Results of testing of proppants of various manufacturers are given. It is shown, that for the most of light proppants in a working interval of pressure (27-42 MPa) a degree of permeability reduction advances the density decrease, and high enough crushing resistance of such light proppants is provided not by perfection of their structure, but application of a polymer coating. The necessity to consider these factors at a proppants choice for hydrofracturing carrying out is noted.
