Offshore deep water oil drilling
(2023)The difference between offshore deep water drilling of oil wells and shallow water drilling lies in the indicator of the depth at which the work is carried out. The process of extraction of minerals (oil) occurs with the ... -
Oil and gas industry hydrotechnical structures design
(НТУ ДП, 2022)The gradual depletion of oil and gas reserves on land and the aggravation of the global energy crisis necessitated the ever wider development of the oil and gas resources of the seabed, which contains ... -
Oil wellhead equipment
(2023)Regardless of the extracted resource, the mouth is an extremely important functional element of the system. The productivity and efficiency of production, as well as convenience during the drilling process, depend on it. ... -

On formation of electrically conductive phases under electrothermal activation of ferruginous carbonates
(Науковий вісник НГУ, 2017)Purpose. Study of the formation of an electrically conductive phase in carbonates using siderite as an example and determination of the temperature dependence of its formation and silicon content during simultaneous heating ... -
On influence of additional members' movability of mining rolling stock on safety characteristics of the motion
(Видавництво НГУ, 2015)The paper is devoted to mining rail vehicle motion stability while motion on the rail track of steady and transient curvature. Several kinematical schemes of mining locomotives are studied. Assumed, that the most dynamically ... -

On the accuracy of some polynomial approximations for the kolmogorov–wiener filter weight function
(НТУ ДП, 2021)The problem of telecommunication traffic prediction is important for telecommunications and cyber security, see [1]. In paper [2] telecommunication traffic is described as a continuous stationary random process ... -
On the discrete kolmogorov–wiener filter for the one-point prediction of exponentially smoothed heavy-tail processes
(НТУ ДП, 2022)The prediction of telecommunication traffic is an important problem for telecommunications and cyber security, see a detailed description in [1]. There are a plenty of different (and rather sophisticated) ... -
On the formation of a mine-based energy resource complex
(2020)The paper represents the analysis, which has helped to determine tendencies of the formation of energy resource complex based on the available mining facilities. The approach helps prolong operating life of the mine with ... -
