Transcript of "The Potential for Geologic Carbon Sequestration in Indiana"

  1. 1. OUTLINE PART I: GENERALITIES PART II: CCS IN INDIANA PART III: FUTURE WORK AND CONCLUSIONS
  2. 2. • Carbon refers to CO2 or carbon dioxide. • Sequestration means removed or isolated from the atmosphere and stored away for a long time (thousands of years). • US DOE: “a family of methods for capturing and permanently isolating gases that otherwise could contribute to global climate change”. WHAT IS CARBON SEQUESTRATION?
  3. 3. • Manmade CO2 emissions are changing the climate, therefore capturing and storing or sequestering CO2 away from the atmosphere will help mitigate the effects of these changes. • Power generation is changing: •Demand of energy will double by 2030 •Cost of fossil fuel is rising •Green House Gas (GHG) emissions (and concerns) are rising WHY SEQUESTER CO2?

  7. 7. Ocean Sequestration Carbon stored in oceans through direct injection or fertilization. Terrestrial Sequestration Carbon can be stored in soils and vegetation, which are our natural carbon sinks. Increasing carbon fixation through photosynthesis, slowing down or reducing decomposition of organic matter, and changing land use practices can enhance carbon uptake in these natural sinks. Geologic Sequestration The capture, injection and storage of CO2 into deeply buried saline water-filled reservoirs, depleted oil and gas fields, or coal seams. TYPES OF SEQUESTRATION

  17. 17. VOLUME – HOW MUCH IN INDIANA? • Indiana produces ~ 250 million metric tonnes (MMT) of CO2/year (total emissions) • 155 MMT of CO2/year (point source emissions) • If half of the point sources CO2 emissions are to be captured and stored: • ~78 MMT/year reservoir capacity required. • Most are from coal-fired generation plants • e.g. Gibson Station emits ~20 MMT/3100 Mw/year • e.g. Edwardsport emits ~ 4.5 MMT/630 Mw/year • To date, the largest CCS projects store ~1 [MMT/year] • Sleipner and Snøhvit (Norway), Weyburn (Canada), and In Salah (Algeria) • If 10% (7.8 MMT/yr) of the emissions are to be stored, • Will require eight - 1 MMT/year projects

  24. 24. • Base of the sealing interval ≥2500 ft Sufficient lithostatic pressure to ensure CO2 remains in a supercritical state at ≥1070 psi and 88°F • Sufficient sealing strata overlying the storage zone to mitigate the possibility of leakage to shallower intervals and the surface • Porous and permeable storage zone Greater porosity and permeability at shallower depths will allow us to decrease the injection pressure (and therefore costs) • Remote from geologic features that might compromise the integrity of the storage reservoir Faults and fractured intervals CO2 INJECTION: MINIMUM CRITERIA

  33. 33. • The project is designed to build a geologic model for Mt. Simon Sandstone along the Arches province and develop advanced reservoir simulations to determine the infrastructure necessary to implement large- scale CO2 storage. Arches Province ARCHES PROVINCE SIMULATION PROJECT
  34. 34. • Geocellular model will be the basis of the numerical simulations. • Geologic cross sections, stratigraphy, structure maps, deep well injection data, geotechnical test data, geophysical data, geostatistics, mineralogy, geomechanical information, reservoir test data, and other geologic data.

  36. 36. • Geocellular model is being developed using Petrel Software. • Model includes permeability and porosity distribution for Mt. Simon and Eau Claire, corrected at Mt. Simon deep well injection sites. GEOCELLULAR MODEL DEVELOPMENT
  37. 37.  Geophysical porosity logs from 176 wells that penetrate Eau Claire or deeper were compiled into a 3D database.  Database contains a total of ~960,000 data points from Knox, Eau Claire, Mt. Simon, and Precambrian interval. GEOCELLULAR MODEL DEVELOPMENT

  39. 39. GEOCELLULAR MODEL DEVELOPMENT (CONT.)
  40. 40. • Currently, numerical simulations are being developed based on the geocellular model and initial conditions. • Initial variable density flow simulations and scoping-level simulations are being run to assign model grid, boundary conditions, and solution parameters. • Basin-scale, multi-phase model will be developed based on initial model results. NUMERICAL SIMULATIONS
  41. 41. • There are 52 point sources in the area with emissions greater than 1,000,000 metric tons CO2 per year. These source have total emissions of 262,000,000 metric tons CO2 per year. • To reduce greenhouse gas emissions in the Arches Province 25-50%, CO2 storage projects with total storage rates of 65-130 million metric tons CO2 per year would be necessary, suggesting regional storage fields. • MIT CO2 Pipeline Transport and Cost Model was used to determine potential CO2 storage field location in the Arches Province based on intersection of optimum pipeline routes to favorable sink locations. REGIONAL STORAGE FIELD SIMULATIONS Source: MIT pipeline transport and cost module (http://e40-hjh-server1.mit.edu/energylab/wikka.php?wakka=MIT)
  42. 42. • Preliminary flow simulations have been completed to examine pressure buildup due to large scale injection in the Mt. Simon SS. • Model results help determine boundary conditions, grid spacing, and solution parameters. Delta Pressure- 7 X 2.0 million metric tons/y per well (14 Mt/yr total injection) PRELIMINARY VARIABLE DENSITY SIMULATIONS Source: Battelle, 2011 (Pers. Comm.)
  43. 43. • The work will represent the “next step” in simulation of CO2 storage — the widespread application along a major, regional geologic structure in an area of the country with a dense concentration of large CO2 sources. • As such, it will help answer technical and infrastructure questions related to simulation methods and also contribute to research on monitoring options and risk assessment.

  44. 44. 1. The last decade has seen tremendous progress in our knowledge of sequestration potential in the Midwest: The regional geologic and terrestrial frameworks are generally well understood, major sinks have been identified. 2. Studying the relationship of porosity, permeability, and depth helps us to understand the reservoir characteristics in terms of storage capacity and efficiency for CO2 sequestration. 3. Storage capacity estimations suggest that Indiana has a high geologic potential for the injection of CO2. CONCLUSIONS
  45. 45. 4. The static models of storage capacity need to be validated with injection of CO2 into the targeted reservoirs, which will provide insight on the suitability for injection of bigger quantities of CO2. 5. Numerical simulations will help us understand the distribution of the CO2 plume within the injection interval. CONCLUSIONS (CONT.)
