I’m a new mineral rights owner in Garvin County, Oklahoma, and am at a loss on calculating net mineral acreage. What does all this mean?
NE1/4 NE1/4 of Section 10, Township 3 North, Range 4 West;
W1/2 SE1/4 and the NW1/4 NE1/4 and the SE1/4 NW1/4 and the W1/2 SW1/4 NE1/4 and the SE1/4 SW1/4 NE1/4 all in Section 26, Township 4 North, Range 4 West; and
SW1/4 NW1/4 of Section 34, Township 4 North, Range 4 West
Those descriptions are gross acres. The first & third, are 40.00 gross acres. The second 190 gross acres. To get to a net mineral acre, you must know your fractional share of those tracts. In example, if you owned 1/4th fractional interest in the first description, you would own 1/4th of 40.00 acres, or 10.00 acres.
It helps if you read each aliquot set from right to left. So the first one is NE4 (160 acres) and 1/4th of that which is 40 acres.
The second one starts with the SE4 (160 ac) and W half of that, so 80 acres AND the NE4 (160 ac) and NW4 of that so 40 acres AND NW4 (160) then SE4 so 40 AND NE4 (160) then 1/4th of that (40) then half of that so 20 acres AND the NE4(160) then 1/4th of that (40) then 1/4th of that so 10 acres (80+40+40+20+10=190)
The third set is NW4 (160) then SW4 so (40).
As Todd said, you need the fractional share. Usually found in a deed or a will. Grandpa gives 1/4th of his acres to each of his four children, etc.
Thank you! The first seems to repeat NE 1/4 twice. Does that make sense?
Yes, in words it is the NE quarter of the NE quarter. The upper right quadrant of the upper right quadrant. Here is an article that will help.
