Volumes and Strokes
Volumes and Strokes - Annular Volume formula |
||
| \( DS_v \;=\; (DS_{id}^2 \;/\; 1029.4 ) \; PL \) | ||
| Symbol | English | Metric |
| \( AC \) = annular volume | \(bbl\) | - |
| \( D_h \) = drill hole diameter | \(in\) | - |
| \( D_{pod} \) = drill pipe OD | \(ft\) | - |
Volumes and Strokes - Drill String Volume formula |
||
| \( DS_v \;=\; (DS_{id}^2 \;/\; 1029.4 ) \; PL \) | ||
| Symbol | English | Metric |
| \( DS_v \) = drill string volume | \(bbl\) | - |
| \( DS_{id} \) = drill string ID | \(in\) | - |
| \( PL \) = pipe length | \(ft\) | - |
Volumes and Strokes - Total Strokes formula |
||
| \( S \;=\; DS_v + AC \;/\; P_o \) | ||
| Symbol | English | Metric |
| \( S \) = total strokes | \(dimensionless\) | - |
| \( DS_v \) = drill string volume | \(bbl\) | - |
| \( AC \) = annular volume | \(bbl\) | - |
| \( P_o \) = pump output | \(bbl\;/\;stroke\) | - |
