*Allocations to Federal Lands for associated gas and associated natural gas liquids in oil fields were the same as those for crude oil and the allocations of non-associated natural liquids were the same as those for non-associated gas. The province level small field allocations to Federal Lands for each province wree computed as the weighted average of resources allocated to Federal Lands over all plays in the province. In some cases where geologists allocated play resources to Federal Lands, the play may have had either negligible or no oil or non-associated gas so that the small field weighted average is negligible or zero. See, for example, the plays in Province 5 Eastern Oregon-Washington.
