Duong Decline Forecast

Description

Decline curve forecast using the Duong model, specifically designed for unconventional reservoirs exhibiting transient linear flow. The Duong model captures the power-law behavior common in tight oil and shale gas wells.

Parameters:

  • qi: Initial production rate
  • a: Decline constant (typically 1.0-2.0)
  • m: Decline exponent (typically 1.0-1.5)
  • q_inf: Infinite time rate (often set to 0)

Decline curve analysis using the Arps hyperbolic decline equation. Calculates rate and cumulative production over time for production forecasting.

Decline Diagnostics Analysis

Diagnostic analysis for decline curve interpretation using derivative-based methods. These tools help identify flow regimes and validate decline model selection.

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.

Decline Rate Conversions

Convert between different decline rate representations. Understanding the difference between nominal and effective decline rates, and between different time bases, is essential for consistent decline analysis.
