Petroliferous basin in the rock thermal conductivity and thermal conductivity research
Quartztes and rock salt have the highest conductivities.
Limiting the extraction of great amount of heat from the underground even more is the low thermal conductivity and low thermal diffusivity of rocks.
The differences between the conductivities of different kind of rocks are rather small.
Quite often it is found that in an apparently uniform piece of rock the thermal conductivity differs from centimetre to centimetre.
The heat production in rocks due to radioactivity is highest in the acid rocks and lowest in the ultra-basic rocks.
The greatest dependence upon temperature is shown by rocks with high conductivities at room temperature e. g. salt.

The reservoir rock can be of various lithological compositions.
A fossilized material in shale and other sedimentary rock that yields oil upon heating.
Geothermal energy is derived from hot water or steam created by hot or melted rock.
The results are 1) thermal expansion, and 2) thermal conductivity.
Conductivities measured at room temperatures must be corrected if they are to be used for rocks at depths greater than about 1000m.
Another problem in the determination of a good representative value of the conductivity for a given rock type arises from the heterogeneity of the material.
