}Frequently Asked Questions About Well Permits
A drilling permit is a legal authorization from a state regulatory agency allowing an operator to drill an oil or gas well at a specific location. Permits must be obtained before any drilling can begin and include details about well depth, casing program, and operator information.
Well permits are a leading indicator of future drilling activity. A surge in permit applications signals operator confidence and upcoming rig activity, while declining permits suggest a slowdown. Permit data typically leads actual drilling by 30-90 days.
Texas consistently leads the nation in drilling permits due to its size and prolific basins (Permian, Eagle Ford). California, Ohio, Wyoming, and Louisiana follow with extensive historical records going back over a century.
Major oil-producing states (Texas, Oklahoma, New Mexico, North Dakota, Colorado, California, Louisiana) update permit data daily. Other states typically update weekly. We aggregate all sources for comprehensive coverage.
Drilling permits typically include: operator name, well name and number, surface and bottom hole location (GPS/survey), proposed depth, formation target, lease information, and anticipated spud date.
Our well permit database contains records dating back to 1864 (New York), with comprehensive coverage from most states since the early 1900s. This makes it one of the most complete historical drilling permit datasets available.
