Pressure Required to Break Circulation
Pressure Required to Break Circulation - Annular formula |
||
| \( P_{gs} \;=\; [\; y \;/\; 300 \; ( D_h - D_d ) \;] \; L \) | ||
| Symbol | English | Metric |
| \( P_{gs} \) = Pressure to Overcome Mud's Gel Strength Inside Annulus (psi) | \(lbf\;/\;ft^2\) | - |
| \( y \) = Gel Strength of Drilling Fluid | \(lbf\;/\;100\;ft^2\) | - |
| \( L \) = Drill String Length | \(ft\) | - |
| \( D_h \) = Diameter of Hole | \(in\) | - |
| \( D_p \) = Diameter of Drill Pipe | \(in\) | - |
