EOR Polymer Flooding - Lessons Learnt from Field Applications (PRO15)
Description
Polymer flooding has been recognised as an effective Enhanced Oil Recovery (EOR) method for many years. This course is focused on the realisation of a polymer field project and will discuss different failures and successful field projects worldwide in detail.
The course covers a review of the basic principles of polymer flooding, description of water soluble polymers, screening procedures and other lab tests for product quality, retention/adsorption control and polymer selection. Other features include microbial and oxygen impact on field applications as well as mixing with produced water, injection control and surveillance guidelines for the whole project. Several international field projects including their current status will also be highlighted.
Course Level: Advanced
Duration: 5 days
Instructor: Wolfram Kleinitz
