Project for shale gas in Ukraine is fraught environmental and social issues, if companies use dangerous technologies, the cost is not yet clear "blue fuel", the expert of the International Socio-Ecological Union, Alexei Grigoriev.
Against the background of protracted and fruitless negotiations with Russia to reduce the cost of imported gas Ukraine increases domestic production, placing hopes on the development of fields of the Black Sea as well as the extraction of unconventional shale gas. In May, Ukraine held a competition for an agreement on production sharing Yuzovsky Olesko and shale gas, the winners of which are recognized by Shell and Chevron, respectively.
"Most of all, go to the Ukraine with waste, the traditional water technology (hydraulic fracturing — ed.) … Companies can classify the chemical composition of the solution, which will be pumped into the ground, citing commercial confidentiality. Next point — is the land issue, thousands tens of thousands of wells — it is reality. Each well — is a platform, a herd of huge powerful truck is broken road … These social aspects should be allowed from the start "- Grigoriev said at a news conference at RIA Novosti.
The expert noted that there are benign to the environment and relatively clean technologies for extracting shale gas, but they make it cost a lot more expensive.
"Most of the problems can be solved, but it should be the desire and the economy, that is the cost. Possible to make everything nice and good, but then it will cost significantly more. Economy will depend heavily on what will be found. In Ukraine, we do not know the economic parameters of what was found and find him, "- said the expert.
Hydraulic fracturing — a method that allows the development of shale gas. It lies in the fact that in the gas-bearing layer of rock under high pressure is pumped into a special mixture of water, sand and chemicals. In the gas-bearing layer of pressure cracks through which hydrocarbons seep into the well. This technology is of great criticism of environmentalists and is banned in several countries, including France.
