Hydraulic fracturing technology originates in the late forties. Since then, its popularity grew, that by the end of 1955 made more than 100 thousand treatments [1]. Currently, it is the most common method of stimulation of oil and gas wells in unconventional reservoirs. The point of the fracturing treatment is to create a propped fracture, which has good conductivity and permeability after the fracturing fluid is flowed back. In practice, the key parameter in determining the permeability of proppant pack is its porosity. Small changes in the porosity of proppant pack result in significant changes in the permeability of the pack and the fracture conductivity. Rapid loss of fracture conductivity after hydraulic fracturing treatment is often considered to be the result of particle formation migration in proppant pack or form the particles resulting from crushing of the proppant [6]. Forming of minerals may occur in the proppant pack because of chemical differences between the formation and the proppant. As a result of these reactions, proppant pack porosity may decrease.
