It usually means that it is a really old well and they do not have much information on it. You may have better luck with the well record site. Test Put 2422N02W in the Legal Location box. I found a bunch of old wells with no names. You would have to click through each one.
The other place to look is the Gross Production site. Gross Production There are two Nuendorf wells-both are plugged and abandoned. There are couple of wells still active, but you would have to check the spacing to see if they are in your acreage.
