Nikolay Neprimerov (1 May 1921 – 11 January 2017) was a Doctor of Technical Sciences and professor of physics at the Kazan State University. Neprimerov was Head of the Department of Radioelectronics of the Kazan University for 32 years and is author of more than 150 scientific papers and 9 monographs. He also authored a book about the everyday life of military pilots during World War II. He was awarded numerous honours and medals, among them the Russian Federation Government Prize in Science and Technology. Neprimerov dedicated more than 40 years to and is internationally known for physical research in oil recovery.
Biography Nikolay N. Neprimerov (Preobrazhensky) was born on 1 May 1921 in the village of Annovka (Voronezh Region, Russia) to a forest ranger and a schoolteacher. In 1926, his family moved to Kazan. After graduating from School No. 83 with honours in 1939, N. Neprimerov was called up for military service. He was an aircraft technician until 1946, having served four years on the front line. Awarded the Order of the Red Star and medals. In 1946, he became a student at the Faculty of Physics and Mathematics of the Kazan State University to remain there for all his life. He received individual scholarship and graduated from the university in 1951 with honours, continued his studies as a postgraduate under Associate Professor S.A. Altschuler, defended his PhD thesis (1954) and became Doctor of Technical Sciences (1963). During his postgraduate studies, he created a new specialisation – magnetic radiospectroscopy – and participated in the creation of a laboratory for basic research in this field. In 1960, he became Head of the Department of Radioelectronics at the Faculty of Physics and created another specialisation, Radiophysical Measurements. In those years, he developed his own approach to scientific research. When writing his PhD thesis, Neprimerov successively designed three different test installations. He studied microwave polarisation plane rotation and magnetic susceptibility dispersion and determined the dielectric constant for all 36 analysed substances allowing to link, not only qualitatively but also quantitatively, the Macaluso-Corbino effect to electron paramagnetic resonance and to provide a theoretical rationale for this relation. In 1955, Neprimerov became the first in the history of the Kazan State University to be awarded a contract with the Tatneft Petroleum Company. Then, Neprimerov started integrated, in-depth studies of transfer processes in porous media, phase transitions in oil and thermal, hydrodynamic and physicochemical development of oil and gas fields. He analysed thermal and mineral water fields and the Earth's thermal regime for a deeper understanding of the processes in the Earth's interior. By the early 1980s, the data acquired from more than 250 fields employing unique instruments and basic research allowed Neprimerov to create a new technology for the optimal development of oil reservoirs based on an in-depth understanding of fluid displacement in deformed porous media. This technology – increasing production rates and oil recovery while significantly reducing production costs – was the basis for additional development projects designed for the Aznakaevskaya, East Leninogorskaya, Shugurovskaya and Berezovskaya areas of the Romashkino oil field of Tatarstan (Russia). In 1978, Neprimerov created a new faculty at the Kazan State University for retraining oil personnel. More than 200 specialists from all over Russia graduated from this faculty over 10 years. In 1988, the Laboratory of Physical Dynamics of Heterogeneous Media was created at the Department of Radioelectronics, and Neprimerov became its Chief Researcher after retiring from the position of Head of Department in 1992. Nikolay Neprimerov is a three-time winner of KSU's First Prize for the best research work (1957, 1962 and 1993). Along with active research, Neprimerov worked to improve the theory and practice of teaching. About 650 students graduated from the Department of Radioelectronics in the specialisation created by Nikolay Neprimerov. He also gave public scientific lectures on Sundays at the Kazan University attracting huge audiences. During his long life, Nikolay Neprimerov was a member of numerous scientific and technical councils, committees and ministries as well as the USSR Academy of Sciences. He was also a state examiner for the USSR State Planning Committee and a member of academic councils at the Faculties of Physics and Geology of the Kazan State University and at the Kazan Technical University. By his 70th birthday, Nikolay Neprimerov published his most important work, The Universe. Another fundamental work, Physical Dynamics, was prepared for publishing when he was 75. Nikolay Neprimerov also authored a book, Technicians, about the everyday life of military air service personnel during World War II. Neprimerov was married to Galina Anatolievna Neprimerova since 1959. Neprimerov died on 11 January 2017, aged 95.
