Abstract We report about the Early Miocene Tagay fauna of Olkhon Island, largest island Baikal Lake. The is high scientific importance because diversity fishes, amphibians, lizards, snakes, turtles, manifold birds and mammals. lithology, geochemistry fossil record along Tagay-1 section allow reconstruction various palaeoenvironments, i.e. open water, shallow lakes with adjacent wetlands, riveri...

Shale oil reservoirs are characterized by complex lithology, mineral composition and strong heterogeneity. This causes great difficulty in lithologic evaluation. In this paper, a method of lithology identification is proposed means intersection plot machine learning method, evaluation carried out combining the calculation content with multi-mineral optimization model. The logging response chara...

Abstract Lithology identification is critical in the interpretation of well-logging data for petroleum exploration and development. However, limited availability labeled machine learning model training can lead to compromised accuracy lithology classification models. Here, we propose a semi-supervised overcome this challenge. Our framework consists Bayesian optimization tuning ensemble algorith...

the use of temporary runoff and underground dried-up water courses has been implemented by managers in recentyears to compensate for water shortages in arid and semi-arid regions. one way to use this water is to set up anunderground sandy dam in front of such water courses; selecting a suitable water course is the most important issue ofsuch a purpose. in the present research, this matter was i...

Thermophysical properties of rock and soil are important parameters that affect the efficiency shallow geothermal energy utilization. This paper analyzes thermophysical (specific heat capacity thermal conductivity) their influencing factors based on 6467 sample data in 24 provincial capitals, China. The statistical distributions analyzed histogram plots. Linear regression analysis is conducted ...
