Louisiana practitioners and their clients tend to know this particular point of Louisiana law, but it could surprise out-of-staters (known in their native habitat as “Texans”), so it’s worth a reminder:

Under Louisiana Mineral Code art. 122 and art. 129, a lessee in a mineral lease is not relieved of its statutory duty to perform the lease as a reasonably prudent operator unless the lessor has expressly discharged the lessee in writing. The original lessee, along with all assignees and sublessees, are solidarily liable to the lessor for the whole performance of the obligations imposed by the lease.

Coke or Pepsi? Elvis or the Beatles? Should there be a designated hitter? Fixed or floating royalty? Among the great debates of recent decades, few have proven quite as frustrating as the great “Fixed v. Floating” royalty debate in Texas jurisprudence.

A royalty can be conveyed or reserved in two ways: as a fixed fraction of total production (fractional royalty interest) or as a fraction of the total royalty interest (fraction of royalty interest). The fractional interest is “fixed” because it is untethered to the royalty in a particular oil and gas lease. A fraction of royalty is “floating” because it varies depending on the royalty in the lease.

We’re not saying you should do it, but there is a recipe for ridding oil and gas leases of pesky burdens: Enter into a new lease covering the same interest as the earlier lease and omit any reference to an intent that the later be subordinate to the earlier. You don’t even have to release the earlier lease. So says TRO-X, L.P. v. Anadarko Petroleum Corp.

You might remember a report on this case at the court of appeal, where we marveled at the skillful (or fortuitous, we’ll never know) way the Anadarko landman won the day via email.

In Murphy Exploration & Production Co. — USA v. Adams the Texas Supreme Court held that an offset well clause in an oil and gas lease did not require the lessee to drill wells calculated to protect against drainage. Four dissenting justices believed the majority disregarded the well-established meaning of “offset well” used in the oilfield for decades.

A few things you should know about the acreage retention clause:

  1. Foremost and always, read the instrument – not all clauses are created equal. But you know that.
  2. Consider the clause before perfunctorily filing P-15’s, plats, and other RRC forms.
  3. Absentmindedly relying on field rules to determine how much acreage you can retain? Do so at your peril.  And while your’re reading, read the rules pertaining to your acreage!

Two Texas Supreme Court decisions published on the same day confirm that retained acreage clauses that vary in language from one instrument to another will likely vary in effect. Depending on the language, the lessee might not be able to maintain all the acreage it planned on holding.

Defendants accused of stealing trade secrets often claim that publicly available information can’t constitute a trade secret. Sometimes yes, but mineral ownership that can be determined from the public record only after lengthy, expensive, and labor-intensive research in the county courthouse can have trade-secret protection, according to Eagle Oil & Gas Co. v. Shale Exploration, LLC.

 It began like a routine exploration venture …
