Abstract
In Part I principles of matching analysis were indicated, and it was shown that variations or discontinuities in measured downhole pressure and temperature profiles in a discharging well have to be carefully examined before proceeding with the analysis. The lower bound method was presented as an analytical tool for assessing the consistency of such measured data. In this part the relationships between CO 2, enthalpy, and secondary feed zone characteristics are determined for a case study well, Rotokawa 5 in New Zealand, to demonstrate their importance to suitably calibrating the well model. It is shown that, even where a number of reasonably accurate downhole profiles is available, it is difficult to satisfactorily calibrate the secondary feed characteristics. However, the wellbore flow performance can still be simulated with sufficient accuracy.
