I came across an auction for a mineral acerage in LaFlore Co., but I am new to this. How do you find out what the potential earnings are/what the property has been generating in recent months or years? I’ve done some reading but I have yet to come across the answer to this one…
Advice is much appreciated, thank you 
Le Flore is not the hotbed of activity in OK. There is only one permit in the whole county. If it won’t get drilled, not much point in owning it-for now. That is not a county where I would buy minerals.
In my opinion, it is very difficult for the novice to pick good mineral acreage as it requires deep pockets, a knowledge of the geology of the area, engineering information about production, a clue as to when and where the drilling rigs are doing, market prices, etc.
Past performance is past. The decline curve of a well(s) can give a general idea of the future production in the area. Prices are difficult to predict, but many folks use the NYMEX five year strip with a discount off of the Henry Hub gas and WTI based upon transportation difference and other factors. You need to know if the area has future potential for horizontal drilling, additional reservoirs, etc.
Many people can invest alternately in Royalty stocks and spread their risk. The pros have already picked up producing acreage in multiple basins and the returns are fairly predictable. Major oil company stocks or specialized royalty groups. Do your due diligence.
You can look up the well(s) productions on https://imaging.occ.ok.gov/. Given the area, the potential earnings arent great to put it politely. Its not my money but if it were, Id look elsewhere to invest it.
