Shale wells often range 500–1,500 BOE/d at first production. Conventional wells are typically lower and longer-lived.
20%65%85%
Tight-oil and shale wells frequently start at 50–80% annual decline. Conventional wells may start at 15–35%.
0 (exponential)1.11.5
Shale wells typically use b = 1.0–1.5. Conventional wells are often modeled at b = 0.3–0.8.

Most operators use 4–8% as a terminal decline assumption. The switch typically occurs 5–15 years into the well's life.
