MONAHANS, N. (ELLENBURGER), 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 5 leases in this field that have a page here — 83% of the register's 6 — so it understates the field.

Field number 62417360, from the Railroad Commission's field register. The register's own index resolves 6 leases and 17 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.
