VANCO OIL & GAS CORP.
Reported value by year
What VANCO OIL & GAS CORP.'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.

|---|---|---|
| SWR 3.3(2) | Well Sign | 190 |
| SWR 3.14(b)(2) | Inactive Unplugged Well | 189 |
| SWR 3.8(d)(1) | Unpermitted Disposal of Oil and Gas Wastes | 115 |
| SWR 3.3(1) | Entrance Sign | 100 |
| SWR 3.13(a)(6)(A) | Surface Control of Well | 71 |

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 580 inspections that found this operator out of compliance — they are counted from their own file. 80 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 |
|---|---|---|
| GFC | no published meaning for this code | 7 |
| PPP | Compliance order | 3 |
| IRT | no published meaning for this code | 2 |
| ENF | Enforcement and penalties | 1 |
| INW | no published meaning for this code | 1 |
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 Jan 2000 to 28 Oct 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 VANCO OIL & GAS CORP. operates. One physical pipeline is usually filed as hundreds of segments, so a system — not a segment — is the unit worth reading.
