What the Commission did
- Notice of Violation 38
- 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 45 inspections that found this operator out of compliance — they are counted from their own file.
Commission dockets
Cases the Railroad Commission opened naming this operator. Most dockets are applications — commonly for an exception to the statewide spacing rule — and a small number are compliance orders.
| Type | What the Commission's remarks call it | Dockets |
|---|---|---|
| A37 | Rule 37 spacing exception | 3 |
| R37 | Rule 37 docket | 2 |
| AFR | no published meaning for this code | 1 |
| MIS | no published meaning for this code | 1 |
| R10 | no published meaning for this code | 1 |
The five commonest of 6 types this operator carries.
From the Commission's docket file published 2025-02-05. It is the only copy on the Commission's link, so nothing filed after that date appears here. The dates shown are the earliest and latest the record carries — 7 Jul 1998 to 20 Oct 2009. The file holds eight date fields per docket and the Commission publishes no key to which is which, so none is named here.
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.
