Twelve-month drilling permits, spuds and first production, the DUC-proxy backlog, permit-to-spud cycle times and Wyoming counties ranked by activity momentum. Each figure is a count, percentile or index Buckhead Energy computes from grouped records; no individual well is listed.
Last computed: 2026-11-01
Quick answer: Over the last 12 months Wyoming recorded at least 673 drilling permits, 322 spuds and 204 wells reaching first production, by Buckhead Energy’s count; 569 wells sit in the DUC proxy with a median of 341 days since spud. Converse County ranks first by activity momentum score (163). Monthly counts under 3 are withheld, so totals are floors.
In the last 12 complete months: at least 673 drilling permits, 322 spuds and 204 wells reaching first production. Each total adds published monthly counts, so it is a floor.
569 wells were spudded in the last three years with no first production reported yet. This DUC proxy includes dry holes, injection wells and reporting lag, so it is not a completion queue.
The median permit 6 to 36 months old reached spud in 67 days, and the median spud 12 to 36 months old reached first production in 168 days.
It multiplies the change in a county’s permits by the change in its oil and gas production, comparing the last 12 months with the 12 before, and scales the result so 100 means both held level. It describes activity trends, not value.
Ranked by momentum score: the change in drilling permits times the change in county oil and gas production, last 12 months against the 12 before. 100 means both held level. Counties without enough published data in both windows are not scored.
| County | Momentum | Permits change | Production change |
|---|---|---|---|
| Converse | 163 | +65% | -1% |
Permit to spud uses permits 6–36 months old; spud to first production uses spuds 12–36 months old. Percentiles resting on fewer than 5 wells show n<5.

Buckhead Energy computes every figure on this page from grouped records in public oil and gas data. The page shows counts, sums, percentiles and indexes only; it does not list individual wells, leases or permits.
Counts under 3 wells and percentiles under 5 wells are withheld; totals are floors.
12-month totals add only the monthly figures that were published, so they are floors, not exact counts.
DUC here is a proxy: a well spudded in the last three years with no first production reported yet. It includes dry holes, injection wells and reporting lag, and does not establish completion status.
Cycle-time cohorts: permit-to-spud uses permits 6–36 months old; spud-to-first-production uses spuds 12–36 months old.
Momentum = 100 × (permits, last 12 months ÷ prior 12 months) × (county oil-and-gas production, last 12 months ÷ prior 12 months). 100 means both held level.
