The webinar will focused on ‘The Global Status of Carbon Capture & Storage & CO2-EOR’ and briefly touched on the potential role of EOR-CCS in the Venezuelan technical context. The Institute is pleased that Vanessa Nuñez, Research Scientist Associate at the Gulf Coast Carbon Center of the University of Texas at Austin’s Bureau of Economic Geology, is presenting this webinar series.

Vanessa serves as Principal Investigator for several applied CCS projects. She holds a BS in Petroleum Engineering from Universidad Central de Venezuela, an MS in Petroleum Engineering from the University of Texas at Austin and an MA in Energy and Mineral Resources also from the University of Texas at Austin. Before joining the Bureau of Economic Geology, Vanessa was a Senior Reservoir Engineer at Chevron Energy Technology’s Carbon Storage group, where she served as company representative for several Joint Industry Projects, such as the Weyburn-Midale IEA project. Back in her native Venezuela, she worked as an Instructor Professor at Universidad Central de Venezuela.

  • 3. QUESTIONS  We will collect questions during the presentation.  Your MC will pose these question to the presenter after the presentation.  Please submit your questions directly into the GoToWebinar control panel. The webinar will start shortly.
  • 4. The Global Status of CCS Vanessa Núñez López, M.S., M.A. vanessa.nunez@beg.utexas.edu
  • 5. Achieving a low carbon future: A call to action for CCS The Global Status of CCS: 2013 – The key Institute publication  2013 edition: released 10 October  Comprehensive coverage on the state of CCS projects and technologies  Recommendations for moving forward based on experience  Project progress outlined since 2010 5
  • 6. CCS: A vital part of our low-carbon energy future
  • 7. CCS well understood and a reality 7
  • 8. EOR continues to drive development 8
  • 9. Important gains but project pipeline reduced 9
  • 10. Need long term commitment on actions to mitigate climate change  ƒ CS progress is currently below the pace required C to make a significant contribution to climate change mitigation  In the Institute’s project survey 70 per cent of projects agreed that policy uncertainty was a major risk to their project  Pipeline of projects could then shrink further, placing climate change targets at risk RECOMMENDATION 1 Implement sustained policy support that includes long-term commitments to climate change mitigation and strong market– based mechanisms that ensure CCS is not disadvantaged 10
  • 11. Strengthen incentive mechanisms to support immediate demonstration 11
  • 12. Support needed for first mover projects  ƒ eed robust projects to move through the N development pipeline and commence construction  The value of CCS must be continually affirmed  CCS must not be disadvantaged in relation to other low-carbon technologiesƒ ƒ RECOMMENDATION 2 Boost short-term support for the implementation of demonstration projects. This will require targeted financial support measures that enable first mover projects to progress faster through development planning into construction and provide necessary support during operations 12
  • 13. Some power generation projects are in the pipeline 13
  • 14. Goals remain challenging 14
  • 15. Dealing with regulatory uncertainties  Some important legal and regulatory progress  ƒ espite this several issues persist D  Includes post-closure stewardship and cross-border movement of CO2 RECOMMENDATION 3 Implement measures to deal with the remaining critical regulatory uncertainties, such as long-term liabilities. This will involve learning from the efforts of jurisdictions within Australia, Canada, Europe and the US, where significant legal and regulatory issues have been, and continue to be, resolved 15
  • 16. Meeting the energy needs of developing nations  With a pressing need to build large amounts of generating capacity, emissions could increase dramatically without CCS  Overall CCS is at the very early stages in many developing countries  Encouragement is needed to consider CCS and if so help with implementation  Significant progress is being made in some countries to advance CO2 storage programs and CCS regulation 16
  • 17. Support R&D and collaboration  Much can be learnt from large pilot projects, especially in industries where no large-scale projects exist  These projects are crucial for reducing costs and strengthening investor and stakeholder confidence  Need to address gaps in iron and steel and cement  Globally collaborative R&D more cost effective RECOMMENDATION 4 Continue strong funding support for CCS research and development activities and encourage collaborative approaches to knowledge sharing across the CCS community 17
  • 18. Storage pilots and demonstration projects have an important role 18
  • 19. Planning for storage site selection  Storage screening is important but there is also a need to focus on maturing demonstration project storage sites  Storage site selection can take 5–10 years or more  Currently limited incentives for industry to undertake costly exploration programs RECOMMENDATION 5 Create a positive pathway for CCS demonstration by advancing plans for storage site selection 19
  • 20. Encourage shared infrastructure  Scale of infrastructure required for CCS to help meet climate change mitigation targets is great  ‘Trunk lines’ that connect capture projects with storage formations could allow for:  lower entry barriers  optimal development of infrastructure RECOMMENDATION 6 encourage the efficient design and development of transportation infrastructure through shared hub opportunities to become ‘trunk lines’ for several carbon dioxide capture projects 20
  • 21. Action needed  Encouraging progress with 12 projects in operation  But we must deal with the decline in the project pipeline  Short term injection of support required to help demonstration projects proceed and to build confidence  Need to ensure that CCS can play its full part in climate change mitigation and in providing energy security  Above all action on long-term climate change mitigation commitments is key to the deployment of CCS  Time to act is now 21
  • 22. How the Institute is committed to the challenge 22
  • 23. CO2-EOR basic concepts What is it? CO2-EOR is a technology that targets the residual oil in depleted oil reservoirs by the injection of carbon dioxide (CO2). Where is it applied? In depleted light-oil reservoirs that have gone through primary recovery (natural flow) and, in most cases, secondary recovery (mainly waterflooding). How does it work? CO2 is a solvent: it mixes with the oil • Oil expands (swells) • Oil viscosity is reduced • Interfacial tension (IT) disappears* 23
  • 24. Minimum Miscibility Pressure (MMP) At constant temperature and composition, MMP is the lowest pressure at with miscibility can be achieved. At MMP, the interfacial tension is zero and no interface exists as the fluids have become one single phase. Miscibility: two fluids are miscible when they dissolve in all proportions producing a homogeneous solution. Miscibility goes beyond solubility! • First contact Types of Miscibility • Multiple contact • Miscible: Above MMP Types of Flooding • Immiscible: Below MMP Depending on temperature and oil composition, MMP values can be achieved in oils ranging from 35 to 40 API 24
  • 25. The extra-heavy oil challenge CO2-EOR cannot be applied directly to heavy or extra-heavy oil fields, at least in its conventional form. However, there exist EOR options in which the development of such fields could be considered as part of broader multicomponent CCS projects Options include: High CO2 emitting conventional and unconventional thermal processes, where CO2 is captured, transported, and injected into nearby light oil reservoirs or saline aquifers. • Steam injection • In-situ combustion CO2 captured and transported Miscible oil fields Near-miscible oil fields Gas fields Deep saline aquifers 25
