Has anyone received any offers to drill for natural gas/minerals?  We received an offer to drill on 80 acres with a bonus of $1500/acre and 25% royalty for three years.  We currently receive royalty payments from other wells drilled on contiguous land that we own next to the 80 acres. So there are producing wells in the area, but we have not signed any new leases in 8 years and the terms back then were much lower. 

Any info would be much appreciated.
