The article presents results of the detailed petromagnetic analysis of the core samples of the potassium salts of the Kungurian potassium salt complex in the Gremyachinskoe deposit (Volgograd region), which allowed for obtaining additional information on the stratigraphic rhythmicity and for substantiating the correlation levels.

During long-term operation of oil and gas fields in the groundwater on their territory are formed hydrogeochemical anomalies expressed primarily chlorellaman type chemical composition, typical of the zone of active water exchange. The formation of the chemical composition of groundwater is influenced by many factors, both natural and manmade.

The paper presents the results of a study of the insoluble residue of sylvinites and sylvin-halite rocks of the Lower Permian halogen formation, common within the Perelyubsky areas (Western and Eastern), promising for industrial development (Saratov Region) and the Gremyachinsky potash deposit (Volgograd Region). A technique for studying the insoluble residue of sylvinites is presented. The types of insoluble residue are distinguished according to the form of occurrence in sylvinites and its mineral composition is characterized.
