Here we continue our discussion of the Texas Supreme Court’s opinion in Piranha Partners et al. v. Joe B. Neuhoff et al. determining that an assignment of an overriding royalty in minerals unambiguously conveyed the override in production under an entire lease. The Court concluded that circumstances surrounding the transaction didn’t matter. Here was the

Texas Supreme Court Rejects “Rigid Rules” of Deed Construction
The question for the Texas Supreme Court in Piranha Partners et al. v. Joe B.

Co-author Ethan Wood
Merry Christmas and Happy Holidays from all of us at Gray Reed! Assuming that most of you have been good this year (stay tuned for 2019’s Bad Guys in Energy to see who hasn’t), we hope Santa brought you everything on your Amazon Wish List. Our sympathies go out to those in the oilfield services industry in Texas—it looks like you got a lump of coal. In Mesa Southern CWS Acquisition v. Deep Energy Exploration Partners the Houston Court of Appeals upended the long-held view that mineral lien waivers violate public policy. Bah Humbug!

No Sovereign Immunity for the Texas Land Commissioner

Co-author Kelley Clark Morris
Suing a state and its public officials is difficult because of the doctrine of sovereign immunity. There are exceptions. State of Texas v. Signal Drilling, et al. presents several of them.
The rules
The State and its agencies are immune from:
- Suits seeking to construe or enforce contracts to which the State is a party,
- Declaratory judgment actions,
- Ordinary trespass to try title suits.
There are exceptions. For example:
- Claims against a state official in his representative capacity for non-discretionary acts unauthorized by law (the ultra vires exception).
- Claims for an unconstitutional taking of property without adequate compensation.
- Suits to require state officials to comply with statutory or constitutional provisions.

What is “Oil or Gas” as Used in a Pipeline Easement?
Co-author Rusty Tucker
In Texan Land & Cattle II, Ltd. v. ExxonMobil Pipeline Company a Texas court of appeals ruled that “oil or gas” is not limited to “crude petroleum,” but includes refined petroleum products gasoline and diesel.
The easement
Texas Land’s property in Harris County is burdened by an easement obtained by ExxonMobil from Humble Oil Company in 1919 that granted the right to lay, maintain, operate, and remove a pipeline for the “transportation of oil or gas” across Texas Land’s property. The easement does not define oil or gas.
The arguments
The sole issue was the definition of oil and gas as used in the easement. Texas Land contended that “oil and gas” granted the right to transport only “crude oil” or “crude petroleum,” but not refined products. ExxonMobil argued that “oil and gas,” as used in the early 20th century, included refined products such as gasoline and diesel.
