Yes, the operators understand the geology and the reservoir performance for the area. Most buyers offer an amount based upon the known current production for a certain number of years, discounted for the time value of money. Some offer a bit more if a well is permitted and drilling.
If the buyer has offered $100,000, then highly likely that the upcoming wells are worth quite a bit more. Remember that the buyer intends to make a profit off of their purchases. Not only should one consider the current wells with permits, but the potential for infill wells. Our family thinks generationally and that has paid off in $$$ by being patient and waiting for plays to develop.
The Directories tab above has Pecan Tree appraisers. They have a tool that can help. I have not used them, but the owner of the company has given several excellent presentations at NARO meetings.
