Our estimate: volumes the operator filed with the Commission, valued at the EIA first-purchase price for that month. It is not a payment anyone received, and it is not a royalty. It sums the 1 leases in this field that have a page here — 100% of the register's 1 — so it understates the field.

Field number 26512700, from the Railroad Commission's field register. The register's own index resolves 1 leases and 1 wells to this field by name, over every lease in Texas rather than only those with a page here. It resolves a lease by NAME and refuses an ambiguous one, so it counts nothing for a field that shares its name with another — which is why the lease count above comes from the field number instead.
