The permit feed carries a rolling recent window, so early years are partial. Well counts above come from the full current wellbore file.
This report compiles and structures publicly available oil & gas records from the Railroad Commission of Texas — drilling permits, completions, well status, and lease production. We monitor development activity and public filings near a location you tell us about; we do NOT determine mineral ownership, confirm what you own, or provide legal, tax, or investment advice. Nothing here replaces a title opinion, a landman, or reading the official RRC filing. Activity is mapped to the locations the operator filed with the RRC: the permit surface location (NAD27, precision disclaimed by the RRC) and, for horizontal permits in owner files, the W-1H terminus tract. Neither is a title-verified mineral tract. Data is current only as of the source vintage shown on the page. Our total liability for any report is capped at the amount you paid for it. Found an error? Reply to any email and a human will correct it.
