There are two separable questions here. One is the appropriateness of the agreements under which oil and gas are explored for, under which mineral rights are explored for, under which timber rights are given. That's one set of issues.
The other set of issues is that once you put that agreement into a written agreement, then you have a legally binding agreement. You may disagree with your landlord, or if you are a landlord, you may find that you really don't like a clause of your lease arrangement. That doesn't mean that you can unilaterally change it.
