Royalty Interest


I need help with this formula. Apparently it is for two leases, L2 gets a percentage and L3 gets a percentage.
Can anyone help me ASAP? The total is .00009993 for both leases. Thanks.

OWNER T 0.00009993 L2/L3
[6.875% of 1/4 of 1/11th of an Undivided 320 Acre Interest,
plus 6.875% of 112.5/50,000ths of an Undivided 320 Acre Interest, all at 12.5% Royalty]


There may be an NPRI involved. You need to determine exactly what is owned here. If you got this from an oil company for the DOI, ask the division order analyst to walk you through the numbers
