The European Union has a comprehensive 300-page report, which hidrobreking to shale gas to exploit

A few years ago the average South African would have thought the term "fracking" is a way to the internetsensors, bad language block to bypass. Today is "fracking", or do hidrobreking, a hot potato to many opinions, arguments and counter arguments evoke.
In September last year, the South African cabinet approved the moratorium on hidrobreking exploration millinery in the Karoo lifted, and so paved the way for exploration applications to be considered. However much water should happen before possible exploration can begin. While the possibility of far-reaching consequences for South Africa, most of us still understand very little of hidrobreking.
Fracturing as a method to shallow hard-rock oil wells through liquid and solid nitroglycerin stimulate, already in the 1860s by American olieproduseerders, and later also for water and gasboorgate. The idea rather a non-explosive acid, originated in the 1930s. A Rider of the hours that the cracks did not completely shut due to the etching of the acids on the rocks. The discovery was later improved with the addition of proppante the cracks open.
The exploration and possible exploitation of shale gas in the Karoo is so named because of the type of rock formations in which the gas is trapped. Shale rock a fyngekorrelde millinery sedimentary rock composed of a variety of minerals millinery and mud. Due to the high porosity and low permeability of shale rock, a lot of research and technological development needed before hidrobreking for shale gas could be used, and is the most economically viable smooth water method first used in practice in 1997.
The process millinery involves a borehole drilled to the desired depth in the Karoo process first vertically and then horizontally. Then hydrolysis (smooth millinery water) fluids pumped under high pressure into the well to crack the rock open. The hydraulic fluid stay course voortbeur until the high-pressure flow closed. It extended the cracks formed. To prevent cracking chance again after the pressure of the fluid is cut off, a proppant (such as sand, ceramic, or something millinery similar) with the fluid in the borehole and pumped brekingskrake. The spaces between the solid-proppante makes it possible for natural gas to figure out and tanks on the surface to be collected. millinery
The hydraulic fluids used is determined by the type of strata by breaking should take place. It can range from a simple mixture of water and salt, to complex millinery combinations, different substances such as acids and methanol. The purpose of the fluid is twofold as it is on the one hand the breaking achieved and other proppant output to the newly formed cracks open. It is for this reason that became the hydraulic fluid mixtures in order to ensure a smoother output of the proppant and thus the cracks bigger and more stable. Thus enhance production of the mine. To monitor millinery the condition of the cracks, radioactive tracers millinery are also included in the liquid. The radioactive materials are chosen millinery to minimize initial and remaining bestralingsbesoedeling millinery caused. Strict millinery measures determine the type and amount of radioactive particles per unit liquid may be used.
The European Union has a comprehensive 300-page report, which hidrobreking to shale gas to exploit as a high risk to human health and the environment is criticized, launched on the same day that the moratorium on hydraulic fracturing exploration by the South African government lifted . The statements in the EU's report stems from two main arguments against millinery hidrobreking, namely the potential of the process to contaminate water sources or to exhaust and air pollution.
In a water-poor country like South Africa, the protection of water resources is essential. Pollution threats to water include the chemicals that are used to smooth water mixture together, can contaminate groundwater. The danger is that the shale gas by the natural fresh water water banks (aquifers) rate and the water is so polluted. The health hazards of contaminated water for humans and animals can be fatal. In the United States, where hidrobreking have used for many years, several millinery cases of groundwater contamination already reported. Moreover, in order a break mynkraking of the proposed Karoo plan, up to 20 million gallons of water used. Royal Dutch Shell, which has applied for an exploration permit, undertook to bring the water and not the Karoo farmers millinery to compete this limited resource.
Recent research from the United States, some of the concerns about water pollution slightly resolved. If smooth water on the surface
