The investigation of fabricated ceramic materials, which can be used as proppants, is presented. Proppants are ceramic materials applied in hydraulic fracturing during extraction of shale gas. Solid slurry pumped with liquid into the deposit causes destruction of the rock structure. The role of proppants is to avoid closing of formed pores and as result enable gas migration from the deposit. Due to processing requirements and conditions in formations (high pressure and temperature), proppants should be characterized by proper physico-mechanical properties. The aim of this work was to elaborate the preparation method of ceramic materials, which can be used as proppants. In this paper results of properties studies of obtained proppants are presented. The influence of raw materials composition, especially the type of applied binder, was examined. Two types of green proppants obtained by the method of mechanical granulation without binder and with poly(vinyl alcohol) in amount of 5 wt% with respect to the powder were used. The properties: bulk density, roundness and sphericity coefficient, grain size and also structure and morphology of proppants was determined by the method of scanning electron microscopy with energy dispersive spectroscopy. The results indicate that composition of raw materials and type of binder have an important influence on the properties of obtained proppants in green state.
