Great question, the only way I would think of that you would sell your mineral rights would be if you were selling the property, gas/oil companies generally lease mineral rights. When you are looking to sell property the value of the mineral rights is dependant on the size of the property, the current use of the mineral rights, but most importantly the current market for your mineral rights. Are you currently selling a home or property? Do you have a lease on the mineral rights? How large is the land we are talking about?
Right now new drilling in the Barnett Shale is almost nonexistant, Chesapeake Energy, one of the largest drillers in the Barnett Shale said earlier this year they would only have between 1-3 active rigs on the shale by years end.
I recommend focusing your efforts on negotiating the best price possible for the sale of the property that you own. Mineral Rights do of course play a part in your pricing strategy but some buyers have very little concern for these rights so do not over focus on them. If you would like to speak directly about selling your property or would like a more detailed opinion please contact me directly.

This may help you come up with figures for selling the minerals.
Also if a company is thinking about drilling in your area, then all homeowners in your area are in a similar position.
Many neighborhoods banded together to negotiate as one big group. This gave them the power to hire an attorney and negotiate a higher price for lease rights....not outright sales.
Something to think about.
Did you get an offer just to buy the mineral rights? That seems a little weird in today's environment. Possible, but strange to me. Drilling activity is off around here.
