Some new data on isotope stratigraphy of the permian rocks at the east of the Russian platform

© 2006-2015 Asian Research Publishing Network (ARPN). Variations of δ13C, δ18O, and 87Sr/86Sr in carbonate rocks and shells of the Permian age at the east of the Russian platform have been regarded. Trends of these isotope ratios reflect the global regression and the increasing of regional environments isolation from the open sea and the arid climate challenges

Oil and gas companies in the russian federation

© 2020, Universidad del Zulia. All rights reserved. The purpose of our research is to develop a model for testing for the impairment of oil and gas company assets. The subject of the research is the set of theoretical and practical aspects of accounting for the recoverability of assets. The object is one of the largest Russian oil companies, Rosneft engaged in the production and processing of oil, as well as the sale of petroleum products. Based on the results of this work, we propose a model for assessing the recoverability of assets based on the calculation of the value from the use of those assets
