In Phoenix, Arizona, there are various types of assignments of partial interest in oil and gas leases reserving an overriding royalty interest. Some common types include: 1. Standard Assignment: This type involves the transfer of a specific percentage or fraction of the owner's interest in the lease to another party. The assignor retains an overriding royalty interest, which allows them to receive a portion of the revenues generated from the lease. 2.

The consent of the lessor is usually required to ensure compliance with the terms of the original lease agreement. 3.

This type of assignment simplifies the ownership structure by consolidating all interests in the lease under one party. 5. Assignment subject to a Reserved Interest: Here, the assignor transfers a partial interest in the lease to the assignee but reserves a specific interest, such as the right to explore or develop a particular area within the lease. This type allows the assignor to retain some future benefits while realizing the value of the partial interest. 6.
