DESCRIPTION
Training Enhanced Oil Recovery (EOR) – Oil recovery operations traditionally have been subdivided into three stages: primary, secondary and tertiary. These stages described the production from a reservoir in a chronological sense. Primary production resulted from the displacement energy naturally existing in reservoir. Secondary recovery usually implemented after primary production declined, the term secondary recovery is now almost synonimous with waterflooding. Tertiary recovery was that obtained after waterflooding (or whatever secondary process used) it’s used miscible gases, chemicals and or thermal energy to displace additional oil. When the waterflooding stage might be reasonably be bypassed the term tertiary recovery fell into disfavor in petroleum engineering term and the designation of enhaced oil recovery (EOR) become accepted to replace the term of secondary and tertiary recovery.
In describing the different EOR processes (Waterflooding, Miscible Displacement, Chemical Flooding: Micellar Polymer, Surfactant, Alkaline and finally Thermal Recovery Processes, it will be focused on the fundamental concepts of each processes and it will also present methods of predicting oil recovery when the processes are applied to oil reservoir. Many methods are available to calculate displacement performance, ranging from simple models based on volumetric sweep to sophisticated method. Thus, with the proper understanding of all enhanced oil recovery processes will reduce the entire cost of the plant and production operation of EOR system.
