BLOCK 31 (ATOKA 7900), District 08, 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 3 leases in this field that have a page here — 43% of the register's 7 — so it understates the field.

Field number 09358090, from the Railroad Commission's field register. The register's own index resolves 7 leases and 16 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.
