In Piranha Partners et al v. Joe B. Neuhoff et al, the Texas Supreme Court examined a written assignment of an overriding royalty interest in minerals produced from land subject to an oil and gas lease in Wheeler County, Texas. The Neuhoffs claimed the assignment conveyed an interest only in production from the well specifically identified in the assignment. Piranha Partners claimed that the assignment conveyed an interest in production from any well drilled on the identified land, or alternatively, in all production under the identified lease.
The assignment stated:
[Neuhoff Oil] does hereby assign, sell and convey unto [Piranha] . . . without warranty or covenant of title, express or implied, subject to the limitations, conditions, reservations and exceptions hereinafter set forth . . . all of [Neuhoff Oil’s] right, title and interest in and to the properties described in Exhibit “A” (the “Properties”)
