Slide 4 Reducing EOR Cycle Time • Develop a common EOR Workflow • Reduce EOR cycle time to proof of concept and EOR FID Characterize thru: – One stop shop: Services and Project Management. Production – Continuity : Same team to stay with the project , Analyze and Predict maintaining knowledge and minimizing handover delays Loop Feedback – Contracting: up front and not tendering at each stage – Integrated approach: for lab, studies, design, implementation, operation, surveillance, proof of concept, EOR FDP Surveillance – Phasing: Lab and studies in parallel with design, not to Implement Measure sequential – Design for Proof of concept : leads to full field EOR FDP in parallel with early pilot expansion – Commoditizing pilot equipment: standardize on modular steam boilers, chemical units, gas supply – Confirmation: Best in class surveillance technology to confirm benefits are achieved by closing the production loop in the shortest time Paper # • Paper Title • Presenter’ s Name
