Fracking According to available studies on its environmental relevance, the fracking technology in unconventional natural gas production – particularly in shale gas production – is a technology with enormous potential risks. The effects on humans, nature and the environment are scientifically not yet sufficiently clarified.
As of February 2013, five European countries had bans or moratoriums in place against hydraulic fracturing: France, the Netherlands, Luxembourg, the Czech Republic, and Bulgaria; Romania had recently lifted its moratorium. [56] The flood of shale gas in North America is credited with lowering the price of natural gas in Europe.
Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...
The main tool used by this approach is risk assessment. A risk assessment method, based on experimenting and assessing risk ex-post, once the technology is in place. In the context of hydraulic fracturing, it means that drilling permits are issued and exploitation conducted before the potential risks on the environment and human health are known.
The history of Bulgaria can be traced from the first settlements on the lands of modern Bulgaria to its formation as a nation-state, and includes the history of the Bulgarian people and their origin. The earliest evidence of hominid occupation discovered in what is today Bulgaria date from at least 1.4 million years ago. [ 1 ]
Environmental Protection Agency illustration of the water cycle of hydraulic fracturing. Fracking in the United States began in 1949. [1] According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.
LONDON (Reuters) -Britain on Thursday formally lifted a moratorium on fracking for shale gas that has been in place since 2019, saying strengthening the country's energy supply was an "absolute ...
The Chaika gas field is a natural gas field located on the continental shelf of the Black Sea, offshore of Bulgaria in the Galata block. Discovered in 2013, it was developed by PetroCeltic, determining it to have initial total proven reserves of around 80 billion ft 3 (2.3 km 3).
