سلام روزتون بخیر Economical feasibility study and case studies eor project case State of asphaltene in crude oil and application of nano-chemicals for aggregation inhibition: A comprehensive review Title: EOR Processes Optimization: Case Study --- 1. Abstract Clear summary of the study objectives, methodology, data used, optimization approach, and key results. Mention the field/case study (without confidential details). Highlight improvements in recovery, economics, or operational efficiency. --- 2. Introduction Background on EOR significance and the need for optimization. Challenges in deploying EOR efficiently (uncertainty, injectant availability, mobility issues, costs). Brief introduction to the field/reservoir being studied. Research gap your work addresses (e.g., lack of integrated optimization workflow). Study objectives and paper organization. --- 3. Field Description / Case Study Background 3.1 Geological Setting Reservoir type, depositional environment, structure, heterogeneity. 3.2 Petrophysical and Fluid Properties Porosity, permeability, saturation, oil viscosity, API gravity, PVT data. 3.3 Reservoir Status Primary/secondary production history. Current recovery factor. Existing injection/production patterns. 3.4 Challenges and Constraints Technical (injectivity, low sweep efficiency, high WCT, etc.) Operational (facilities, water/steam/CO₂ availability). Environmental/economic limitations. --- 4. EOR Method Description 4.1 Selected EOR Technique Chemical/polymer/ASP, thermal (steam, SAGD), gas (miscible CO₂, nitrogen), or hybrid. 4.2 Mechanisms Why this method suits the field. Key physical or chemical mechanisms (IFT reduction, viscosity control, miscibility, wettability alteration). 4.3 Laboratory or Pilot Data (if applicable) Coreflood results. Screening assessments. Fluid–rock compatibility tests. --- 5. Optimization Methodology 5.1 Workflow Overview Flowchart of the optimization cycle (screening → model calibration → simulation → optimization → sensitivity → results). 5.2 Reservoir Simulation Model Static and dynamic model details. Model calibration and history matching. Grid resolution and boundary conditions. 5.3 Optimization Parameters Injection rate/pressure, slug size, concentration, WAG ratio, mobility ratio targets, pattern design, etc. 5.4 Optimization Algorithms Used Gradient-based, genetic algorithms, PSO, machine learning, proxy models (RSM, ANN, kriging). Justification for the chosen technique. 5.5 Uncertainty and Sensitivity Analysis Key uncertain variables (permeability distribution, relative permeability curves, adsorptive loss, miscibility pressure). Methods: Monte Carlo, tornado charts, experimental design. --- 6. Results and Discussion 6.1 Optimization Results Optimal injection schedule, slug size, timing, pattern arrangement. Impacts on oil recovery, pressure behavior, sweep patterns. 6.2 Performance Comparison Base case vs. optimized case (tables, figures). Recovery factor increase (%). Reduction in chemical usage, steam-oil ratio (SOR), or CO₂ intensity. 6.3 Economic Evaluation NPV, IRR, payout time. Sensitivity to oil price and OPEX/CAPEX. 6.4 Operational Feasibility Injectivity limits, facility modifications, pilot-to-field scale concerns. 6.5 Discussion Interpretation of results. Why optimization improves performance. Lessons learned and field implications. --- 7. Conclusions Summarize major findings of the optimization work. Degree of improvement (technical + economic). Recommendations for field implementation. Limitations and needs for further pilot testing. --- 8. Recommendations for Future Work Advanced optimization methods (AI, digital twins). Improved data gathering (4D seismic, tracer tests). Field monitoring approaches. 10. References Follow SPE/APA/IEEE style. Include both classical EOR optimization references and recent studies. ممنون میشم فقط سریع خبر بدین 🙏 اینم مقالات سلام وقتتون بخیر
