P-18 deadlines and penalties: what late or faulty filings cost
The RRC Form P-18 is due by the 15th of the month following each reporting period. Filings that are late or that do not reconcile can trigger manual review and sit in an error state until corrected. As a pattern, that strains your standing with the Commission, and hydrocarbons that cannot be traced to a source are allocated back to the producing properties under Statewide Rule 56.
When the P-18 is due
The Skim Oil/Condensate Report is filed monthly and is due by the 15th of the month following the reporting period. Every facility you operate files its own report, every month, with no grace for a missed cycle.
What happens when a filing is late or out of balance
Filings that arrive late, or whose fluid balance does not reconcile to the barrel, can trigger manual review by the Commission or come back returned until corrected, and the next monthly P-18 cannot be started until the previous submission is approved. You are not locked out of LoneSTAR, but a recurring pattern strains your standing with the Commission and invites closer scrutiny. And as the RRC moves more of its forms into LoneSTAR over the next couple of years, cross-form checks, such as whether P-18 volumes agree with the H-10, are widely expected to follow.
Allocation exposure under Statewide Rule 56
Statewide Rule 56 governs whether recovered hydrocarbons are identifiable or nonidentifiable. Volumes that cannot be traced to a producing source are allocated back to the producing properties in proportion to the water each one sent, and the property operator reports them as its own production on Form PR. For a multiple-operator system the rule applies that allocation only to unidentifiable volumes above a tolerance ratio of one barrel of hydrocarbons per 2,000 barrels of produced water received. Rule 56 contains no seizure or confiscation provision; the exposure is simpler than that, in that barrels you cannot trace stop counting as yours. Keeping every barrel attributable to a producing source is the protection.
How to stay clear with the Commission
- Reconcile the fluid balance to the barrel before filing
- File by the 15th, every month, for every facility
- Keep run tickets and source documentation ready
- Correct flagged or pending filings quickly, before penalties accrue
Frequently asked
What is the penalty for filing a P-18 late?
Late or non-reconciling filings can trigger manual review and leave a filing in an error state until it is corrected, with penalties able to accrue. As a pattern, it strains your standing with the Commission. Confirm current penalty specifics in the official RRC P-18 instructions.
What actually happens if I keep filing late?
Late or faulty filings rarely cause a single dramatic event, and you are not locked out of LoneSTAR. The cost is cumulative: penalties can accrue, returned filings block the next monthly report until the previous one is approved, and a pattern of problems strains your standing with the Commission and makes your account one that draws review. That scrutiny is expected to deepen as the Commission consolidates more of its forms into LoneSTAR and gains the ability to cross-check them against each other.
Can a late or incorrect P-18 be fixed?
Yes. LoneSTAR supports Corrected reports, and pending or flagged filings can be worked directly with RRC staff to refile clean and bring the account back into good standing.
What happens if recovered hydrocarbons cannot be traced to a source?
They are allocated back to the producing properties in proportion to the water each one sent, and reported as that property’s production on Form PR. Keeping the fluid balance reconciled and every recovered barrel traceable with run tickets and documentation is what keeps them attributable to you under Statewide Rule 56.
