Significant Shale Gas Generation Potential Identified in Eastern South Karanpura Coalfield, Jharkhand
A recent study has revealed the substantial potential for shale gas generation in the eastern region of the South Karanpura coalfield, located in the Ramgarh district of Jharkhand. This discovery is based on the analysis of microscopic palynomorphs (organic remains) combined with geochemical assessments, indicating favorable conditions for hydrocarbon generation. The study highlights that the Sirka coalfield, situated in the eastern part of this region, has exhibited a higher potential for hydrocarbon production compared to the northern Giddi coalfield.
The South Karanpura coalfield, comprising 28 major coal blocks, has long been known for its abundant coal reserves. However, with the growing energy demands and an increasing focus on exploring unconventional energy resources, attention has now shifted towards identifying potential for coal bed methane (CBM) and shale gas in this region. The generation of such hydrocarbons, crucial for advancing green energy initiatives, plays a significant role in India’s energy security strategy.
Hydrocarbon generation in source rocks depends heavily on the concentration of organic matter, which is, in turn, shaped by specific environmental conditions. To evaluate this, scientists from the Birbal Sahni Institute of Palaeosciences (BSIP), an autonomous institution under the Department of Science and Technology (DST), conducted an in-depth study.
Samples for this study were collected from coal, carbonaceous shale, and sandstone layers exposed in the Sirka Colliery and Giddi C Colliery in the Argada area of Jharkhand’s Hazaribagh district. The scientists analyzed parameters like palynofacies, free hydrocarbons (S1), heavy hydrocarbons (S2), pyrolyzable carbon (PC), and residual hydrocarbons (RC) to assess the region’s hydrocarbon generation potential. The findings indicated that the sediment deposits, belonging to the Permian period (Barakar Formation), showed promising conditions for hydrocarbon resource generation.
Published in the Journal of Asian Earth Sciences-X, this research provides valuable insights for future exploration efforts. The data suggests that the eastern part of the South Karanpura coalfield holds high potential for energy resource development. However, further detailed studies are needed to confirm the economic viability of these resources and guide exploration strategies.
The identification of such a significant shale gas resource in the South Karanpura coalfield can play a critical role in enhancing India’s energy independence and reducing its reliance on conventional energy sources. This discovery underscores the importance of continued research and exploration in unconventional energy resources to meet the nation’s growing energy needs. The South Karanpura basin could emerge as a key player in India’s quest for sustainable energy solutions, helping to drive the shift towards cleaner and greener energy alternatives.
Conclusion
The study’s findings underscore the strategic importance of hydrocarbon exploration in the South Karanpura coalfield. With the potential for significant shale gas generation, this region is poised to contribute to India’s future energy mix. As further research and exploration continue, Jharkhand’s coalfields may play a pivotal role in securing the nation’s energy future, supporting both economic growth and environmental sustainability.
