Each lease has a name, a Railroad Commission district and a lease number. Your check stub prints them, or a version of them. Search the name on your stub, open the lease, and compare the “oil sold” and “gas sold” volumes for the month with the barrels and mcf on your stub.
We hold 903 leases in Gaines County, of which 480 reported production recently. The state publishes county totals two to three months late, so Jul 2026 is the newest month.
