Wellsite

Decline Curve Analysis

Fit an Arps decline to monthly production and forecast it to the economic limit — EUR and remaining reserves, with every assumption on the table. Pull a well from the data cloud or bring your own numbers.

Well

Fit a decline, get EUR and remaining reserves

  1. Pick a well from the data cloud — its monthly production loads automatically — or paste your own.
  2. The Wellsite decline engine fits an Arps curve (hyperbolic, b clamped 0–2) anchored at the peak month.
  3. Refine it: fit window, economic limit, or the parameters themselves. Results update live.
  4. Save or export the forecast — other Wellsite apps reuse it instead of re-fitting.

Every number is computed by a deterministic engine and shows its derivation — no black boxes.
