proved in American research, the amount of the fluid obtained in shale gas fracturing is lower than in the case of a tight oilfield: 40-60% for a vertical well and 10-30% for a horizontal well [11, 12]. The majority of flowback water outflow takes place during the first hours to a dozen or so days. During contact with the deposit, the fracturing fluid

Hydraulic ,fracturing, is the propagation of fractures in a rock layer by pressurized ,fluid,. Induced hydraulic ,fracturing, or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction. Radionuclides are associated with hydraulic ,fracturing, in two main ways.
