November 2026Why the decline curve runs low: wells that bounce back

About 35 to 50% of wells recover after the training window. A low month just before the forecast multiplies the typical miss by two to five, but does not explain all of it.

November 2026Gas has a season. Oil mostly doesn't.

Alberta and BC gas run 6 to 10% above trend in winter and below it through summer and early autumn. Oil barely moves with the calendar.

November 2026Shut-ins and restarts: how many wells stop, and do they come back?

Of the wells producing in January 2022, 84% in Alberta, 82% in Saskatchewan and 73% in BC were still producing in September 2026; about one well in ten had a gap of three months or more.

November 2026Are new wells getting better? First-six-month rates by year

Alberta gas wells that first produced in 2025 started 19% stronger than 2022 starters at the median; Saskatchewan oil wells were roughly unchanged.

November 2026Gas-oil ratios: an "oil well" is not the same everywhere

Alberta crude-oil wells have a median gas-oil ratio of about 1,896 scf/bbl, Saskatchewan about 693, and Alberta bitumen wells about 352.

November 2026What a naive load gets wrong: traps in Canadian well files

Default CSV loading drops leading zeros from codes, counts 13,735 extra Alberta well rows, and splits licence statuses into 16 spellings instead of 8.

A backtest of a bounded Arps decline curve on about 1,900 Alberta, Saskatchewan and BC wells: how accurate a 12-month forecast is, how much history you need, and why the curve runs low.

Monthly snapshots

One page per month with the headline rates, changes and wells producing for Alberta, Saskatchewan and BC, back to January 2024. These were written in November 2026 from the files available then, so they are a retrospective catalogue, not archived releases.
