Global demand for oil continues to grow while production rates from mature oil fields continue to decline. Only two ways exist to increase the global supply of oil: find new reserves or boost recovery from existing reservoirs. The scarcity of significant discoveries and increased finding costs contribute to the urgent need for the industry to apply modern EOR techniques to their fields. The goal of EOR is to optimize long-term recovery of entire reservoirs and fields—not just to increase short-term productivity of individual wells—without expanding the environmental footprint.
Detailed reservoir characterization is the starting point for any successful EOR project. Multiscale reservoir models need to be built to understand complex reservoir systems by integrating data on all scales—pore, log, interwell, and reservoir or field scale. It is vital to characterize reservoirs with EOR in mind early in the field development planning stage to ensure success of these projects. Detailed reservoir characterization also supports more efficient decision making at every stage of the EOR workflow—from initial screening to pilot design and full-field implementation.
With the current available technologies, reservoir characterization for EOR purposes should include screening criteria related to reservoir properties, petrophysical properties, laboratory feasibility studies, geomechanics and reservoir heterogeneities as a standard EOR assessment tool. The goal of this session is to share experience in reservoir characterization and EOR techniques.

The performance prediction of enhanced oil recovery (EOR) processes, critically depend on the EOR study design and selection of most suitable EOR method/process for a particular reservoir. The recompense of reservoir simulation results and field operations data helps impart value to the success of the EOR project(s). Integrated reservoir modeling, continuous production surveillance and close well monitoring, could yield adequate optimization of EOR process designs.
Customized data analysis workflow, in this context, shall furnish full range of documents desired for operational needs. The presenter’s experiences in this session shall help unfold key steps in transforming the pertinent static and dynamic data to effectively designing, optimizing, monitoring and managing the EOR projects.

In this session, EOR projects from various parts of the world will be comprehensively discussed, from the initial appraisal stages until their status quo. Specifically, the panelists will talk about the entire life cycle of these projects covering the decision-making process pertaining to the choice of the EOR method, well construction and completion, production techniques, surface facilities, and reservoir management. A special emphasis will be put on best practices and on how the challenges faced during the project life were analysed and overcome.

The research for tomorrow's oil reserves has directed the efforts of the energy industry to frontiers beyond the conventional exploration and production strategies. These frontiers are defined not by geography or geology, but rather by technology. They are a collection of technologies that involve the use of anything to change the reservoir fluid and rock properties for producing more oil that fall under the broad umbrella called enhanced oil recovery (EOR).
The results of successful application of this new technology will have a decisive impact on the energy conservation programme of any oil producing country, but the problem is that these methods make the producing cost per barrel more than five times the normal one with no 100% guarantee for the results. That is why it needs a lot of economic analysis to determine the associated risks.
The objective of this session is to illustrate some cases for performing economic sensitivity analysis on key input variables such as oil prices, price of raw material, capital expenditures, operating expenses, and oil recovery. The aim is to develop sensitivity analysis for each variable and assess the impact of each variable on the future engineering plan and associate economically risked value of the EOR projects. Final findings could be applied to any EOR candidate reservoir worldwide.

Surface facilities are the logical result after a field development plan has been agreed for the operation of the oil and gas field. As a matter of fact, good facilities design will not only affect the technical performance of the field, but also its economical success in the long run. Most of the technical design around EOR implementation require robustness along with some flexibility, simplicity along with reliability. This is particularly important for offshore operations where the facility footprint is limited and logistics for product delivery and storage is challenging. Through knowledge sharing and case studies, this session will discuss facility design, its fit in the project planning and the facility requirements applied to EOR methods. This session will also cover environmental issues and safety drivers that represent the essence for an EOR scheme.

The majority of EOR projects are being executed on US, Canada, Venezuela, Indonesia and China. However the numbers of EOR projects in the Middle East are quite low.
Due to the decline in new oil discoveries over the last decade, it is believed that EOR techniques such as chemical, thermal, microbial and others will play an important role in helping to meet the energy demand in the future. Decisions on future EOR projects are based on economic and EOR screen criteria.
The main objective of this session is to select the best enhanced oil recovery method(s) to enhance oil recovery in the Middle East by considering new technology, the updated screen criteria, and oil prices. In addition, EOR techniques used in past and present will be evaluated.
Examples will show the role of economics in the future of CO2 capturing. Novel EOR methods are already appearing from nanotechnology developments. Successes and failures in methods of applying electric downhole heating will be summarized, and recent examples will be discussed, pointing to the importance of collaboration between petroleum engineers and other disciplines
