With growing demand on energy, there is increasing need to maximise the production of oil and gas, especially from depleting reservoirs. This course examines the methods and processes of enhanced recovery of oil and gas and provides students with the knowledge and understanding required to develop, acquire and safely integrate enhanced oil recovery technologies into field development plan and field operations.
|Session||Second Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
This course examines different hydrocarbon recovery methods. Secondary recovery is revisited, and tertiary recovery methods are explored in greater detail. The properties of injected and reservoir fluids are discussed. Fluid flow in porous media is revised, considering the rock-fluids interactions under different injection strategies and reservoir conditions. Concepts of electrolyte solutions, geochemistry and surface chemistry and their application to enhanced oil recovery (EOR) are discussed. Detailed analysis of the different EOR methods is presented, including the mechanisms of hydrocarbon displacement and design of associated facilities and technology for field implementation of the method. An awareness of the laboratory assessment of the effectiveness and environmental impact of each EOR method is provided. The recovery of heavy oils is discussed. Throughout the course, examples will be drawn from real life case studies.
This is the total time spent in lectures, tutorials and other class teaching.
One three-hour written examination (80%) and continuous assessment (20%).
The re-sit will comprise of re-doing the failed element/s (exam and/or coursework assessment/s) from the 1st attempt with a maximum CGS mark of D3. The marks for other elements (successfully passed) will be carried over. Resit mark of either RP or RF will be recorded.
