After some researching we found that his father conveyed his Carter County, Oklahoma minerals via a term mineral deed fifty years ago. A term mineral deed is a type of reversionary interest. According to Black's the definition of [reversion](https://thelawdictionary.org/reversion/) is: In real property law, a reversion is the residue of an estate left by operation of law in the grantor or his heirs, or in the heirs of a testator, commencing in possession on the determination of a particular estate granted or devised. And a reversionary interest is: The interest which a person has in the reversion of lands or other property. A right to the future enjoyment of property, at present in the possession or occupation of another. Bruce's father with the tie and cigarette. He sold his Oklahoma mineral rights on a term mineral deed to finance his "Summer of Love" exploits. The man knew how to smoke. In landman terms, this just means that the property in question will automatically go back to the original grantor or the successors of that grantor's interest to the property when a certain condition is met. The conditions could include such mechanisms as a back in, an overriding royalty interest to working interest option and others which Berlin will cover at a later date. This reversionary interest in question today was simply a term that was written into a mineral deed. Terms are very common in the oil and gas business. The most common instrument with a term is the [oil and gas lease](https://www.berlinroyalties.com/oil-scout/the-basics-of-the-oil-and-gas-lease). However, conveyances of a fee mineral interest can also contain a term and that is what Bruce owned. Long story short, Bruce's father conveyed his minerals to a grantee in 1967 for a term of 50 years. Occasionally, the term of a term mineral deed may be perpetuated by production, but that was not the case here. Simply put, the minerals rights owned by Bruce's father would **revert** to his heirs (if they were conveyed the reversionary rights) 50 years to the day from the original effective date of the conveyance. Often, reversionary interests with longer terms are lost in the inter-generational shuffle of heirs. In this case, Bruce is fortunate that the attorney who originally rendered the title opinion for the operator made a note of this term instrument so the operator was able to track it through the years. Bruce is also lucky that the operator of the lease had drilled the original well in the 1970s and continues to operate the lease to the present day. This is uncommon.
