Reported value by year
What MAS OPERATING CO.'s leases reported, valued at the published monthly benchmark and summed by year. This is the state's volume times a published price — not what the company was paid, which no free source publishes.
Inspections and violations
What the Railroad Commission's field inspectors recorded at this operator's facilities. An inspection count tracks how much this operator runs in Texas; the rate beside it is what the inspectors found.

What the Commission did
- Notice of Violation 48
- Referred to Austin Field Ops for possible legal enforcement 10
- Issued a Severance/Seal Order 1
From the Commission's inspection and violation files, covering Aug 1 2015 to Aug 7 2026. The two are separate files with no key between them, so the violations here are not a subset of the 58 inspections that found this operator out of compliance — they are counted from their own file. 3 of the violations were still uncorrected when the inspector returned.
The Railroad Commission's docket file published 2025-02-05 names no case against this operator. That is what the file holds. It is not a statement that none exists.
Leases
Every lease is a page of its own: the monthly volumes the state published, multiplied by the monthly price. Value is lifetime, from Jan 1993.
