Based on the location and the Snodgrass name, I would spend some time thoroughly researching whether you hold rights in other areas of West Virginia before doing anything. If you unearth a considerable holding there, I would put some heavy research into your family roots.
Not to send you on a sensational “treasure hunt”, but if you’re a descendant of the same Snodgrass family that I dealt with in Ritchie, Marion, Doddridge, Harrison, and Tyler Counties (and also numerous properties in Texas), you may not want to do anything without an oil and gas attorney. Without some digging on your part, it’s impossible to determine but I can tell you that there’s a clan of your surname in that part of the country that has passed down minerals in counties across WV as well as many other states across the U.S.
I don’t have any experience dealing with the company you mentioned so I can’t speak to them, but there are a lot of crooked fly-by-night mineral buying companies that will sneak wording into a conveyance deed that essentially says you also “give” them any minerals you own in other areas. If you’re not careful, you might unknowingly give away a small fortune.
Best of luck
