| Abstract | An empirical graphical method, based on type curve matching is presented. Using only flowing pressure temperature surveys, the flowing enthalpy vs depth in two phase wellbores can be determined. Also fluid entries are identified in the two phase as well as the single phase region. In some cases the relative flow rates of each entry and the enthalpy of the entry itself can be determined. Six example surveys from the Coso field are given and interpreted. |
