II.IX Key technical formulas (directional control, positioning, hydraulics)
- Dogleg Severity (minimum curvature):
\( \text{DLS} = \frac{\cos^{-1}\!\Big(\cos I_1 \cos I_2 + \sin I_1 \sin I_2 \cos \Delta A\Big)}{\Delta MD} \times \frac{180}{\pi} \times 100 \quad [^\circ/100\,\text{ft}] \)
- Ratio Factor (minimum curvature):
\( \text{RF} = \begin{cases} \dfrac{2}{\theta} \tan\left(\dfrac{\theta}{2}\right), & \theta \neq 0 \\ 1, & \theta \approx 0 \end{cases} \quad \text{where } \theta = \cos^{-1}\!\Big(\cos I_1 \cos I_2 + \sin I_1 \sin I_2 \cos \Delta A\Big) \)
- Coordinate increments (min curvature):
\( \Delta N = \dfrac{\Delta MD}{2} \, \big(\sin I_1 \cos A_1 + \sin I_2 \cos A_2\big)\, \text{RF} \)
\( \Delta E = \dfrac{\Delta MD}{2} \, \big(\sin I_1 \sin A_1 + \sin I_2 \sin A_2\big)\, \text{RF} \)
\( \Delta TVD = \dfrac{\Delta MD}{2} \, \big(\cos I_1 + \cos I_2\big)\, \text{RF} \)
- Build and Turn Rates:
\( \text{BR} = \dfrac{\Delta I}{\Delta MD} \times 100 \quad [^\circ/100\,\text{ft}], \quad \text{TR} = \dfrac{\Delta A}{\Delta MD} \times 100 \quad [^\circ/100\,\text{ft}] \)
- Motor toolface for required curvature:
\( \text{TF} = \tan^{-1}\!\left(\dfrac{\text{TR}}{\text{BR}}\right), \quad \text{Required BUR} = \sqrt{\text{BR}^2 + \text{TR}^2} \)
- Hydraulics – Equivalent Circulating Density (ppg):
\( \text{ECD} = MW + \dfrac{\Delta P_{\text{ann}}}{0.052 \times TVD} \)
- Bit Hydraulics (US oilfield units):
\( \text{HHP} = \dfrac{\Delta P_{\text{bit}} \times Q}{1714} \) and approximate jet impact force \( \text{JIF} \propto \sqrt{Q \times \Delta P_{\text{bit}}} \)
- Torque & Drag – Hookload (on bottom):
\( HL_{\text{on}} = W_{\text{buoyant}} - WOB - F_{\text{drag}} \quad ; \quad HL_{\text{off}} = W_{\text{buoyant}} \pm F_{\text{drag}} \)
- Anti-Collision – Separation Factor (conceptual):
\( \text{SF} = \dfrac{\text{Center-to-center separation}}{\text{Combined positional uncertainty (RMS)}} \quad ; \quad \text{Target} \ge 1.0\text{–}1.5 \text{ by operator policy} \)
