Abstract: Interwell correlation of the complex object YuS2 was carried out on the basis of an integrated approach and an integrated procedure for interpreting the results of indicator studies of various types of cross sections (type 1, 2, 3), using the example of the fields on the eastern slope of the Surgut arch. Simultaneous use of several types of tracers made it possible to detail the data on the hydrodynamic connection between the injection and production wells, determine the existence of inter-layer flows and establish the nature of the distribution of filtration flows and the filtration rate of the tracer fluid. The presented studies increase the information content of field data, provide an opportunity to justify and make design decisions for the development of reserves within a complex reservoir

Resource provision of LNG projects in the Russian Federation and measures to stimulate exploration activities in the Arctic zone
Geosciences

Abstract: The article illustrates the importance of liquefied natural gas (LNG) projects for the economy of Russia. The resource base of ongoing and planned LNG projects in Russia’s Arctic zone and their development plans are considered. The current legislation with planned amendments elaborated to stimulate geological exploration activities to convert significant volumes of the prognosis gas resources to reserves has been analyzed. The proposals promoting geologi- cal exploration in the Arctic zone of the Russian Federation, the plans for acelerated development of the resource base for LNG production and use are discussed

Abstract: Currently, the deposits located within the Fedorov dome structure are at the final stage of development. The share of complex projects under construction containing difficult-to-recover reserves is more than 98 %. All reservoirs are characte- rized by low natural permeability, high clay content, significant water retention ability and heterogeneity in mineralogical composition and reservoir properties. It is important to note that the heterogeneity of rocks in the content of carbonates is generally low and medium, while a complexly built reservoir often contains interlayers with a high content of carbonates. In such conditions, deposits are developed using the technology of clay acid system treatment (aqueous clay-acid compounds with boric acid additives) without prior removal of carbonate compounds
