Colleen, your mineral interest is pooled in a drilling unit and you receive royalty on any well drilled in that unit. Your lease is therefore Held By Production (HBP). That means your lease remains in force as long as there is continuing production not interrupted for more than a set period, usually 90 to 120 days depending on language regarding continuing operations. There is no need for a company to extend your lease, they hold it by production.
You did not mention property that may be outside of the production unit. Hopefully there is a pugh clause in the lease which would require the outside property to have the lease renewed to be held or it will be available to be lease by others in the market.
Horizontal Pugh clauses now appear in most standard form leases. And in unconventional plays it is unusual but not unheard of for tracts immediately adjacent to a economic unit to not be included in their own producing unit unlike conventional plays.
Thank you skip, in still new to this realm so im learning.
You're welcome, James. Being a mineral owner and a royalty interest can be complicated. It takes a little work to be a good steward of your asset. Do not expect the industry or the state to look out for your interests.
