Chemical geothermometers are used to estimate geothermal reservior temperatures. However, there are many different geothermometry methods that give identical temperature estimates in some cases but very different results in many other cases.
For the evaluation of reservoir temperature number of geochemical and gas thermometers are in practice. Each thermometer has some limitations and assumptions. However Na-K-Ca and SiO2 ( quartz and chalcedony ) evaluating good result for large number of geothermal resources in various parts of india..
As I understand there is, to my knowledge, no "best "or Universal geothermometer, you have to test different geothermometers and element relations (cations and gas) in order to find what works best on the particular reservoir you are studing.
In fact it is better to think in terms of the more adapted geothermometers; that means those which give the best correlation with the measured temperatures at the surface. However it seems that tools such as Na-K-Ca and SiO2 seem to be the most reliable in most of the sedimentary geologocal environments...
It is best to think of chemical geothermometers in terms of processes and whether these processes are relict or current; this is especially true about the cation geothermometers. In terms of current processes, several silica geothermometers may be used. More importantly, we should look at nature and deduce what's happening or what has happened before we apply what we think would be the appropriate geothermometer.
I think that the best geothermometers are SiO2, Na-K-Ca that give reliable results in sedimentary reservoirs, in my opinion "Multiple mineral equilibrium approach" is also a good way to estimate reservoir temperatures.
