Drilling ton miles - Drilling/connection ton miles
Input(s)
\(\mathrm{T}_{2}\): Ton Miles for One Round Trip-Depth Where Drilling Stopped Before Coming out of Hole (ton miles)
\(\mathrm{T}_{1}\): Ton-miles for One Round Trip-Depth Where Drilling Started (ton miles)
Output(s)
\(\mathrm{T}_{\mathrm{D}}\): Drilling/connection Ton Miles (ton miles)
Formula(s)
\[
\mathrm{T}_{\mathrm{D}}=3 *\left(\mathrm{~T}_{2}-\mathrm{T}_{1}\right)
\]
