DUNCAN OIL, INC.
Reported value by year
What DUNCAN OIL, INC.'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.
The line breaks where the operator filed nothing that year. A gap is a gap, never a zero — the Commission holds no report for those months, which is a different fact from a year of no production.
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.
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 0 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 |
|---|---|---|
| R38 | Rule 38 well-density exception | 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 — 1 May 2001 to 1 May 2001. 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 Feb 2001.
