Title of the slide Basic CBM – Business premises § CBM is a front loaded, marginal economics play. § Almost entire CAPEX within a span of 3 -4 yrs - Wells and Surface facilities to be installed early followed by dewatering and CBM production. Potential § CBM production is in early stages. Several fold increase expected when all the blocks start producing in tandem. § Growth driver- CBM occurrence mostly in conventional HC starved area. § CBM is ‘Clean’ form of energy – Increase in Carbon credits. Challenges § Technical: Indian coal basins more heterogeneous and deformed compared to US/Australian counterparts. Continuous R&D and Ingenuity required. § Socio- Economic: LAQ, CSR, Local Awareness etc. Crucial for success. § Policy issues: Favorable Gas pricing will enhance project viability and participation. Overlapping issues with Coal Blocks – clarity on priority & guideline necessary. 9
Title of the slide ONGC Opportunity for Location: ONGC’s four CBM blocks i. e. North Karanpura, Bokaro, Jharia and Raniganj falls in HC starved regions of Jharkhand & West. Bengal – Existing demand for cleaner form of energy for domestic & commercial use. Proximity to Industrial Hubs: Industrial towns of Ranchi, Bokaro, Dhanbad, Asansol, Durgapur falls around these blocks. Establishing a sustainable CBM production is bound to spur its market growth. Proposed Pipeline Project of GAIL: Proposed Jagadishpur-Phulpur-Haldia pipeline will be passing along the CBM Blocks. There is also plan for establishing CGD network in Ranchi, Dhanbad, Singhbhum etc. from this proposed pipeline. 10 # 21 Energy Company in the World
Interference of CBM and Coal Mining § Overlap with Coal Blocks several ONGC CBM Blocks: Ø Parbatpur Coal Block – Jharia CBM Block ØIchchapur & Moira-Madhujore – Raniganj CBM Block § Issues in Simultaneous mining of Coal & CBM. Ø Safety of operations Ø Technological constraints Ø Optimum utilization of natural resources 11 #2 E&P Company in the world
Case Study – Jharia CBM Block Map of Jharia CBM block showing overlapping Parbatpur Coal Block and FDP wells Parbatpur Coal Block Production Hubs § Overlap area with Parbatpur Coal block of SAIL: ~ 8. 0 Sq. Km. § Effect: 27 FDP wells; 10 BCM CIIP. § CBM & Coal Mining activity suspended by DGMS since July, 2014. 12 A FORTUNE Global 500 Company
DGMS suggestion for resolution § Separate working area for ONGC-CIL & SAIL § ONGC-CIL to extract CBM from shallower seams § ONGC-CIL & SAIL to share mine plan to minimize future interference. 13 # 21 Energy Company in the World
