Enhanced Oil Recovery (EOR)

Details :

One-third to one-half of the original oil-in-place may remain in a reservoir as it reaches abandonment due to its economic limit. The primary reasons are: heterogeneity of the reservoir, unfavourable fluid properties, inefficient nature of the displacement process, oil price, and production cost considerations. The secondary reasons, however, are: inappropriate development, inefficient reservoir management practices, and escalating costs of remedial interventions/corrective measures and producing operations. The oil recovery is generally lower than expected due to some combination of the above reasons. Gaining a better understanding of the reservoir fundamentals and the important variables that influence the recovery process can enhance it.

This course aims to provide such an understanding. It presents the subject material with a clear focus on: developing and producing the reservoir efficiently within its complexity constraints, harnessing energies available within the reservoir-aquifer-injection system, realising technical benefits and application limitations of the various EOR methods, and selecting the optimum time window. This course covers the recovery improvement possibilities that present themselves at all stages in the reservoir life cycle. It thereby enables one to timely select the most beneficial method and set realistic expectations on production behaviour changes and recovery improvement. The impacts of the selected method on personnel training, technology transfer, and facility modification are also covered. The material is presented in simple terms that would enable a participant to understand what works where, what fails when, and why. It is light on theoretical equations, but it scrutinises these to comprehend importance of significant parameters. It utilises case studies from projects around the world; their analyses and interpretations aid the participant in understanding of the material. Many illustrative problems, worked in the class by teams, are helpful in gaining a better grasp of the subject matter.

To acquire basic theory of Enhanced Oil Recovery, analyse more common methods of EOR and learn how to carry out EOR screening.  Learn how to use Thermal, Chemical and Solvent methods: selection criteria, recovery targets and challenges, design considerations, case studies.


Upon completion of this training, participants will be able to select the enhanced recovery method that best suits the conditions of the reservoir which they operate and also maximise reservoir recovery at the least cost, ensuring maximum investment efficiency. Technical challenges of enhanced oil recovery phase; increasing complexity, cost/benefit consideration, facilities modifications and personnel training will be discussed. A critical review of the emerging technologies, future R & D directions will be devoted an extensive coverage. Participants will learn to forecast reservoir performance under various EOR methods employing the proper empirical, analytical, and simulation tools
