Seismic Survey question

Seismic survey questions in Anderson county TX. I’ve been approached by a company wanting to do a seismic survey on my property in Anderson county, aka Elkhart West Seismic Survey that’s well known and well documented.

I also own ~75 NMA that’s currently unleased but have been approached several times to lease and I’m seeing how serious they’ll get. They’ve upped the offer but just fishing.

Regarding the seismic survey… I was concerned about and didn’t want the explosive detonations on the ranch, 3 water wells etc, and the guy first said they could do just the receivers and no explosives. He wanted to meet in person and discuss so we did. At that meeting several weeks ago he proceeded to tell me they could NOT do that and would have to detonate explosives. Took his word back. He got a little pushy and I explained how he could leave out the same door he came in… Then he said we can test the wells before hand etc and buffer 500’ instead of 300’ etc. I said I’d think about it and just left it there. Now he’s calling again wanting to meet again. I told him no reason to unless we can agree which we have not.

I personally know others who have receivers only in their signed executed trespass permit. Curious what may be going on…and ideas or info that might be helpful.
