Field number 71823666, from the Railroad Commission's field register. The register's own index resolves 277 leases and 646 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.
