There are a lot of multiphase flow correlations available in oil industry worldwide, but many times these correlations do not match with the real measured pressure data, consequently we need to get out the best correlation for this data which is give us the representative or reliable results close to measured data with the least error as possible as we can.
In our study we took well X-1; from Nakhla Field as a case study. Six production tests were used to estimate well productivity index at different time and flowing pressure survey were collected and analyzed by using Microsoft Excel and PROSPER software in order to calculate and plot the pressure gradient and to compare the results obtained by different methods with the actual one to find the best method that gives us the less value of error comparing with actual one used for construct IPR-VLP performance and make prediction for future performance by using sensitivity analysis for different reservoir pressure and gas oil ratio (GOR).
Based on this study, some of the multiphase correlations given acceptable results if compared with actual data measured ones, but didn’t have any solution in nodal analysis as in case of Mukherjee Brill correlation, and some of them given low value of error but there results and behavior in the nodal analysis not acceptable as in case of Beggs and Brill correlation.
