Regulations
What each regime asks for —and what our research actually found.
BarrierLedger is built around real integrity regimes, so this page names them. Every statement below is limited to what our own public-source research recorded, and every gap we hit is printed rather than smoothed over.
Reading this page
Every statement carries the source behind it.
Each regime statement is limited to what our own public-source research recorded, and the marker next to it says which kind of retrieval it rests on.
The four markers
Each statement carries the status of the source behind it, and the research file and line it comes from, so the claim can be audited rather than trusted.
- Source retrieved
- A public document was fetched and is listed with its URL.
- Reported in our research
- Recorded in our research from a retrieval, but the regulator’s own document was not fetched.
- Not retrieved
- The source exists but our research could not fetch it. It is context only.
- No public source found
- Our research found nothing. The gap is stated, not filled — “not found” is not the same as “not true”.
No approval claimed
Regime
United Kingdom
Our research records the UK offshore regime as NSTA/NORSOK-style: an offshore Safety Case regime, with NSTA well-decommissioning and stewardship expectations, and NORSOK D-010 / ISO 16530-2 conventions in common use.
North Sea Transition Authority (NSTA), with OPRED as the offshore environmental regulator
- Reported in our research
The UK offshore regime is an offshore Safety Case regime; NSTA well-decommissioning and stewardship expectations apply. Our research labels it NSTA/NORSOK-style.
Trace: docs/well/discovery/targets_uk_canada.md:224
- Reported in our research
NORSOK D-010 and ISO 16530-2 conventions are recorded as in common use for barrier philosophy and annulus/MAWOP conventions. Their applicability is explicitly left for the owner to settle, not asserted by us.
Trace: docs/well/discovery/target_list.md:95,129
- Source retrieved
A gov.uk search of the OPRED organisation filter surfaced no operator-specific well-integrity document; NSTA/OPRED integrity material remained generic.
Trace: docs/well/discovery/targets_uk_canada.md:285
- No public source found
No statement of, or citation to, the Offshore Installations (Offshore Safety Directive) Regulations, well examination, an independent verification scheme or Safety Case Report requirements appears anywhere in our research store.

Regime
United States
Offshore US operators on the Outer Continental Shelf are BSEE-regulated lessees/operators under 30 CFR Part 250. The sustained casing pressure driver is explicit and structural.
Bureau of Safety and Environmental Enforcement (BSEE), US Outer Continental Shelf
- Source retrieved
30 CFR Part 250, Subpart E — "Casing Pressure Management", §§250.519–250.531 — covers casing-pressure monitoring, diagnostic testing, record retention and corrective-action / casing-pressure requests.
Trace: docs/well/discovery/targets_us_australia.md:45
- Source retrieved
BSEE NTL 2009-G01 ("Casing Pressure") documented the evaluation and management expectations for wells with casing pressure. BSEE lists it as rescinded, so the current requirements to cite are the Subpart E regulations.
Trace: docs/well/discovery/targets_us_australia.md:45,47
- Not retrieved
Company-specific BSEE SCP or incident audit notices were not retrieved in our research; the driver we rely on is the structural OCS jurisdiction under 30 CFR 250 Subpart E.

Regime
Canada
Our research treats Canada as provincial regimes for conventional and heavy oil, mostly land wells, with the wellhead plus tubing/casing annulus archetype. One signed method profile must not be asked to serve both provinces.
Provincial: Alberta Energy Regulator (AER) and the BC Energy Regulator (BCER)
- Reported in our research
Canadian rows in our research are provincial — AER (Alberta) and BCER (British Columbia) — mostly land wells, wellhead plus tubing/casing annulus archetype.
Trace: docs/well/discovery/targets_uk_canada.md:224
- Source retrieved
The AER public compliance orders and closed investigations index pages were retrieved; neither names any operator on our shortlist. These are index and summary pages, so that is "no order surfaced in the index retrieved" — not an all-clear.
Trace: docs/well/discovery/targets_uk_canada.md:285
- Not retrieved
The BC Energy Regulator site was unreachable from our research host, so BCER enforcement was not checked.

Alberta per-operator well counts were not obtainable: the free AER Tableau views are search-by-licence, the all-Alberta well file is a paid catalogue product, and SEDAR+ returned HTTP 403 to scripted access.

Regime
Australia
The Australian driver is split. Offshore Commonwealth well activities sit under NOPSEMA; onshore wells sit under state regimes in Queensland, South Australia, Western Australia and the Northern Territory.
NOPSEMA (offshore safety and well integrity, Commonwealth); NOPTA is the Titles Administrator; onshore wells sit under state regimes
- Reported in our research
Offshore Commonwealth titles and well activities sit under NOPTA as Titles Administrator and NOPSEMA as the safety and well-integrity regulator: well operations management plans, well-integrity control measures and performance standards, and ALARP expectations.
Trace: docs/well/discovery/targets_us_australia.md:73
- Not retrieved
NOPSEMA guidance PDFs (the N-04600 series on well integrity and WOMP content) exist and are indexed, but the site refused our fetcher, so we cite them as context only and not as a retrieved document.
Trace: docs/well/discovery/targets_us_australia.md:75,264
- Source retrieved
Offshore production data is not publicly released: NOPTA states it is permanently confidential, which is why offshore active-well counts could not be verified.
Trace: docs/well/discovery/targets_us_australia.md:73,204
- Reported in our research
Onshore wells sit under state regimes: Queensland (Petroleum and Gas (Production and Safety) Act), South Australia (Cooper/Eromanga), Western Australia (DEMIRS well management plans), Northern Territory (Amadeus Basin).

Where the platform fits
What BarrierLedger does with all of this.
Not compliance, and not a filing. These are the four things the platform gives an operator who has to answer to a regime.
The limit is yours, with its source
Each monitored annulus carries the MAWOP/MAP value you supply as master data, with the source document, its date and the reference. The platform compares readings against your value and records which value governed.
The reasoning is recorded, not asserted
Every assessment keeps its inputs hash, source-file hashes, the method-profile version and the engine build, so a status can be shown rather than remembered.
Exceptions are first-class
A well that cannot be bled to zero, a missing or stale reading, an overdue test and an out-of-family annulus each raise a named exception with its flag and whether it blocks the review.
Reports for your own records, not submissions
Per-well integrity reports, test evidence packs and a monthly review pack are in-house outputs. You prepare any regulatory submission from them; the platform does not file, certify or approve anything.
What this page does not claim
- BarrierLedger is not approved, certified or endorsed by any regulator named on this page.
- Nothing on this page is legal or regulatory advice, and no statement here should be read as a compliance determination.
- Every regime statement above is limited to what our own public-source research recorded. Where it found nothing, the page says so rather than filling the gap.
- Outputs of the platform are in-house integrity reports. Regulatory submissions and official well records remain the operator’s responsibility.
Tell us which regime you answer to.
Bring the policy your limits come from and the reports you already have to produce. We will show you which parts of the record the platform can keep for you, and which stay entirely yours.
