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 36 leases in this field that have a page here — 90% of the register's 40 — so it understates the field.

Field number 28843666, from the Railroad Commission's field register. The register's own index resolves 40 leases and 358 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.
