Journal Article: Three New Improved Na-K Geothermometers Using Computational And Geochemiometrical Tools- Application To The Temperature Prediction Of Geothermal Systems

Abstract
Three new improved equations of the Na/K geothermometer were developed through computational (artificial neural networks) and statistical tools (based on ordinary linear regression) from the analysis of a more representative world geochemical database (n=212) than hitherto used. The new Na/K geothermometers are given by. the following equations: These new geothermometric equations were successfully evaluated and compared with measured deep temperature wellbore logs using a different geochemical database (n=112) to avoid the training and regression bias. The obtained results clearly show that the new geothermometers systematically, provide better and reliable estimations of the deep equilibrium temperatures (for temperatures over 160 degrees C) than the equations previously reported in the geothermal literature. Details of the theoretical basis of the Na/K geothermometer: the computational and geochemometric methodologies used, as well as the validation and comparison results are outlined in this work.
