Drilling ton miles - While making short trip ton miles
Input(s)
\(\mathrm{T}_{6}\): Ton Miles for One Round Trip-at the Deeper Depth, the Depth of the Bit Before Starting Short Trip (ton miles)
\(\mathrm{T}_{5}\): Ton-miles for One Round Trip-at Shallower Depth,the Depth that the Bit is Pulled up to (ton miles)
Output(s)
\(\mathrm{T}_{\mathrm{ST}}\): Short Trip Ton Miles (ton miles)
Formula(s)
\[
\mathrm{T}_{\mathrm{ST}}=\left(\mathrm{T}_{6}-\mathrm{T}_{5}\right)
\]
