How deep are wells in Mountrail County?
North Dakota does not publish drilled depth as data — ND DWR's well file has no depth column. The depth of each well is written on the driller's own log, which ND DWR scans and publishes per well. Pull the wells near an address and open their logs to read the depths the drillers actually recorded on this ground.
How much does it cost to drill a well in Mountrail County?
We don't publish a Mountrail County cost estimate, because the honest input isn't there: cost tracks depth, and North Dakota doesn't publish depth as data. A dollar range built on a depth we don't have would be a guess dressed up as a local number. What we can do is point you at the companies that have actually drilled here — they quote from the same ground, and the logs on this page are their own filings.
