according to the design project, or propane osta co breaks down into components in a crack, the rests to the surface and is mined. here we see the final geometry of the fracture, which, in principle, has already occurred here. 300 tons of proppant were pumped and the average fixed length there, and the fracture was 116 m. states of america where this technology is used in the extraction of the so -called shale gas, the problem of using this type of equipment. uh, let's say, the united states associated with the fact that other harmful concomitant substances get into, uh, into we don’t have such problems with water, because ours, let’s say, lie much deeper than the reservoir, given that the technology of hydraulic fracturing allows you to breathe new strength into mature places. with a developed infrastructure and to contribute to more efficient development of fields with difficult geology, the need for hydraulic fracturing equipment will grow. work is underway. and on import substitution, it is in the part of the hydraulic fracturing fleet in the next 2023, already at the wells. abou
