My wife and I, along with her three siblings and their spouses, own 50 net mineral acres in the S/2 of 2-5n-3w. These minerals are currently not leased, and have not been for the past 30 years. We have been approached by several land men over the last two years, but each time they withdraw their offers because of concerns that these minerals are held by production related to the Flint Creek Unit that has been operating in this area since 1966. We have obtained copies of the unitization application and the subsequent ruling by the OCC to approve the creation of the unit. All of these documents clearly indicate that the land under which our minerals reside was not and has never been included in the Flint Creek Unit's boundaries. Our family has owned the land and minerals in question for 50 years, and have never received any royalty income from Flint Creek production. Some of the land men have indicated that leases that were in force back in the the late 1940's and 50's contained language which has created a "tie-in" between our part of section 2 and that part that is actually included in the Flint Creek Unit. Does anyone have any suggestions as to how to go about removing this barrier to leasing our mineral interest? Any and all help/suggestions would be deeply appreciated .
