Results of a comparative analysis between measured (BHTm) and temperature estimates calculated for the new gas geothermometers (BHTGaS_GeoT). The plots a–d show the temperature results predicted by the new geothermometers for LIQDR wells, whereas the plots e–h] show the results for VAPDR. n* is the number of samples that fulfil the applicability conditions of each new gas geothermometer (Table 8). Dotted and dashed lines represent a hypothetical variability of the ± 10% and ± 20% with respect to the BHT mean value, respectively
