Enter a legal description and see the section drawn: where it sits in its township, which sections touch it, what the aliquot parts are worth in acres, and how to read the description on your deed. Nothing to sign up for.
Oklahoma townships are numbered north of the base line and east or west of the Indian Meridian. A description like Sec 14-11N-14W means Section 14, Township 11 North, Range 14 West.
Almost every mineral deed, lease and division order in Oklahoma, Kansas, New Mexico and most western states describes land using the Public Land Survey System. Once you can read it, your paperwork stops being mysterious.
Read a description from the smallest piece to the largest, right to left. In SW/4 NE/4 of Section 14, Township 11 North, Range 14 West:
So the description above is a forty acre tract. If you own an undivided one eighth of the minerals under it, you have five net mineral acres. Our calculators will do that arithmetic and the royalty decimal that follows from it.
Sections are not always exactly 640 acres. The survey had to reconcile a square grid with a curved earth and with errors made in the 1870s. Correction lines absorb the difference, so sections along the north and west edges of a township are frequently short or long. A "lot" number in your description usually means an irregular piece created by that reconciliation, or by a river.
Township and range are not addresses. Two tracts can share a section number and be a hundred miles apart. Always carry the township, the range, and the direction of each.
Oklahoma has two meridians. Most of the state is surveyed from the Indian Meridian. The panhandle uses the Cimarron Meridian. If a description does not say, the county tells you which.
Your deed may describe more than you own. A legal description says which dirt. Your fractional interest says how much of the minerals under it are yours, and those are separate numbers. This is the single most common confusion we see.
Give us a legal description, or just a county and a family name, and we will pull the chain of title and tell you what is actually yours, what is producing on it, and what it is worth. Free, no obligation, and useful whether or not you ever sell anything.

It is a reading aid, not a survey, and it does not account for correction lines, government lots, irregular sections, or river boundaries, all of which are common. For anything that turns on exact acreage, use the recorded plat and a licensed surveyor.
