Core Calculations You Will Use

Master these operational formulas; they underpin alarms, lag, and trend analysis.

• Hydrostatic Pressure: $P_h\,[\text{psi}] = 0.052 \times \text{MW}\,[\text{ppg}] \times \text{TVD}\,[\text{ft}]$
• Equivalent Circulating Density (estimated): $\text{ECD}\,[\text{ppg}] = \text{MW} + \dfrac{\Delta P_{\text{ann}}\,[\text{psi}]}{0.052 \times \text{TVD}\,[\text{ft}]}$
• Annular Capacity: $C_a\,[\text{bbl/ft}] = \dfrac{\text{OD}^2 - \text{ID}^2}{1{,}029.4}$ (OD/ID in inches)
• Lag Volume: $V_{\text{ann}}\,[\text{bbl}] = \sum(C_a \times \Delta \text{Depth})$
• Lag Strokes: $\text{Strokes}_\text{lag} = \dfrac{V_{\text{ann}}\,[\text{bbl}]}{\text{Pump Output}\,[\text{bbl/stk}]}$
• Rate of Penetration: $\text{ROP}\,[\text{ft/hr}] = \dfrac{\Delta \text{Depth}}{\Delta t}$
• Gas Ratio (trip vs. background): $\text{GR} = \dfrac{G_{\text{peak}} - G_{\text{bg}}}{G_{\text{bg}}}$
• Cuttings Transport Indicator (simplified): $\text{CTI} \propto \dfrac{V_{\text{ann}} \times \mu}{\rho \times d_c}$ (trend-only; field-calibrated)
