As global exploration moves into harsher environments and remote places, finding new oil and its production gets more difficult and expensive. In the existing oil fields, as production rates are declining, improving recovery factor is becoming increasingly more important. Many of these reservoirs are approaching the end of their waterflood life and are good candidates for EOR. Enhanced Oil Recovery refers to a diverse set of technologies and methods that have the potential to significantly oil increase recovery factor beyond what can be achieved by conventional water injection.

The objective of this comprehensive 5-day training course is to discuss the fundamental mechanisms, applications, and the technical issues associated with the various EOR methods. The main focus of the course will be on recent developments and new insights into EOR by low salinity water injection, gas and CO2 injection, water-alternating-gas (WAG) injection, and EOR by foam injection. The course will also cover the main properties of hydrocarbon reservoir rocks and fluids, main drive mechanisms in oil reservoirs and the reasons for the low recovery factor observed in majority of oil reservoirs.

EOR main challenges and opportunities will be discussed from the global and regional perspectives. The proper design and interpretation of the experiments required for obtaining the data needed for the numerical simulation of EOR projects will be presented. Some shortcomings of the current models and formulations will be discussed. New methodologies will be presented for improving prediction of reservoir performance under EOR.

Participants of the course will also visit the state-of-the-art EOR laboratories within the Centre for Enhanced Oil Recovery and CO2 Solutions of Heriot-Watt University and will have a unique opportunity to see what sort of experiments and measurements are needed for designing an EOR process.
