Does anybody in Natchitoches Parish and/or Red River Parish, LA had past dealings with Energy Deep Resources, Inc., with an office located in  Shreveport, La.   They want to purchase a percentage of future  royalty interest (not mineral rights) from a friend before an operator drills in a section ...  It's hard to find information regarding this company by searching the internet.  In addition,  what information is available to a royalty interest buying company evaluating a  tract of land to arrive at an offer price for royalty interest for a potential customer before drilling has begun in a section?  Or how do they arrive at an "educated"  offer guess amount  that a landowner does not know about?   How can a landowner insure that an offering royalty interest company has made a current  fair price for  future, unknown production revenue(s) before a drilling operator drills in a section and just accepting a  price offer blindly,  which often winds up being foolish ???  Thanks in advance for your information and opinion.
