Thanks John....it's an interesting coincidence that we were just given the temperature formula we were looking for the other day :)

"While in most places in the world, the geothermal gradient is 3 Celsius per 100 meter, here in Hungary on the average 5-7 Celsius."

So since the Szolnok is from 3425m to 4388m (in the Mako-6), we can expect the temperatures to be from 171 to 307 celcius (339-584 F)

That fits the standard HP/HT right up to the Extreme HP/HT categories.

The Elgin-Franklin HP/HT wells in the North Sea are around 392 F, so that sort of puts things into perspective.
