Synonym: Geothermal Temperature Profile = Geotherma

Natural subsurface temperature profile along the True Vertical Direction: $//<![CDATA[ \begin{array}{l}T_G(z)\end{array} //]]>$, where $//<![CDATA[ \begin{array}{l}z\end{array} //]]>$ is True Vertical Depth Sub-Sea (TVDss).

It is essentially a true vertical component of local Geothermal Temperature Field  $//<![CDATA[ \begin{array}{l}T_G(x, \, y, \, z)\end{array} //]]>$.

Many subsurface studies are focused on Sedimentary Cover below a specific surface area where lateral $//<![CDATA[ \begin{array}{l}\{ x, \, y \}\end{array} //]]>$ variation of Geothermal Temperature Field  $//<![CDATA[ \begin{array}{l}T_G(x, \, y, \, z)\end{array} //]]>$ maybe insignificant comparing to variation along the true vertical direction  $//<![CDATA[ \begin{array}{l}\{ z \}\end{array} //]]>$.

This happens, for example, at the lateral scales of a typical Petroleum Field and allows modelling Geothermal Temperature Field with a laterally constant Geothermal Temperature Profile  $//<![CDATA[ \begin{array}{l}T_G(z)\end{array} //]]>$.
