Comparison of measured and simulated pressure and temperature profiles in geothermal wells

The correct application of geothermal wellbore flow simulators is a useful tool since their adequate calibration and use often avoids the need to perform costly experimental PTQ logs inside geothermal wells. Two existing wellbore flow simulators, GEOPOZO and WELFLO, were used to obtain pressure and temperature profiles and the results were compared with experimentally measured PT logs in well Az-19 from the Los Azufres, Mexico, geothermal field. PT logs were run using high-precision electronic logging equipment. Comparison of experimentally measured and computed PT profiles shows a maximum error of 3.2% for the pressure profile obtained with the WELFLO simulator
