Energy Secretariat data as of August 2026 (production) and July 2026 (fracs). Production records are from unconventional wells (shale and tight), which is where the Secretariat publishes the well-by-well series. Fracs with impossible per-stage values (more than 700 t of sand or 4,000 m³ of water) are discarded, as they are data-entry errors. Drilling speed is not calculated: the start and end drilling dates in the registry are not reliable for that.
