Reported value by year

What HILCORP ENERGY COMPANY'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 986
  • Referred to Austin Field Ops for possible legal enforcement 14
  • Issued a Severance/Seal Order 10
  • Violation Corrected 5

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 1,204 inspections that found this operator out of compliance — they are counted from their own file. 66 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.

The five commonest of 20 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 — 12 Feb 1980 to 7 Mar 2024. 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 HILCORP ENERGY COMPANY operates. One physical pipeline is usually filed as hundreds of segments, so a system — not a segment — is the unit worth reading.
