Hydrocarbon potential discovered in Eastern South Karanpura coalfield

11 Oct 2024 CW Team

According to a study conducted by the Birbal Sahni Institute of Palaeosciences (BSIP), evidence from microscopic palynomorphs, organic remains, and geochemical assessments has suggested a strong potential for hydrocarbon generation in the eastern region of the South Karanpura coalfield, located in Jharkhand's Ramgarh district.

The study highlighted that the eastern Sirka coalfield demonstrated a higher potential for hydrocarbon generation compared to the Giddi coalfield in the northern part of the region. The South Karanpura coalfield, which encompasses 28 major coal blocks, is well-recognized for its vast coal deposits. However, due to increasing energy demands and a growing interest in unconventional resources like coal bed methane and shale gas, the attention has now shifted towards the hydrocarbon potential of the region.

The scientists from BSIP explained that the potential for hydrocarbon generation within a source rock is primarily determined by the concentration of organic matter, which is influenced by specific environmental factors. The study involved an examination of microscopic remains, such as pollen, spores, and other organic matter, alongside Rock-Eval pyrolysis to evaluate the hydrocarbon potential of sediments from the Sirka and Giddi C areas of the Damodar Basin.

Samples were collected from coal, carbonaceous shale, and sandstone layers from quarry faces at Sirka Colliery and Giddi C Colliery in Hazaribagh district. Analyzing parameters such as palynofacies, free hydrocarbons, pyrolyzable carbon, and residual hydrocarbons, the researchers found favorable conditions for hydrocarbon resource potential, particularly in the Permian (Barakar) deposits located in the eastern section of the coalfield.

ABS Marine Sees CRISIL Credit Rating Upgrade

ABS Marine Services has secured an upgrade to its long term and short term credit ratings from CRISIL, reflecting improved profitability and revenue growth through long term contracts. CRISIL moved the long term rating from BBB+/Stable to A-/Stable and revised the short term rating from A2 to A2+. The action signals strengthened financial metrics and operational resilience. The company benefited from durable client relationships with firms such as ONGC and Schlumberger. The rating decision followed stronger cash flows and an enlarged bank loan facility, which increased from Rs 3,705 million (m..

Project BRAHMANK Marks 16 Years Of Strategic Roads In Arunachal

Project BRAHMANK is marking 16 years of work to establish strategic road and bridge links across Arunachal Pradesh, maintaining and developing 811 kilometres of roads and nearly 86 bridges that range from small culverts to large steel and arch bridges. These transport links are described as critical for ensuring year-round movement of defence personnel, equipment and essential supplies while improving everyday travel for people in remote villages. The project balances national security requirements with regional development by focusing on reliable access in challenging terrain. Notable enginee..

Longleng CSOs Give One Week Ultimatum Over Two-Lane Highway

Civil society organisations (CSOs) in Longleng district have demanded immediate restoration of the deteriorating Changtongya–Longleng two-lane road and sought a detailed status report on the stalled construction within one week. The demand followed a consultative meeting convened under the Phom Peoples' Council (PPC) to discuss welfare and development concerns. PPC president YB Angam Phom said prolonged non-maintenance had caused hardship to commuters and affected transportation, local commerce and the district's development. The meeting urged authorities to undertake immediate restoration a..
