SEVEN SISTERS, District 04, Texas
A field is the Railroad Commission's unit of geology and of regulation. Its spacing rule is what decides how many wells an acreage can hold.
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 25 leases in this field that have a page here — 52% of the register's 48 — so it understates the field.

Leases in this field
Every lease here files this field's number with the Commission and has a page on this site.
Field number 82380001, from the Railroad Commission's field register. The register's own index resolves 48 leases and 339 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.
