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 Maxey (Silurian) 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.
