Production Optimization Training

Current Course Schedule:

Objective:

The course is intended for petroleum, reservoir and production engineers and others interested in methods of increasing and/or optimizing oil recovery through analyzing and upgrading the production system by installation or upgrade of artificial lift and other means. The course deals primarily with flow modeling of the production system and thus forms a logical extension to its companion course entitled Well Inflow Optimization, although attendance at the latter is not a prerequisite.

Course Description:

The course is based on a consideration of the total production system, from reservoir to surface. A brief review of inflow performance is followed by the development of concepts of single and multiphase flow up through the production tubing. Emphasis is placed on analysis of vertical lift characteristics of producing wells by means of Nodal analysis. An important element of the course consists of artificial lift design, particularly with respect to gas lift, ESPs and jet pumps.

An introduction to multi well modeling and optimization is also included. The course contains many practical examples of production optimization and related field problems. The solution to these problems is aided by use of the interactive WellFlo suite of computer programs.
