Since Enhanced/ Improved Oil Recovery (EOR/ IOR) schemes in a given reservoir involve significant financial risks due to various uncertainties, it is prudent to ‘pilot’ them in a small, representative portion of the property.
It is well known that primary and secondary production schemes in fields containing heavy oil (< 20 °API) generally result in recoverable reserves of 15% or less. Reserves additions via new discoveries have been declining steadily in the last decades, and the increase of recovery factors from mature oilfields in known basins will be critical to meeting growing market demand.
Primary and secondary production schemes generally result in recoverable reserves in the range of 25 to 45%. Meeting the recovery target forecast at the time of project development requires the implementation of a reservoir management plan that includes project surveillance at all levels (well, pattern, area, and field), both surface and subsurface.
This course will emphasize critical considerations during enhanced oil recovery (EOR) screening and pilot design. Discussions will include monitoring and surveillance, and EOR project implementation. Appropriate case studies and exercises will be used to illustrate various concepts.
