You may or may not have the mineral right on your surface property depending on the title chain of the land before you bought the surface property. If any previous owners never reserved the mineral rights to theirselves when they sold, conveyed or granted the land property to next owner, then you most likely have the mineral right. If you live in a developed home community of a city, the home owner community association will determine your percentage of mineral right of the whole community land according to your lot size. Then home owner association will deal with oil/gas or land service company for leasing contract. If you live in a rural area (you may have a large tract of land), you have to deal with oil/gas or land service company directly by yourself to sign a oil/gas lease agreement. Remember state government regulates well spacing, usually 40 acre or more per well. If your tract is small, you still can lease it out, but it will be pooled with your neighbor's tract by oil/gas developer to satisfying state government regulations. And you will share the production revenue with your neighbor too proportionally with size of you tract when the well produces and sells oil/gas.
