Nodal Analysis

Program Objectives


This introductory course deals with production engineering issues from the perspective of reservoir management process. Specifically, it is to enhance and optimize well production rate in some comprehensive manner. To do so, the whole well production system is analyzed using nodal analysis. The course first introduces both production and reservoir engineering issues to help the students understand well inflow performance better. In quantifying the reservoir and well interactions, it also brings in basic pressure transient analysis. Then, it considers the well outflow performance relationships. Here artificial lift methods are also considered: primarily, gas lift and electric submerged pumps (ESP). The resulting well production system is composed of the inflow part and the outflow part modified by the artificial lift method used, and the nodal analysis method is used to analyze the total system performance.
