Drilling Permit

A regulatory authorization required before drilling a new oil or gas well. In federal and many state jurisdictions, the permit is called an Application for Permit to Drill (APD). Permit filings are a leading indicator of operator activity and are publicly available from state regulatory agencies.

A drilling permit (formally an Application for Permit to Drill, or APD) is the regulatory authorization an operator must obtain before breaking ground on a new well. Permits are issued by state regulatory agencies — the Texas Railroad Commission, Colorado COGCC, New Mexico OCD, and others — after reviewing the well plan for compliance with spacing rules, environmental requirements, and technical standards.

Why Permit Data Is a Leading Indicator

Permits precede drilling by weeks to months. Because permit filings are publicly disclosed in near-real-time, they are one of the best available leading indicators of operator capital deployment and basin activity. An operator that files 40 permits in a county in a single month is signaling a significant drilling program — before a single well has been spud.

EnergyNetWatch tracks permit filings across 14+ states, allowing users to monitor operator activity before it shows up in production data.

What a Permit Record Contains

A typical drilling permit record includes:

  • API number (assigned at permit stage)
  • Operator name and license number
  • Lease or unit name
  • Proposed surface and bottom-hole location (lat/lon or survey coordinates)
  • Target formation
  • Proposed total depth
  • Permit date (filing date and approval date)

Permit to Spud Timing

The lag between permit approval and actual spud date varies. In active basins with available rig capacity, operators may spud within 30–60 days of permit approval. In slower environments, permits may sit "in the bank" for 6–18 months before drilling begins — or expire unused if commodity prices deteriorate.
