Directional drilling core formulas you’ll learn and apply

• Survey calculation (Minimum Curvature)
  • Dogleg angle: $$\beta=\cos^{-1}\!\left[\cos I_1\cos I_2+\sin I_1\sin I_2\cos(\Delta A)\right]$$
  • Dogleg severity (deg/100 ft): $$\text{DLS}=\frac{\beta\cdot180/\pi}{\Delta MD}\times100$$
  • Ratio factor: $$RF=\begin{cases}\frac{2}{\beta}\tan\left(\frac{\beta}{2}\right),&\beta\neq0\\1,&\beta=0\end{cases}$$
  • Positional increments: $$\Delta N=RF\cdot\Delta MD\cdot\frac{\sin I_1\cos A_1+\sin I_2\cos A_2}{2}$$ $$\Delta E=RF\cdot\Delta MD\cdot\frac{\sin I_1\sin A_1+\sin I_2\sin A_2}{2}$$ $$\Delta TVD=RF\cdot\Delta MD\cdot\frac{\cos I_1+\cos I_2}{2}$$
• Build/Turn rates (approximate over short interval)
  • Build rate: $$BR=\frac{I_2-I_1}{\Delta MD}\times100\ \ (\text{deg}/100\ \text{ft})$$
  • Turn rate: $$TR=\frac{A_2-A_1}{\Delta MD}\times100\ \ (\text{deg}/100\ \text{ft})$$
• Slide/Rotate blending (motor assemblies)
  • Average build: $$\overline{BR}=S\cdot BR_{\text{slide}}+(1-S)\cdot BR_{\text{rotate}}$$
  • Average turn: $$\overline{TR}=S\cdot TR_{\text{slide}}+(1-S)\cdot TR_{\text{rotate}}$$
  • Where S is slide fraction (0–1). For fixed-bend motors, typically \(BR_{\text{rotate}}\approx0\) when toolface is neutral.
• Hydraulics and ECD
  • Bit hydraulic horsepower: $$HHP=\frac{\Delta P_{\text{bit}}\cdot Q}{1714}$$
  • Equivalent circulating density: $$ECD=MW+\frac{\Delta P_{\text{ann}}}{0.052\cdot TVD}$$
  • Annular pressure loss (conceptual): $$\Delta P=f\cdot\frac{L}{D}\cdot\frac{\rho v^2}{2} \quad (\text{model selection: Bingham/Power-Law})$$
• Torque & Drag (soft-string concept)
  • Axial drag (per element): $$dF=\pm W\sin\theta+\mu W\cos\theta$$
  • Torque accumulation (per element): $$dT=\mu N r$$
  • Where \(W\) is normal weight, \(\theta\) inclination, \(\mu\) friction factor, \(r\) radius, and sign depends on tripping direction.
• Anti-collision
  • Separation factor (concept): $$SF=\frac{\text{Separation}}{\sqrt{\sigma_{well}^2+\sigma_{offset}^2}}$$
  • Maintain operator-defined SF criteria throughout curve/lateral on multi-well pads.
