Objective:

This advanced level course is aimed at experienced production engineers seeking an update to the new methodologies available for maximizing production from oil fields under artificial lift. A familiarity with conventional nodal analysis methods and design techniques for gas lift and electrical submersible pump systems will be assumed. The course will include the sequential linear programming method as implemented in the ReO^® software package.

Course Description:

The course is based on case studies of actual field optimization and is aimed at allowing engineers to realize the typical target of 5-10% increase in production rate usually achievable by constructing and optimizing a ReO production model.
