How this works

Type curve: Each well follows the same Arps hyperbolic decline: q(t) = qi/(1+b*Di*t)^(1/b).

Well scheduling: Initial wells start in month 1. Additional wells are added at the start of each subsequent development year.

Field profile: Sum of all individual well rates at each month.

EUR: Cumulative production across all wells until economic limit.
