Drilling ton miles - Setting casing ton miles
Input(s)
\(\mathrm{W}_{\mathrm{p}}\): Buoyed Weight of Casing (lb/ft)
\(\mathrm{L}_{\mathrm{cs}}\): Length of One Joint of Casing (ft)
D: Depth of the Setting (ft)
\(\mathrm{W}_{\mathrm{b}}\): Weight of Travelling Block Assembly (lb)
Output(s)
\(\mathrm{T}_{\mathrm{c}}\): Setting Casing Ton Miles (ton miles)
Formula(s)
\[
\mathrm{T}_{\mathrm{c}}=\left(\mathrm{W}_{\mathrm{p}} * \mathrm{D} *\left(\mathrm{~L}_{\mathrm{cs}}+\mathrm{D}\right)+\mathrm{D} * \mathrm{~W}_{\mathrm{b}}\right) * \frac{0.5}{5280 * 2000}
\]
