| Abstract |
Tracer flow testing trials have been conducted in Indonesia to assess the accuracy of the isopropanol (IPA) tracer flow testing procedure. Flow measurements from production wells were compared with physical measurements and alternative tracer flow measurements (SF6). The testing was conducted with production well flowrates in the range 25-110 kg/s and enthalpies in the range 1350 - 2800 kJ/kg. Results are presented for tests conducted between 2001-2003. The mean difference in steam flows for IPA and SF6 tracer testing was about 6%, with no systematic bias. For dry steam wells, the difference between IPA flows and orifice plate measurements was a mean 1.2% for 12 tests. The results confirm that IPA tracer flow testing is a viable method over a wide range of operating conditions. |
