Sewage disposal: large pressurized fluid is injected the brick house into depleting geological form

Since I am in energetics, I understand how important the brick house it is for our country, about 80 per cent. owned energy to find at least a small source of energy. Aware still pretending to briefly review all the possible benefits and losses. the brick house
Water consumption: Water consumption by using hydraulic fracturing 13-45 thousand. m 3 per borehole. Lithuania averaged predicted 15-20 thousand. m 3 per borehole. In addition, the production of shale gas on the occasion of the drilling disruption may be needed several times during their useful life, in some cases the drilling fracturing the brick house performed 10 times. For each additional wrecking operation may require more water than the former.
Air emissions during normal operations: Texas (USA) found in aromatic the brick house compounds, for example., Benzene and xylene, usually discarded origins of natural gas extraction and processing, where the heavier components are released into the atmosphere. EU emissions of these substances is limited legislation, the brick house but it is important that they are implemented.
It would seem that the majority of accidents and harmful depletion mixture leaks into groundwater caused by improper use of equipment that could be avoided. Eg. US stated that the monitoring of the operations and maintenance quite poor, possibly due to lack of budget authority or for other reasons. Therefore, the main problem - not the lack of regulation and its enforcement in the proper care.
Furthermore, it remains a real risk that methane or other chemicals to penetrate undetected underground water channels (eg. Old disused, but unregistered or improperly užcementuotuose boreholes confirmed unpredictable volatility risk for earthquakes, etc.). the brick house
Contributions from exploding wells or drilling sites after accident: the US experience shows that there have been several the brick house large explosions wells. Most of them written down. It turned out that these accidents are mostly related to inadequate operations carried out by the ignorant or employees, or its improper actions were carried out.
Possible events: from the waste storage tank spills or drilling sludge - reversible fluid and salt solution for the water becomes the brick house contaminated and druskėja; in the event of spills or accidents the brick house in work surface, ie liquid spills from sewage pipes or tanks, non-professional use of the equipment or old equipment; fluid leaked from improperly cemented wells; in the event of spills the brick house through geological formations - by natural or artificial cracks the brick house or channels.
For example, the survey findings and to draw on the aquifers, covering northeastern Pennsylvania and upstate New York and Utik Marcellus shale deposits. Active gas production sites the average methane concentration in drinking water wells was 19.2 mg / l, the maximum concentration - even 64 mg / l, and a concentration already the brick house pose an explosion the brick house hazard. The background the brick house concentration of similar geological structure in the neighboring regions where gas is not fulfilled, was 1.1 mg / l.
Sewage disposal: large pressurized fluid is injected the brick house into depleting geological formations. The removal of the liquid pressure-breaking, methane, various additional compounds and the body of water mixture the brick house is returned to the surface. This water must be collected and properly disposed of. Different sources ranging 9-50% of the water used in hydraulic disturbance gas drilling, going back to the surface. Part of this water is used for dismantling the brick house and recycling of future wells. the brick house
Water contamination due to improper practices: the brick house Accidental during hydraulic fracturing operations have taken place in Europe and, say, Germany. For example, in 2007. were leaks from sewage pipes rock pores accumulated gas field Söhlingen Germany. Groundwater contaminated with benzene and mercury. Although the relevant Lower Saxony mining agency (Landesbergbehörde) properly informed, the public the brick house noticed the accident only in 2011. When the company began to change agricultural soil, which was leaked fluids. (Germany announced a moratorium on shale gas exploration until a safer extraction technology to ensure the security of artesian water).
Earthquakes: 2011. April. small earthquake (1.5 on the Richter scale) occurred in Blackpool, UK, in 2011. June. occurred more (2.3 on the Richter scale). The company Cuadrilla Resources, the earthquake area have engaged the brick house in hydraulic fracturing operations, canceled them and commissioned this case study (Cuadrilla the brick house Resources to carry out drilling in the region since 2010. Autumn).
Chemicals: In the hydraulic disturbance, natural radioactive materials (the RRM) - bedrock found in uranium, thorium and radium - with effluent enters the surface. Sometimes for specific purposes radioactive particles injected with fluids (eg., As isotope
