The high potential and new capabilities of the proposed technology are demonstrated on realistic models of well sections of the East-Surgut field (Latitudinal Ob Region). Based on the results of numerical simulation, it was found that electromagnetic signals have a high level and sensitivity to the geoelectric parameters of the Bazhenov Formation, which ensures its cross-well exploration at a considerable distance between wells with sources and receivers. The performed research significantly expands opportunities of electromagnetic sounding by the method of transient processes as applied to the tasks of oilfield geophysics in new formulations.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47799624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first data on the dynamics of peat and carbon accumulation in the oligotrophic bogs of the Baraba forest-steppe of West Siberia in the Holocene were obtained. The peat deposits of these sections, respectively, are mixed multilayer forest-swamp and high moor fuscum, 2.5 and 3.47 m thick, 5254 and 6472 cal. years ago, with total reserves of absolutely dry peat – 200 and 267 kg m–2 and carbon – 91 and 124 kg C m–2. The long-term peat accumulation rates are 37.6 and 40.9 g m–2 yr–1, carbon – 17.1 and 19.0 g C m–2 yr–1, the limits of variation of peat accumulation rates in various periods of bog formation are 14.2–78.8 and 14.8–59.0 g m–2 yr–1, carbon – 6.7–32.6 and 6.8–27.5 g C m–2 yr–1. The dependence of peat accumulation dynamics on the hydrothermal climate regimes of the second half of the Holocene, the genesis and age of sections, and the local conditions of their formation is revealed. The confirmed deposition of peats on lake sapropels and organomineral deposits of reed inundated plains occurred after periods of climate aridization. Significant differences between the subsequent dynamics of peat accumulation and presence and location of primary lakes in bog massifs were revealed.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47933186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of mode of occurrence of Pre-Jurassic rock complexes is based on the interpretation of seismic materials and gravity and magnetic data. The proposed model of the Krasnoleninsky Swell pre-Jurassic basement is characterized by the significantly reduced volume of pre-Cambrian formations due to the expansion of the Paleozoic complexes area, local Paleozoic depressions at the base of the Yem-Yegovskaya and Kamennaya peaks and linear zones of development of Triassic terrigenous-volcanogenic rocks on the Talinskaya Terrace and in the Palyanovsky trough have been identified.
