Natural subsurface temperature distribution 
, where  is position vector.

It is formed by the upward vertical heat conduction from Earth's centre towards Earth's surface with account of subsurface rock inhomogeneity, local immovable heat sources and lateral/vertical heat-mass flows.


In Basin Analysis scales the Geothermal Temperature Field can be quite complex, while at a scales of a typical Petroleum Field it usually simplifies to a laterally constant Geothermal Temperature Profile.
