My mother has received a letter from Vertical Energy. They are interested in purchasing her mineral rights. She has 3 sections in Beckham County and 2 sections in Washita County (totaling 66 acres). I have not been able to find much information about this company (Vertical Energy) and would like to know if they are a reputable company. I also have no knowledge of the process involved in selling mineral rights and want to make sure that she is not taken advantage of. Thank you in advance for any help / advice.
