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.
Productivity Index Calculation
Calculate well productivity index (PI) and understand the impact of skin damage. Also shows drainage radius and effective wellbore radius calculations.
