OAK HILL (COTTON VALLEY), District 06, Texas

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 2,235 leases in this field that have a page here — 98% of the register's 2,275 — so it understates the field.

The discovery well's oil measured 54.1° API gravity, perforated at 9,855 ft.

Commission remarks: FIELD. EFFECTIVE 4/12/16.

Showing the 200 largest of 2,235 leases, by the value we compute. Every one of them is in the sitemap.

Field number 66461275, from the Railroad Commission's field register. The register's own index resolves 2,275 leases and 2,276 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.
