Groundwater chemical and microbiological composition in Aptian-Cenomanian deposits (Kaimisovsky oil-gas bearing province)

This paper reveals the investigation results of the groundwater chemical and microbiological composition in Aptian-Cenomanian deposits, Kaimisovsky oil-gas bearing province. The mineral-forming behavior of the groundwater was evaluated. It was determined that the diversity of microbial communities could be corrosive- harmful for the groundwater used in reservoir pressure maintenance systems. According to the research results it is necessary to study the groundwater microorganisms in Aptian-Cenomanian deposits and their influence on groundwater itself.
