Ward county 3D survey

Understand there will be a 3D survey of about 500 square miles in the Grandfalls area.

Recently got approached by Dawson to perform survey on my surface. Block 33 Section 1.

I also received a letter from Dawson to survey my land, Block 34, Section 60. What is the meaning? And what am I going to do? They are willing to pay $200 to me to do a survey on my property. Need help from anyone please. Thank you. John
