in groundwater at the global scale. Additionally, there have been minimal studies on distributed sources, such as agriculture, and the effects of oil and gas activities on P contamination in groundwater are poorly understood. We compile and analyze 181,653 groundwater P concentrations from 13 government agencies and 8 individual research studies in 11 different countries in order to determine the extent of P pollution at the global scale. We find that every country with data has groundwater P concentrations that pose a significant risk of eutrophication to surface waters. In Canada and the United States, we study the relationship between land use, focusing on crop/pastureland, and increased P concentrations in groundwater. In Ontario and Alberta, two Canadian provinces with different histories of oil and gas development, we find areas with a high concentration of P groundwater pollution to coincide with regions of intense oil and gas activity. Understanding the effects of anthropogenic sources on phosphorus contamination of groundwater and identifying all possible pathways through which contamination can occur will assist regulators in planning and implementing effective strategies to manage groundwater and surface water quality and sustain ecosystem health.</p>
