A theoretical study has been performed to check the possibility of using ultrabroadband nanosecond electromagnetic pulses as a geosteering tool for horizontal drilling to estimate the distance to the oil–water contact (OWC) in a floating oil accumulation. The voltage of a microwave-bandwidth pulse at the dipole receiver of a downhole radar was modeled for the case of a horizontal borehole near OWC in a formation saturated with oil and water. Numerical solutions to the boundary problem formulated on the basis of the Maxwell equations were obtained with the Microwave Studio software (www.cst.com). The frequency-dependent dielectric constants of the layered saturated formation and the drilling fluid were assumed according to experimentally tested models. The modeling has demonstrated that nanosecond electromagnetic pulses arriving from a layered oil–water contact can in principle be acquired and the distance from the wellbore to the OWC median can be inferred from the respective time delays recorded by a downhole radar. Additionally, the possible dynamic range and accuracy of sensing have been estimated.

An important but problematic component of nuclear geophysical technologies is computer inversion of measurement data based on the equation of particle transport. In this paper, we propose an approach and iterative methods for this inversion that are applicable to many problems of evaluation formation characteristics, including elemental composition, from data of corresponding logging methods. This approach is based on defining characteristic elements, interactions, and trajectories and using the superposition principle for transport processes, and linear a priori constraints on unknowns are used. In comparison with the previous publications of the author, this paper deals with a broader type of measurement data, including the reading ratio of detectors and normalized measurements. The iterative methods are specified for problems of determining the porosity and density from data of neutron–neutron and gamma–gamma logs, respectively. For the first of them, the results of numerical experiments are presented.

The paper considers the Polish exiles’ living conditions as reflected in their memoires. The author analyzes factors that influenced the exiles’ attitudes towards Siberia; studies how their origin, profession, family status affected their living conditions and relations with local population. Special attention is paid to those Poles who returned to Siberia or stayed there after completion of sentence.

The paper deals with the Polish military traveler M. Lepeckiy’s impressions from his journey to Siberia in 1933 and 1936. The traveler’s evaluation of the ongoing changes is presented along with his descriptions of the city of Novosibirsk as contrasted with other Siberian cities.

The paper considers the Tobolsk period of life and activities of an outstanding Russian statesman V.A. Artsimovich, whose “Description of the journey to Siberian land” is introduced into the scientific use. It is shown how his personal impressions from the journey to the North of the Tobolsk governorate influenced his administrative activities.

The article is devoted to the literary and scientific heritage of A.K. Ordynskiy (1830 – 1915). He was a writer and ethnographer, very popular in Siberia in the late XIX - early XX centuries, but forgotten nowadays. Ordynskiy’s literary activity characterizes the Siberian-Polish cultural relations.

The article describes the group of prisoners-of-war from the Polish 5 ^th Rifle Division who lived in the Minusinsk Uyezd in the early 1920s. The group of Polish captives was characterized by social, cultural and political heterogeneity given the fact that in the pre-war period they belonged to three different countries – Austria-Hungary, Germany and Russian empire. The author analyzes educational level, social and professional status of representatives of this group; shows how their labour was used in the regional economy.

The article is devoted to the characteristics of the present stage of the Siberian-Polish academic interaction in historical science. New methodological models in the context of mental history allow expanding the boundaries of human knowledge. The author undertakes analysis of the Soviet scientifi c heritage, reveals a tendency of transition to the new methodological positions, identifies relevant research areas.

The paper determines the level of functionality of citations and titles in the political and social essays of Russian writers in the XVI century in order to reveal specifics of the authors’ styles.

The article reveals factors of creation and existence of hagiography monuments of the Modern Age: specifics of canonization of saints in the Modern Age; the impact of Peter the Great’s «Spiritual Regulation» as a document that determined the contents of hagiographic literature; the role of historical science in transformation of hagiographic literature; specifics of studying hagiographical monuments of the Modern Age.
