The objective of this research was to gain insight into the composition and nanostructure of two shale formations, Sargelu and Asmari. Among the techniques used are X-ray diffractometry (XRD), X-ray fluorescence (XRF), thermogravimetric analysis (TGA), field emission scanning electron microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR), FESEM focused ion beam (FIB), and transmission electron microscopy (TEM). According to the XRD results, the main components of both shales were calcite, quartz, and kaolinite. CaO, SiO۲, and Fe۲O۳ were the most common components in both reservoirs, according to the XRF analysis, while P۲O۵, SrO, and MoO۳ were only found in the Asmari formation. According to the TGA study, organic matter and other probable carbonate components comprised ۳۷% of the Sargelu and ۴۰.۵% of the Asmari shales. The organic functional groups were detected using FTIR in both samples. Subsequently, various microscopy techniques were utilized to examine different pores, cracks, and nanostructures in each formation.The objective of this research was to gain insight into the composition and nanostructure of two shale formations, Sargelu and Asmari.
