I’m in the process of understanding what my family interests are in a series of overriding royalty interests in several different Oklahoma counties.
The first issue concerns how a decimal interest, such as that contained on a division order, is calculated. I understand how a royalty interest is calculated (net mineral acres/unit spacing in acres X fractional royalty interest = decimal interest). My question: is this same formula used in the case of an overriding royalty interest where the interest is expressed as a percentage of production?
The second issue is an actual matter. My family has an overriding royalty interest in the production from a Canadian County gas well. The well was completed in 1980 and has been operated continuously as far as I can tell since then, although at least eight different operators have been involved. I have traced this series of operator transfers through the OCC online database without finding any indication that the well in question had become inactive. I have been told by the current operator that the well had been terminated and that he had a new mineral lease on the land where the well is located and had reworked the well so I had lost my ORRI for this well since the original lease had terminated.
The original lease was from two parties. One for 160 acres less a 30 acre parcel, and another for that 30 acre parcel. The lessor for the 160 acre parcel was a trust company acting as a trustee for the mineral owners. That trust company has recently quitclaimed the trust to the mineral owners who have leased this parcel to the present well operator. As far as I know, however, the 30 acre parcel is still tied to the original lease, and the production from this parcel is what my family’s ORRI is tied to.
My questions:
-
When production from a well has ceased to the point where the secondary lease term is triggered, is there some form of official notification or procedure that is required to be filed? If so, where would I find it?
-
If production from the well had not ceased enough to terminate an existing lease, and the original lease is still held by the same mineral owners, can those owners release that same interest? How would this work when a well had already been put in and had operated for nearly 30 years?
