Source rock evaluation of the Gondwana coals in Raniganj coalfield, India
Present study perceived that samples have excellent hydrocarbon generation potential and total organic carbon (TOC) content. The pyrolysis temperature (T-max) indicates that samples are in immature stage (<435 degrees C) for hydrocarbon generation. The hydrogen index (HI) values show that the sample lies in amixture of Type II-III and Type III kerogen. The plot of HI versus TOC implies that samples fall in fair oil source or gas/oil field. Field emission scanning electron microscopy (FE-SEM) and electron dispersive X-ray (EDX) study reveals that the different micro/macro pores and fracture system present mostly in organic substance. In situ gas content values are high enough to produce methane from coal beds.
