1 EOR Competence along the Value Chain Ana Todosijevic April 25, 2018

2 Agenda A Thought The Two EOR Golden Rules EOR Value Chain Cooperation between E&P Partners Assessment of EOR Strategy Understanding your Reservoir Chemical Selection, Upscaling and Logistic From Pilot to Full Field, how to make it faster? Conclusion 2

3 A Thought Conventional Oil & Gas production is facing tremendous challenges: Volatile Oil Price CAPEX intensive development of new projects Competition from unconventional- and renewable energies Need for optimization of the carbon footprint Negative public perception which leads to: Shifting of capital investments towards renewables Decreased interest of young professionals to work in our industry Are we as a industry active enough to manage this challenge? How can we improve the performance of our existing and new projects? Global upstream investments (bill. US$) 1,200 1,100 1, Source: Lambert Energy, Wood Mackenzie, Rystad 3

4 The Two EOR Golden Rules EOR is not a method or a random combination of methods, but a synergetic and optimized strategy EOR needs to be considered early in the planning stage of a new project and should be part of the production plan of a reservoir from day zero 4

5 EOR Value Chain 1 Assessment of EOR suitability 2 Subsurface Evaluation 3 Chemical synthesis 4 Chemical Upscaling 5 Formulation 10 Impact oil/water processing 9 Logistics 8 Field Application Design, Execution & Monitoring 7 Business model & Commercial 6 Upstream laboratory Core flood 5

8 One Team Approach with Lundin Edvard Grieg Field License Lundin (operator), 65% OMV (20%) Wintershall (15%) One Team Approach between Wintershall and Lundin in Primary-, Advanced Screening, development of the Facility and Logistic Concept and the planning of the needed laboratory experiments 8

9 Assessment of EOR Strategy EOR Screening already in the field development phase Field Development Plan to allow for EOR application Based on the geological- and reservoir properties Establishment of the optimal EOR Strategy Based on standalone- or combined methods 9

10 Understanding your Reservoir Geological Model Understanding of geological uncertainties Reservoir Model Up to date history matched model Capturing all available SCAL data and updated geological interpretation Utilization of Digitalization 10

11 Chemical Selection, Upscaling and Logistics Close cooperation with the chemical supplier Selection of suitable chemistry Fast upscaling from lab to production Tuning of physicochemical properties Compatibility with Used production chemicals Materials Efficient & effective logistics chain Reducing shipping costs Optimizing delivery schedule Reducing carbon footprint 11

12 From Pilot to Full Field, how to make it faster? Assemble the EOR value chain as a one-team approach Plan for EOR in the Development Phase of the project Each company involved must have access to all required information Excellent project management, assign clear responsibilities Apply a simultaneous, integrated workflow EOR Pilot as part of full field deployment Perform work in parallel wherever possible Work in short iteration cycles from concept to execution Work with an innovation-driven culture Terminate projects early if they do not meet expectations Implement an open, failure-tolerating culture 12

13 Conclusions Make EOR part of the Development Plan Assess early the EOR Potential Understand your reservoir Allow field development plan to account for EOR application Project Management One goal for all parties Simultaneous, integrated workflow Work with an innovation-driven culture Integration along the EOR Value Chain One team approach Share neccesary data with all involved suppliers Collaborate Industry-wide cooperation between operators Stop reinventing the wheel Share successes and failures to educate all E&P companies 13
