FAQ
Questions people ask
How many wells were permitted in Starr County in the last year?
The Railroad Commission issued 5 drilling permits in Starr County in the twelve months to September 9, 2026, and recorded 10 completions and 3 first-production reports. A permit is permission to drill, not a well.
How do I get an alert when a permit is issued near my land in Starr County?
Choose your abstract on this page, or the whole county, and sign in. You get one email a week, only when something new is recorded after you sign up. The alert says whether an event is on an interest in your Mineral File, on a place you follow, or only nearby.
When is my first royalty check due after a new well?
Natural Resources Code section 91.402(a) says on or before 120 days after the end of the month of first sale of production from the well. The state's first-production month is the closest public marker, so the date on this page is the earliest, not a certainty.
Got a new well on your land?
The first check is due within 120 days after the end of the month of first sale.
