I’m a Weld County mineral rights owner too and although our property has been under lease since 1970 I’m just learning about how it all works. I thought I’d answer you the best of my knowledge until someone with a better understanding comes along. Despite the language in the lease oil producers are allowed by statute to pool acreage into a larger unit. This can work to your advantage or the other way around. Wells drilled on our land were pooled into larger units so we received only a third of our percentage of the production. More recently new wells were drilled on property we don’t own but were pooled into and now we’re receiving a portion of that.
I think Jenna has a good piece on her blog on this forum on the topic of forced pooling in Colorado that you might find helpful. But the bottom line is we’re kind of stuck with it. Colorado is allowing the state to override the contract for reasons of policy. It doesn’t line up with basic contract law principals but it’s hard to fight in court.
Hope that helps.
