Formation temperature for a given gradient
Input(s)
\(T_{s}\): Temperature Near Surface \(\left(\right.\) degree \(\left.{ }^{\circ} \mathrm{F}\right)\)
D: Total Depth \((\mathrm{ft})\)
\(g_{G}\): Geothermal Gradient (degree \(\left.{ }^{\circ} \mathrm{F} / 100 \mathrm{ft}\right)\)
Output(s)
\(T_{f}\): Formation Temperature (degree \({ }^{\circ} \mathrm{F}\) )
Formula(s)
\[
T_{f}=T_{s}+g_{G} *\left(\frac{D}{100}\right)
\]
