The purpose of the course is to introduce the fundamentals of the nodal analysis approach and its applications in modeling and optimization of the oil/gas production process. The course content includes how to obtain the inflow performance relationship, how to model the single-phase and multiphase flow in wells, how to model the single-phase and multiphase flow through restrictions, how to identify the weak components in the production system, how to improve/optimize the production system based on the nodal analysis results, and how to design artificial lift methods.
