I come upon this website today, first I was able to locate several past family members. Then I typed in the search box; Oil Drilling, or Oil Wells. There are hundreds of photos of days gone by of many topics, including the ND oil industry.
It's likely you can find your well, or something to do with the homesteaders of the land your minerals are on.
Happy hunting.
History Buffs will enjoy this webpage.
It's the Bureau of Land Mangagement dating from 1776-2006; snippets of information by year. Amazing to see the prices of land in the 1800 entry, along with the 6% interest. Who knew interest rates would have been that high back then?
Homepage on this site can lead you to find the homesteader of the land you hold minerals for.
