Prediction Approach for Petrothermal Properties in Al Hashimiyya Basalts-Jordan
Thermal conductivity and mineral composition of flood basalt in Al Hashimiyya city were correlated. Representative thin sections were optically analyzed for their mineral constituents and micro fractures. Findings of this
study will contribute to a comprehensive understanding of the correlation
between selected petrological characteristics of basalts and their heat conduction properties. It found that a 10% increase of opaque and ferromagnesian
minerals volume in the studied basalts leads to a thermal conductivity increasing by 0.4 W?m?1
?K?1
. This may considerably contribute to provide an
alternative to direct measurements of the thermal conductivity in Jordan basalts if a sufficient mineralogical data set is achievable. Thus, the prediction of
thermal conductivity through modal mineral composition may become a significant feature for efficient geothermal system exploration in basaltic rocks.
The results can be brought together into a petrophysical and hydrogeothermal model for better reservoir characterization. Such models will improve the
assessment of the basalt?s suitability as a geothermal reservoir for cooling and
heating utilizations.
