12 blueprints
Classic Decline Models
Arps exponential, hyperbolic and harmonic decline, plus the modified hyperbolic terminal-decline variant.
2 blueprintsUnconventional Decline Models
Transient hyperbolic, power law and stretched exponential, Duong, logistic growth and Ansah-Knowles-Buba.
1 blueprintDecline Diagnostics
Loss-ratio derivatives and D(t) functions for identifying the governing decline model.
1 blueprintDecline Rate Conversions
Nominal, effective and secant decline rate conversions.
1 blueprintProduction Data Quality
Outlier and downtime screening before a decline fit.
1 blueprintField Production Profiles
Aggregated field-level production and schedule profiles.
2 blueprintsDCA Auto-Fit Model Comparison
Auto-fit Arps hyperbolic and Duong decline models to the same production data, then compare R² and EUR to select the best model. Arps works well for conventional reservoirs; Duong is better for unconventional (tight/shale) with linear flow.
EUR Calculator
Calculate Estimated Ultimate Recovery (EUR) for different economic limits and decline parameters. Essential for reserves estimation and economic analysis.
EUR Sensitivity Analysis
Sensitivity analysis of Estimated Ultimate Recovery (EUR) to Arps decline parameters. Understanding parameter uncertainty impact on EUR is critical for reserves estimation and economic analysis.
Decline Model Comparison
Compare multiple decline curve models for the same well. Different models may be more appropriate depending on reservoir type and flow regime. Arps is standard for conventional, Duong for unconventional transient, and PLE for tight/shale.
