ABSTRACT
The development and commercial deployment of modern Enhanced Oil Recovery methods (EORs) is today seen as the global oil industry’s core way to improve the efficiency of initial recoverable reserves through an enhanced Oil Recovery Factor (ORF), a measure that represents the percent of the in-place oil discovered that is technically recoverable. With over a hundred various related technologies now available worldwide, the development of new solutions continues to gather steam. Primary and Secondary generations of EORs have made way for tertiary ones that are explored in this thesis. The petro-physical properties - porosity, permeability, temperature, viscosity, sand thickness - of five fields which are the Amaa Field, Bonga Field, Danna Field and Amboy Field of the Niger Delta was used for this analysis by comparing them with the SPE screening criteria properties for applying EOR. The studies exposed the technical constraint of applying EOR in oil fields present in the Niger Delta area. The limitations of each EOR method were highlighted and the best that can be applied to our fields was emphasized on. It can be seen that virtually all the wells consider were successful candidate of water flooding, hydrocarbon flooding, Nitrogen flooding and Carbon dioxide flooding. Which implies that, all those EOR processes mentioned above can be used to improve recovery processes in our Niger Delta fields.
