Abstract
Existing models for performing Nodal Analysis for a production system without displaying charts, has
been identified to be somewhat complex and can only be solved by empirical methods. However, in
this study, a simplified sub-model (Rotimi and Wilfred model) was developed from an existing complex
model (Guo-Ghalambor). In the course of simplifying the complex Guo-Ghalambor model, it was first
solved analytically using differential calculus to obtain a sub-model so that an iteration method such
as Newton Raphson coupled with advanced computer programming used to arrive at a definite
solution. With the use of a computer model, NODARES, nodal analysis was conducted for a range of
data points. The results obtained from the tool revealed that, convergence is fast on the part of using
the Rotimi and Wilfred model to perform nodal analysis. The developed computer model was validated
using a range of data points in the determination of the operating pressure and flow rate at which the
crude oil will be produced. Also, a comparative analysis between Excel Solver and the developed
computer model proved that NODARES is most suitable to perform nodal analysis without displaying
charts. Moreover, for visual representation, Poettmann Carpenter model was also used to perform
nodal analysis.
