Keywords: neural networks, LSTM, temperature rates forecasting, gas wells, corrosion, hydrate formation, Prophet, clustering
The paper proposes an approach to forecasting wellhead temperatures of gas and gas condensate wells based on recurrent neural networks, taking into account the wells classifying by condensate-to-gas ratio. The authors consider the corrosion and hydrate formation issues caused by the thermal mode. There are presented the steps of data pre-processing, creation of new features, development of the basic Prophet model and neural networks (Long Short-Term Memory – LSTM, SimpleRNN, Gated Recurrent Unit – GRU). The models were compared by such metrics: RMSE (Root Mean Square Error) and MAE (Mean Absolute Error), and LSTM significantly outperformed Prophet. Wells’ k-means clustering by condensate-to-gas ratio increased forecast accuracy. The developed model is scalable and applicable for operational forecasting via a web-based application. The results contribute to mitigating emergency hazards, well operation improvement, and reducing inhibitor costs.

The paper presents the performance indicators’ comparative analysis of the acoustic cement bond logging instruments (MAK-2 and Gorizont-90-VAK) used to monitor the quality of casing cementing. The authors defined the fundamental limitations of using Gorizont-90-VAK instruments for assessing a cement-formation-casing bond due to insufficient dynamic measurements range and increased noise levels. The applicability of MAK-2 instrument has been proven subject to compliance with the requirements for its center adjustment. The practical value of the paper is that its results might be used for instruments selection for geophysical well logging, reliability improvement of cementing quality assessment, and developing technical requirements for upgrading the existing line of instruments.

E.A. Evstafeev, B.Sh. Akramov, Gubkin Russian State University of Oil and Gas (National Research University), Tashkent branch
Keywords: methodology, modeling, gas composition, high-boiling component, correlation, adaptation, differential condensation
A methodology has been developed for constructing a compositional PVT model of reservoir fluids, taking into account the specific features of hydrocarbon accumulations in the Republic of Uzbekistan. The application of this methodology is aimed at improving the accuracy of hydrodynamic simulation. The proposed approach consists of a sequence of calculations to be performed in the PVT Designer of a reservoir simulator, enabling the adjustment of the differential condensation isotherm to match laboratory data obtained from a PVT cell. Unlike currently used algorithms, the methodology does not require extensive computational resources or prolonged simulator runtime. Instead, it focuses on varying the parameters that most significantly affect modeling accuracy. The relative error in determining output characteristics does not exceed 5%. The methodology was tested by constructing and calibrating a PVT model of the gas phase fluid for the Yuzhny Kemachi oil and gas condensate field, using experimental data from laboratory studies.

Keywords: carbon dioxide, cleaning systems, chemical-engineering system, ships exhaust gases, spring-of-disks combined chemical absorption equipment
The paper reviews the improvement of chemical- engineering systems used for ships exhaust gases purification and emissions’ reduction of sulfur oxides (SOx) and carbon dioxide (CO2), using spring-of-disks chemisorption-absorption equipment. The research relevance is due to significant volumes of ships’ exhaust gases emissions. International Maritime Organization adopted the emissions control resolution by introducing The International Convention for the Prevention of Pollution from Ships (MARPOL 73/78), which is supported by all member countries engaged in operation and management of ocean transportation. As a part of this matter, currently the exhaust gases cleaning systems with scrubbers (spray absorbers) are widely used to reduce SOx emissions from exhaust gases of vessels’ diesel engines. In order to reduce CO2 emissions, the authors propose to use chemical-engineering systems with a CO2 purification unit, but their application requires the additional devices’ installation. It is proposed to use a spring-of-disks combined chemical absorption equipment, which allows for the absorption of CO2, as well as the sorption of environmentally hazardous sulfur oxides from ship exhaust gases. It has been estimated that the proposed purification unit enables the reduction of CO2 and SOx emissions due to the spring-of-disks combined chemical absorption equipment (instead of a scrubber). The efficiency of the method of CO2 and sulfur oxides removal from low-pressure exhaust gas was confirmed by the outcomes of laboratory studies using the spring-of-disks combined chemical absorption equipment.
