The main problem at the oil and gas field is hard-to-recover reserves. The article discusses promising modern methods of increasing oil recovery. The analysis of widely used methods of extraction of hard-to-recover oil and gas reserves is carried out. The Mossbauer studies of the domestic natural mineral raw materials of proppants based on bauxite and aluminum oxides were carried out in order to study the structural and phase features of these materials. Proppants used in hydraulic fracturing to hold cracks play an important role in the oil and gas industry. The Moessbauer method is a powerful tool for studying the structure and electronic state of atoms in materials. It is based on the phenomenon of nuclear gamma resonance absorption and provides information about the chemical environment of the nucleus. In this study, proppants based on bauxite and aluminum oxides were used, which were subjected to a Mossbauer analysis.
