A full read of activity around your Niobrara County tract

Recent permits, active operators and horizontal mix — in one report, with sources.

Weighing an offer to sell your Niobrara County minerals?

Buyers make unsolicited offers on mineral rights constantly, and the activity on record here is the context that tells you whether an offer is well-timed. Niobrara County has 28 new drilling permits in the last year, 73 horizontal permits and 4 active operators on record. New drilling — especially horizontal wells that can drain a tract from a mile away — is what moves both a mineral tract's value and your leverage in a sale. This page shows that activity free; watching the county tells you the moment it changes, so an offer never lands before you know what's driving it.

This is public WOGCC activity — the same data a mineral buyer looks at, in your hands. It is not an appraisal, and not a record of who owns the minerals.

This report compiles and structures publicly available oil & gas records from the Wyoming Oil and Gas Conservation Commission (WOGCC) — drilling permit applications (APDs), operator, status, and location. 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 the official WOGCC record. Activity is mapped to the surface hole location (SHL) the operator filed with the WOGCC, not your 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.
