First, look to your lease for what/any provisions that may address this issue of compensation for seismic surveys. Second, unless otherwise provided for in your lease, the $15.0/acre is usually a compensatory fee of liguidated “damages” paid to the surface owner for expedition of the survey. Is the survey being commissioned by your lessee? If not, yes, and if your lease does not confer exclusive seismic authority to your lessee, then a 3rd-party may be trying to get a permit to shoot and be offering to pay mineral/surface owners accordingly. This needs more knowledge on your part of what’s going on. A ready hard-core 3rd party may be trying to permit/pay a minority mineral owner as a gateway to the tract and avoid paying other owners, don’t stand for this if you are the surface owner. Also, make sure that the $15/ac. is for the whole/gross acres … not merely the 10-20’ width x ? length “sendero” of the survey lines. Ask for a pre-shoot map on the contemplated survey, require safe distance from wells, building foundations, etc. … they can off-set the energy source from these fragile culturals and still lay their receiver lines accordingly for a competent recording.
