  1. GONDWANA BASINS-POTENTIAL STORAGE SITE FOR CO2 By G. Mukhopadhyay Geological Survey of India

  2. CARBON SEQUESTRATION CAPTURE TRANSPORTATION INJECTION OF CO2 INTO FAVORABLE SITES POST INJECTION MONITORING

  3. Produced oil or gas Overview of Geological Storage Options Injected CO2 Stored CO2 Basalt Deep seated coal seam as a a sink of CO2 with enhanced CBM recovery Depleted oil and gas reservoirs Deep saline aquifers- onshore Enhanced oil and gas recovery Deep saline aquifers- offshore

  4. FIELD EXPERIENCE- US • Allison CO2-ECBM Pilot • Location- San Juan basin • Producer well—16 • Injector well—4 • Average depth to top coal - 3100 feet • Permeability 100md • Initial pressure – 1650 psi • Temp. – 160oF OBSERVATION • CO2 injection improved methane recovery from 77% to 95% of OGPI • Ratio of injected CO2 to produced CH4-3:1

  5. FIELD EXPERIENCE- CANADA • Alberta Research Council • Location- Fenn BIG Valley, Alberta Province • Producer well—1 • Injector well—1 OBSERVATION • injectivity improves with continued CO2 injection and methane production

  6. FIELD EXPERIENCE- JAPAN • Operated by JCOAL • Location- Yubari site, Ishikari Coalfield • Producer well—1 • Injector well—1 OBSERVATION • Gradual increase of injection rate –may be due to decrease in effective stress near injection well area. • 90% of injected CO2 stored in coal seams • Gas production increase with CO2 injection, and dropped after injection was stopped- indicating ECBM effect

  10. COALFIELDS OF INDIA RAJMAHAL – BIRBHUM MASTER BASIN Important geological locales for storage 1. large aerial extent. 2. Coal seams ( > 50m) occur beyond 1.0 Km depth. 3. Thick Cap rock. 4. Close proximity with the thermal power stations and other industrial activities. RANIGANJ BASIN WARDHA –PRANHITA – GODAVARI BASIN CBM blocks are allotted in these coalfields.
