The Railroad Commission assigns each lease to a field: the underground pool or formation it produces from. A field can cross county lines and hold leases from many operators. Leases in the same field often move together, because they draw on the same rock.

That makes the field a fair yardstick. If your lease fell sharply and the rest of Mad Dog (Strawn) did not, that is worth a question to your operator. If the whole field fell, the cause is probably geology or price, not your check.

The field trend above sums every lease in the field, so it is a good comparison for the lease page of any lease listed here.

A field is a name and number the Railroad Commission gives to a group of wells that draw from the same reservoir. The Mad Dog (Strawn) field is field 56515500 in district 7B, with 2 producing leases in 1 Texas county.

Can I use the field to check my own royalty?

If your stub names a lease in this field, the field trend shows whether output fell everywhere or only on your lease. A drop across the whole field usually comes from price or reservoir decline, so ask the operator about your lease only when it fell alone.

How current are these numbers?

The state publishes lease production two to three months after the month it covers, so Jul 2026 is the newest month here.
