Kazakhstan ranks as the 12th largest oil producer globally and boasts a diverse range of crude oils. This research introduces a method for distinguishing between the different types of crude oils based on biomarker analysis of 28 crude oils from Western and Southern Kazakhstan using gas chromatography-mass spectrometry. Biomarkers serve as valuable tools, especially in forensic investigations of oil spills. These biomarkers effectively retain a significant portion of the original natural product’s carbon structure, providing crucial evidence regarding the origin and identity of the oils under examination. This study identifies a set of biomarkers, including pristine, phytane, n-C17 and n-C18 alkanes, hopanes, bisnorhopanes, iso-copalanes, pregnane, androstane, allopregnane, homopregnane, cholestane, and stigmastane. By examining ratios such as pristane/phytane, pristane/n-C17 alkane, tricyclic/pentacyclic terpanes, and hopane, as well as the distribution of steranes, it was deduced that crude oils from West Kazakhstan exhibited resilience to biodegradation. These findings showed that gas chromatography-mass spectrometry is an effective method for oil biomarkers determination, especially because it provides efficient separation and identification. Additionally, this study delved into the origin conditions and maturity of these oils, contributing to a deeper understanding of their characteristics and analysis that is simple to use and available worldwide.

The problem of eliminating petroleum pollution and its consequences is currently very relevant for Kazakhstan, which is among the ten largest oil-producing countries. The specifics of natural conditions—the sharply continental arid climate—necessitate the development and application of adequate technologies for the restoration of oil-contaminated territories and the Caspian seashore. The key factors (temperature, moisture, alkalinity, salinity, low mineral and organic matter content) affect the self-purification processes and microbiological status of oil-contaminated soils of Kazakhstan. The assessment of taxonomic diversity and characteristics of oil-degrading microorganisms isolated from samples of soils and reservoirs contaminated with hydrocarbons are given. The review of biopreparations and biotechnologies developed and used in Kazakhstan for cleaning environments from oil pollution is made, and their effectiveness is shown. The analysis of the current state of research in the field of biodegradation of hazardous pollutants and bioremediation of oil-contaminated areas allows us to identify promising areas of further work and approaches to the development and improvement of technologies for environmental protection.
