Microbial Community Composition and Function in Jiangsu Oil Reservoir Cores, China.

ABSTRACT: Shale oil reservoirs are typically characterised by elevated temperatures, confined spaces and oligotrophic conditions. Understanding the role of microorganisms in shale oil reservoirs is essential for elucidating biogeochemical cycles and the origins of life. However, the composition and metabolic functions of microbial communities in shale oil reservoirs remain elusive. In this study, shale core samples were collected from the HY1-1 and HY7 wells in the Jiangsu Oilfield. A combination of X-ray fluorescence, powder X-ray diffraction and scanning electron microscope analyses revealed that the samples contained various transition metals, abundant clay minerals and numerous pores with diameters greater than 1 μm. Fractionation of extracted crude oil fractions revealed that HY1-1 and HY7 cont
