Where is your property located ?
Allegheny county PA
PA was a right of capture state. Which means company could frac up to your property line and draw the gas from under your property.
I'm not sure if that still holds true.
However, this should not compel you to sign a bad lease. Because, depending on the size of your property the company could not capture all of the oil/gas under the property. It would be in the company's interest to sign a lease with you to be able to develop the full potential of the property.
So make your best deal.
