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.

Hydraulic fracturing
Mazáček, Michal ; Mls, Jiří (advisor) ; Fischer, Tomáš (referee)
This bachelor thesis deals with the process of hydraulic fracturing. Hydraulic fracturing (also called fracking or fracjob) is a method used for the stimulation of the oil or gas reservoirs. The point of the method is to inject the liquid under high pressure into the formation. The injection cause widening of existing fractures or making new ones. The goal of this thesis was to describe basic knowledge that are necessary to successful treatment. There were basics of rock mechanics described such as linear elasticity, plasticity etc. The main chapter describes the parameters of the fracture such as fracture wide, fracture height, fluid flow and fluid loss. Furthermore, the kinds of liquids were discussed in one chapter. In the end, the fracturation which had been done in Texas(USA) were shown and the spreading of the fractures were discussed.

Obama Administration's Approach Towards Fracking: Environmental Agenda As a Priority or Secondary Issue?
Povincová, Michaela ; Sehnálková, Jana (advisor) ; Pondělíček, Jiří (referee)
Hydraulic fracturing represents a significant part of the growing mining and oil industry. The most significant fracking expansion occurred during the period of Barack Obama, whose statements during his candidacy were directed against the oil industry. Based on this, environmental advocates expected Obama to seek to regulate fracking. Under the pressure, Obama was forced to take some steps against fracking, but they could not be so drastic as to create too much complication for the industry. The present work analyzes the steps and regulations adopted by the Obama administration, along with the reactions of supporters and opponents of fracking to the measures. Based on this analysis, the work points out that despite the Obama administration's efforts to introduce regulations to protect the biosphere and communities around fracking, the measures were insufficient and in some cases did not raise any standards for the oil industry. The work also found that due to the significant impact of fracking on the US economy, Barack Obama could not afford to set stricter regulations and in many cases combined the solution of environmental problems with economic solutions or with national security or energy independence. Based on this analysis, it can be concluded that the Obama administration has prioritized US...

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.
