India is one of the countries covered in this study along with China, Canada, Mexico, Australia etc. With current available data, the initial estimates of technically recoverable shale gas resource in these countries is TCF. At present, the shale gas is not exploited in India. Encouraged by the USA results and preliminary USGS assessment, Govt of India is seriously contemplating to carry out detailed exploration, followed by phased extraction.

Related Content: We compared water use for hydraulic fracturing HF for oil versus gas production within the Eagle Ford shale. The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use.

It has been debated whether the fugitive methane emissions during natural gas production and This study estimates the life cycle water consumption and wastewater generation impacts of a Marcellus shale gas well from its construction to end of life. Direct water consumption at the well site was assessed by analysis of data from approximately The rapid rise of shale gas development through horizontal drilling and high volume hydraulic fracturing has expanded the extraction of hydrocarbon resources in the U.

The rise of shale gas development has triggered an intense public debate regarding However, no cost figures were made public for onshore shale gas.

North America has been the leader in developing and producing shale gas. The economic success of the Barnett Shale play in Texas in particular has spurred the search for other sources of shale gas across the United States and Canada , [ citation needed ].

Some Texas residents think fracking is using too much of their groundwater, but drought and other growing uses are also part of the causes of the water shortage there.

A New York Times investigation of industrial emails and internal documents found that the financial benefits of unconventional shale gas extraction may be less than previously thought, due to companies intentionally overstating the productivity of their wells and the size of their reserves.

In first quarter , the United States imported billion cubic feet Bcf from Canada while exporting Bcf mostly to Canada ; both mainly by pipeline.

A recent academic paper on the economic impacts of shale gas development in the US finds that natural gas prices have dropped dramatically in places with shale deposits with active exploration.

One of the byproducts of shale gas exploration is the opening up of deep underground shale deposits to "tight oil" or shale oil production. From Wikipedia, the free encyclopedia.

After an introduction presenting the general context of the recent development of the North American shale gas industry, the first part focuses on the geological factors that control the gas shale prospectivity and productivity. This chapter discusses the impact, variations and measurement techniques of each of these parameters.

The second part focuses on external factors which relate to our ability to technically and economically extract these resources. It includes completion and stimulation methods as well as economical, regulatory and environmental aspects of the shale gas industry.

References Mineralogy and morphology play a very important role in establishing brittleness and therefore controlling its hydraulic fracturing characteristics.

Presence of mixed argillaceous mudstone, silica-rich argillaceous mudstone to argillaceous siliceous mudstone in the studied shale samples shows that the area under investigation is compositionally similar to the high clay facies of Marcellus and Barnett shale systems having low fracability.

The interpreted results of mineralogical brittleness are supported by log based geomechanical properties. FESEM images at micro to nanoscale confirm the presence of various minerals with distinct crystal structure, along with inter-and-intra particle pores in the matrix. AFM scan at the nano scale shows mesopores ranging from 12 to 19 nm, with an average pore diameter of The log derived mechanical properties correlate with the mineralogy-based brittleness index BI of the studied shales indicating that the formations lie in the low to medium range of fracability.

High clay content and low to moderate BI are likely to complicate the fracturing process of the potential resource rich area. Full-text available. Shales and coals can be the source, reservoir, and seal of unconventional natural gas systems. This study summarizes the type, connectivity, and evolution mechanism of micro-nano scale pores in shale and coals. In addition, we discuss the current scientific problems and research limitations on this topic.

It is obvious that a single method cannot fully cover the pore features, and hence the multiple methods are generally used complementary. Characteristics of micrometer-scale pores can be obtained through mercury intrusion porosimetry MIP and nuclear magnetic resonance NMR ; N2 and CO2 adsorption and small-angle neutron scattering SANS are used to analyze nanometer-scale pores. With a combination of the original condition simulation and geochemical screening, micro-nano scale pores can be comprehensively characterized.

The classification of pores should consider possible influences of water and oil saturation, which should be significantly, strengthened in future studies.

We thus suggest using in-situ simulation in association with nano-CT and N2 adsorption to obtain 3D models and volume of pores. The evolution of dissolution can be revealed based on the comparison performed before and after experiments.

Researchers should strengthen the band between the tight unconventional reservoir and micro to nano technology, which would provide an insight into the properties in such scale, seems to be different to conventional understandings to some degree.

Organic-rich mudrock can be the source of, and reservoir for, hydrocarbons, and is abundant with nanopores. The nanoporous networks contribute to gas storage and migration.

Due to the prosperity of shale gas exploration and exploitation, nanopores become a hot spot of nanogeosciences. This paper reviews recent advances on nanopores of organic-rich shales, including nanopore detection techniques, pore classification, pore structures, pore system evolution, and its adsorption and migration features.

The state-of-the-art techniques have been used to achieve nanopore geometry, morphology, structural and matter compositions. Basing on pore morphology, location, origination and host compositions, numerous pore classification rules were built.

Different pore types show diverse pore size distribution features.
