La. Stat. tit. 31 § 90
Current with operative changes from the 2024 Third Special Legislative Session
When there exists on a tract of land burdened by a mineral royalty, or on a conventional or compulsory unit that includes all or part thereof, a shut-in well proved through testing by surface production to be capable of producing minerals in paying quantities, prescription is interrupted on the date production is obtained by such testing. If only a part of the tract burdened by the royalty is included in a unit and the unit well is on land other than that burdened by the royalty, the interruption of prescription extends only to that portion of the tract burdened by the royalty included in the unit. Prescription commences anew from the date on which the well is shut in after such testing.
