Fetkovich IPR Curve
Construct an IPR curve using the Fetkovich backpressure equation. This empirical method works for both single-phase and two-phase flow by fitting well test data to Qo = C(Pr² - Pwf²)ⁿ.
Flow Regime Comparison
Compare well productivity under different flow regimes: pseudosteady state (bounded reservoir), steady state (constant pressure boundary), and transient (infinite-acting). Understanding flow regime impacts is essential for accurate production forecasting.
Gas Well Deliverability
Gas well deliverability analysis comparing Darcy flow (low rate) with non-Darcy flow that includes turbulence effects at high rates. The non-Darcy coefficient D accounts for inertial resistance near the wellbore.
Horizontal Well PI Comparison
Compare horizontal well productivity index calculations using different correlations. Useful for understanding the sensitivity of PI estimates to the chosen method.
Klins-Clark Modified Vogel IPR
Construct an IPR curve using the Klins-Clark (1993) modified Vogel equation. This correlation improves on the original Vogel method by introducing a pressure-dependent exponent d that accounts for the ratio of reservoir pressure to bubble point pressure.
Productivity Index Calculation
Calculate well productivity index (PI) and understand the impact of skin damage. Also shows drainage radius and effective wellbore radius calculations.
Vogel IPR Curve
Construct an IPR curve using the Vogel correlation for solution-gas-drive reservoirs producing below bubble point. Shows the characteristic concave-downward shape of two-phase flow.
