7 Back of Envelope Calculation of CO 2 Utilization Potential in Abu Dhabi for CO 2 -EOR Scenario Conventional EOR+ Advanced EOR+ Maximum Storage EOR+ Description Miscible WAG flood with vertical injector and producer wells in a five spot or similar pattern. Operational practices seek to minimise CO 2 use. Miscible flooding following current best practices optimised for oil recovery. May also involve some second-generation approaches that boost utilisation and recovery. Miscible flooding where injection is designed and operated with the explicit goal of increasing storage. Could include approaches in which water is removed from reservoir to increase available pore volume.

9 Intended Nationally Determined Contribution (INDC) Inclusion of CCUS as mitigation measures: Country CCS CO 2 -EOR Bahrain X Kuwait Oman X Qatar Saudi Arabia X X UAE X INDCs proposed before COP21; CCS accepted as part of future CDM during COP22. Bahrain, Qatar, Saudi Arabia, and UAE emphasized Decision 24/CP.18: Economic diversification with mitigation co-benefits as central pillar of climate action. All emphasized financial, technology transfer and capacity building. Saudi Arabia: CCUS technology development as a response measure. 9

12 CO 2 Sources under Direct State Influence 12

13 Key CO 2 -EOR Drivers for UAE Internal: Sustain Oil production at lower CO2 emissions (clean fossil fuel). Free up gas from gas-eor Diversify economy Source: US EIA External: Carbon credits via CDM? 13

14 CO 2 -EOR Deployment Factors in UAE Institutions - Explicit legislation on state ownership of fossil fuel assets - No explicit regulation for CCS/CO 2 -EOR Stakeholders - CO 2 suppliers: industrial State Owner Enterprises (SOEs) - CO 2 users: National Oil Company (i.e. ADNOC) Operations - Economy: feasible in the ESI project under current oil price - Challenge: large scale deployment 14

15 Major Challenges in Large Scale Deployment Deploying Most Cost-competitive Technology Optimal injection means Optimal infrastructure network CO 2 -Water-Oil-Gas-Renewables-Nuclear-Food Interactions Cost-Revenue-Risk sharing schemes (business model) 15

16 Cost: Significant Learning Cure Effects in CO 2 -EOR Technology Next-generation CO 2 -EOR technology Features: Improve reservoir characterization. Optimize injection well layout and flood design Real time operation optimization. Performances: Improves oil recovery efficiency by 50% More efficient use of CO2 + higher recovery rate greater number of offshore oil fields becoming economically viable.

17 Competing Injection Means for EOR in GCC Alternative methods: gas, water, thermal, chemical, polymer, etc. Key decision factors of injection method: Reservoir characterization Existing recovery method Availability of injection means Amal West (Oman): solar-eor Ongoing EOR projects in Oman: Harweel Field (miscible gas) Qarn Alam Field (thermal) Mukhaizna Field (thermal) Marmul Field (polymer) Amal Field (thermal) New development: Kuwait: steam-eor for Wafra field; 80,000 bbl/d by early UAE: ADNOC & Wintershall MOU on chemical-eor. Saudi Aramco: evaluating miscible gas-eor in addition to CO2-EOR. 17

20 Conclusions CCUS in UAE Now driven primarily by internal rationale (i.e free up gas for EOR) versus external incentives (e.g. carbon credits) focus will be on oil-max versus CO 2 -max. Currently part of a state dominated industrial eco-system. No immediate urgency for explicit regulations: CO 2 -EOR: collaboration achievable among SOEs upon acceptable cost/revenue sharing rules. CCS: lack of clear business models. Discrete decisions on technologies to deploy are critical. Summary: CCUS can be a beneficiary of UAE economy diversification strategy if carefully structured and when proper policy and technology are in place. Actions needed Quantifying the economy of CO 2 -EOR and CCS on levelized basis with pilot projects. Developing clear technological roadmaps for local conditions. Clarifying strategic relationships between CO 2 -Oil-Gas-Water-Renewables-Nuclear-Food. Identifying optimal infrastructure network. Identifying business model and optimal regulation to extend from CO 2 -EOR to CCS. Sharing data for best practice. 20
