Shale gas extraction
Podhorský, Jakub ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
This bachelor’s thesis on Shale gas extraction describes extraction and world shale gas resources. At the beginning it provides introduction to the terms of geology and overview of historical evolution of extraction and crucial technologies that are currently used in extraction. Shale gas exploration and extraction development is briefly mentioned. Horizontal drilling and hydraulic fracturing is then further described and also summary of the equipment is provided. Potential environmental risks associated with extraction or hydraulic fracturing itself are described. Subsequently world shale gas resources and potential extraction places are described. World technically recoverable resources are estimated at 7245 Tcf. Shale gas commercial production is currently underway in the United States, Canada and China.

USA and the energy revolution of shale gas
Bednaříková, Markéta ; Bič, Josef (advisor) ; Straková, Eliška (referee)
The thesis refers to the extraction of unconventional shale gas, which is one of the most discussed topics of last few years. It was not considered to be profitable until the end of the 20th century. What made the extraction cost-effective was the combination of hydraulic fracturing and horizontal drilling. While the first chapter characterize the shale gas and informs about the historical development, the second chapter aims at the economic impacts. Falling price of gas caused by the overproduction decreases the costs of enterprises and expenditures of households. The unemployment declines too. The third chapter describes the view into the future and utilization of shale gas in energetics, because the cheap gas makes the electricity production cost less. Then the possibility of gas export will be considered. Shale gas is nowhere extracted as much as in the USA. Therefore, it could be exported abroad. However, the exports of LNG could increase the value of dollar, which could badly affect the exporters of American products.
