You can easily double or triple that offer. We leased 6.8 NMA (net mineral acres) to Rosetta for 10K per acre in early 2018 and 20.8 NMA in a different section for 15K per acre from Centennial this past Summer.
How many acres do you have and who’s making the offer if I may ask?
Always have a lawyer look at the lease before signing it.
Suggest you post your question under Reeves County…go to Counties at the top of this page, then Texas and then Reeves Co. If you will give a more detailed legal description, like the Block and Section, or the survey abstract number your mother’s property is in I expect someone will be able to help you.
