The paper represents a scientometric analysis of a documentary array selected form Web of Science database on the issue "Oil and petroleum products in soil and groundwater." The analysis of the array shows its positive dynamics since the mid-1990s and especially active growth recently; names of the countries and organizations most actively working on the aforementioned problem; authors leading by the number of publications; periodicals and serial publications with high publication activity; scientific meetings that discussed the problems of soils and groundwater contamination by oil and oil products; and the most cited publications. The authors carry out visualization of the scientific field "Oil and petroleum products in soil and groundwater" using CiteSpace software. Documents co-citation analysis with the CiteSpace revealed main research fronts: biotransformation, biodegradation of oil and oil products in the studied media, bioremediation of these media, new research trend related to unconventional methods of oil production. The CiteSpace also lets to identify within the document co-citation network prominent cited publications (according co-citation frequency, betweenness centrality, and the strength of citation bursts). The most prominent research direction-bioremediation-is identified.

Towed streamer positioning is a vital and essential stage in marine seismic exploration, and accurate hydrophone coordinates exert a direct and significant influence on the quality and reliability of seismic imaging. Current methods predominantly rely on analytical polynomial models for towed streamer positioning; however, these models often produce significant errors when fitting to streamers with high curvature, particularly during turning scenarios. To address this limitation, this study introduces a novel multi-streamer analytical positioning method that uses a hybrid harmonic function to model the three-dimensional coordinates of streamers.

Composite biopolymer hydrogel as food packaging material, apart from being environmentally favorable, faces high standards set upon food packaging materials. The feature that favors biopolymer film application is their low gas permeability under room conditions and lower relative humidity conditions. However, most biopolymer-based materials show high moisture sensitiveness and limited water vapor permeability, which limits their application for food packaging.

One of the most challenging aspects of manipulating the flow of fluids in subsurfaces is to control their flow direction and flow behavior. This can be especially challenging for compressible fluids, such as CO, and for multiphase flow, including both water and carbon dioxide (CO). This research studies the ability of two crosslinked polymers, including hydrolyzed polyacrylamide and acrylic acid/hydrolyzed polyacrylamide crosslinked polymers, to reduce the permeability of both CO and formation water using different salinities and permeability values and in the presence of crude oil under different injection rates.

In the process of oilfield development, the surfactant-polymer (SP) composite system has shown significant effects in enhancing oil recovery (EOR) due to its excellent interfacial activity and viscoelastic properties. However, with the continuous increase in the volume of composite flooding injection, a decline in injection-production capacity (I/P capacity) has been observed. Through the observation of frozen core slices, it was found that during the secondary composite flooding (SCF) process, a large amount of residual oil in the form of intergranular adsorption remained in the core pores.

The escalating global concern regarding plastic waste accumulation and its detrimental environmental impact has driven the exploration of sustainable alternatives to conventional petroleum-based plastics. This study investigates the development of antimicrobial blends of bacterial nanocellulose (BNC) derived from plastic waste and polyhydroxyalkanoates (PHB), further enhanced with essential oils. The antimicrobial activity of the resulting BNC/PHB blends was tested in vitro against , , and .
