Making contact for land/mineral rights lease DIMMIT COUNTY, TX

Our family owns 10 acres in Dimmit County, TX and we are very interested in seeing the availablity for making it available for leasing for minerals. We own 100% land and rights. My current understanding is that drilling units are currently 320 acres.

So, knowing we would be in a pool of landowners, I am just curious how that process gets started, if there is someone we should contact, or is it just a "waiting" game?

I would appreciate any info on this or help from anyone else's experience... either through this forum or through email.

Thanks a lot,

Jeff Bullard
