Illinois Assignment of Overriding Royalty Interest with Multiple Leases that are Non Producing with Reservation of the Right to Pool: In the oil and gas industry, an Assignment of Overriding Royalty Interest (ORRIS) is a contractual agreement where the legal owner of an ORRIS transfers their rights to another party. In the case of Illinois, an Assignment of ORRIS with Multiple Leases refers to the transfer of overriding royalty interests across various leases in the state. When these leases are non-producing, it means that no oil or gas is currently being extracted from the leased areas. Non-production may arise due to various reasons like temporary setbacks, technical difficulties, or unfavorable economic conditions. However, despite the non-producing status of these leases, the assignment of ORRIS remains significant as it secures the interested parties' rights to future royalty earnings if production were to resume. Additionally, an important term within this type of assignment is the Reservation of the Right to Pool. Pooling refers to the practice of combining multiple leases or tracts of land into a single unit for oil and gas operations. By reserving the right to pool, the assignees maintain the option to merge their leased areas with adjacent tracts, maximizing the potential for production and enhancing economies of scale.
