SEM OPERATING COMPANY LLC
Reported value by year
What SEM OPERATING COMPANY LLC'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.
| Rule | What the Commission cited it for | Violations |
|---|---|---|
| SWR 3.8(d)(1) | Unpermitted Disposal of Oil and Gas Wastes | 44 |
| SWR 3.3(2) | Well Sign | 17 |
| SWR 3.3(3) | Battery Sign; Commingling Permit | 11 |
| SWR 3.3(1) | Entrance Sign | 5 |
| SWR 3.8(d)(4)(H)(i) | Pit Backfill Requirements | 4 |
The five commonest of 14 rules cited against this operator.
What the Commission did
- Notice of Violation 91
- Issued a Severance/Seal Order 2
- Referred to Austin Field Ops for possible legal enforcement 2
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 101 inspections that found this operator out of compliance — they are counted from their own file. 4 of the violations were still uncorrected when the inspector returned.
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 | 25 |
| AFR | no published meaning for this code | 2 |
| R10 | no published meaning for this code | 2 |
| CMP | no published meaning for this code | 1 |
| MIS | no published meaning for this code | 1 |
The five commonest of 7 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 — 3 Feb 2014 to 15 Nov 2022. 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.

Pipeline systems
The named networks SEM OPERATING COMPANY LLC operates. One physical pipeline is usually filed as hundreds of segments, so a system — not a segment — is the unit worth reading.
