Bottomhole pressure in a static geothermal well
Input(s)
\(\rho\): Density \(\left(\mathrm{lb} / \mathrm{ft}^{3}\right)\)
D: Vertical Depth (ft)
\(g\): Acceleration of Gravity \(\left(\mathrm{m} / \mathrm{s}^{2}\right)\)
\(g_{c}\): Units Conversion Factor \(\left(\mathrm{m} / \mathrm{s}^{2}\right)\)
Output(s)
\(\frac{d p}{d D}\): Bottomhole Pressure in a Static Well \((\mathrm{psi} / \mathrm{ft})\)
Formula(s)
\[
\frac{\mathrm{dp}}{\mathrm{dD}}=\frac{\rho}{144} \cdot \frac{\mathrm{g}}{\mathrm{g}_{\mathrm{c}}}
\]
