Field Production Profile

Description

Field-level production forecasting using buildup-plateau-decline model. Models the complete production lifecycle: ramp-up to plateau, sustained plateau production, and Arps decline phase.

Parameters:

  • t_buildup: Time from first production to reach plateau rate (ramp-up period)
  • t_plateau: Duration of plateau period at constant rate
  • Q_plateau: Target plateau production rate
  • Di: Initial decline rate after plateau ends
  • b: Arps b-factor (0=exponential, 0.5=hyperbolic, 1=harmonic)

Required Functions

PO.FPP.Field.Rate

Calculates field production rate at time t using buildup-plateau-decline model. Linear ramp during buildup, constant rate during plateau, Arps decline after. Supports exponential (b=0), hyperbolic (0<b<1), and harmonic (b=1) decline.

PO.FPP.Field.Prod

Calculates cumulative field production at time t using buildup-plateau-decline model. Integrates rate over buildup, plateau, and decline phases. Supports exponential (b=0), hyperbolic (0<b<1), and harmonic (b=1) decline.

Related Blueprints

Multi-Well Schedule Aggregation

Aggregated field production from a multi-well drilling schedule. Uses convolution of a typical well decline profile with a well drilling schedule to forecast total field production over time.

Arps Decline Forecast

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

Gas Reservoir Production Forecast

Forecast gas reservoir pressure and production using material balance equations. Given OGIP, predict pressure at future production levels or vice versa.

Duong Decline Forecast

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.

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.

EUR Calculator

Calculate Estimated Ultimate Recovery (EUR) for different economic limits and decline parameters. Essential for reserves estimation and economic analysis.
