In Montana, time is not the enemy of a mineral owner. No dormant mineral act exists, so a severed interest is not lost to the passing of years alone.
Quick answer: Mineral ownership in Montana is durable. Montana has no dormant minerals act, so severed minerals do not lapse through nonuse. It does have a surface owner damage and disruption law. For an owner, that makes the real question what the interest is worth, not whether it survives.
Under current Montana law, a severed mineral interest is not forfeited for going unworked. As of June 2026.
With no lapse rule in play, an owner in Montana should focus on documentation: clear title and a reliable way for operators to deliver royalties. Montana produced about 28.5 million barrels of crude oil and 43.7 billion cubic feet of natural gas in 2025, according to the EIA, so mineral and royalty interests here trade actively.
An owner stays protected by recording the interest, updating contact details after any move, and claiming royalties before they are remitted to the state as unclaimed funds.
Montana permits compulsory pooling, so an owner who will not sign can still be unitized and paid according to the rules rather than vetoing the well.
Montana has a surface damages or surface owner protection act, so where minerals and surface are owned separately an operator owes the surface owner notice and compensation for disturbance.
No. Montana law keeps a severed interest intact regardless of how long it goes unused.
No timeframe applies. Montana does not terminate idle interests for nonuse.
Yes, Montana permits forced pooling.
