Decline. Diagnose. Predict.
EDS provides fast, intuitive decline curve analysis to forecast production and evaluate reservoir performance. Users can compare simulation results with standard decline models, exponential, harmonic, and hyperbolic and toggle log-scale plots for clearer trend interpretation. Both automatic and manual curve fitting are supported.
For unconventional wells, EDS includes Duong’s method to handle long transient-flow periods and improve early-to-mid-life production forecasting in low-permeability reservoirs.
EDS adds a unique capability to model reservoir boundary pressure decline using exponential, harmonic, or hyperbolic trends. This lets users simulate a single well in a system where boundary pressure drops over time mirroring true boundary-dominated flow.
The model captures late-time effects such as rising GOR when pressure falls below bubble point and increasing WOR as fluid properties shift with evolving gas saturation.
This feature provides a more realistic view of mature-well behavior and improves understanding of multiphase flow dynamics under pressure-depletion conditions.
