Application of geochemical control methods to confirm the performed geotechnical surveys effectiveness

The article is devoted to the analysis of the possibility of introducing geochemical methods to the deposits of the Northern Caspian Sea to confirm the effectiveness of geological and technical measures (GTM). Offshore de-posits are considered, characterized by a complex geologic...

Catalytic systems for dewaxing diesel fractions

The article discusses modern molecular sieves with different structures that can be used in the processes of dewaxing straight-run diesel fractions. The existing problem is the need to create a catalyst for the isomerization of n-paraffins, capable of ensuring the highest possibl...

Improving the reliability of the offshore platform power system through the modernization of heat recovery boiler registers

The paper presents the results of the reconstruction of heat recovery boilers UK 11-E-5801 A/B/C/D operated at the offshore ice resistant fixed platform (OIRFP) of the V. Filanovsky field. Systemic operational defects of the equipment manufactured by BBS GmbH were identified. The...

Application of geochemical parameters to assess the thermal maturity of the initial organic matter and reservoir fluids of the Astrakhan gas condensate field

The paper considers the application of a set of geochemical indicators to assess the thermal maturity of the initial organic matter (OM) and reservoir fluids of the Astrakhan gas condensate field (AGCF). The relevance of the topic is due to the need to reliably determine the cond...

Alterations in the physical properties of reservoir rocks during the development of oil and gas deposits

The article analyzes changes in the physical properties of reservoirs during the development of oil and gas fields. The impact of processes in the implementation of technologies such as hydraulic fracturing or pumping water into a contour zone is explained. The reason for the sub...

Integrated waterflooding management system based on optimizing well operation through underground reservoirs

The article addresses the problem of water-cut management in the producing well stock of the Astrakhan gas condensate field (AGCF) under conditions of increasing water and gas factor (WGF), limited capacity for handling produced water, and the need to maintain commercial producti...

The influence of the engineering and geological conditions of the Northern Caspian Sea on the geoecological risk of geological exploration within its water area

The article presents an analysis of the key engineering geological conditions of the North Caspian shelf and their impact on the increase of geoecological risks associated with geological exploration and hydrocarbon deposit de-velopment activities. A detailed analysis is provided...

The process operating parameters effect on the extractive ability of some extractants to gasoline fraction dearomatization

In the article considers the extraction dearomatization of a straight-run gasoline fraction using polar solvents – dimethyl sulfoxide and ethylene glycol. The relevance of the study is determined by tightening environmental requirements for the content of aromatic hydrocarbons in...
