Regulations

The regimes operators answer to, with the source behind every statement.

What the UK, US, Canadian and Australian regimes ask of a well-integrity programme, summarised from the public documents cited beside each statement. The operator determines which regime applies to each well, and BarrierLedger keeps the record behind it.

Regime

United Kingdom

UK offshore wells sit on the UK Continental Shelf, licensed and stewarded by the NSTA. The regulator publishes the licence, field and production data behind UKCS activity, and holds well and field records in its National Data Repository.

North Sea Transition Authority (NSTA), with OPRED as the offshore environmental regulator

What the regime sets out

  1. UKCS licence, field and production data is published by the North Sea Transition Authority.

  2. Well and field records for UKCS wells are held in the NSTA National Data Repository.

Public documents for United Kingdom

Regime

United States

Offshore operators on the US Outer Continental Shelf are regulated by BSEE under 30 CFR Part 250. Casing-pressure management is explicit and structural.

Bureau of Safety and Environmental Enforcement (BSEE), US Outer Continental Shelf

What the regime sets out

  1. 30 CFR Part 250, Subpart E — Casing Pressure Management — sets out casing-pressure monitoring, diagnostic testing, record retention and corrective-action requirements for OCS wells.

    Source US Government Publishing Office / National Archives — 30 CFR Part 250 — Oil and Gas and Sulphur Operations in the Outer Continental Shelf (opens in a new tab)

  2. BSEE Notice to Lessees NTL 2009-G01 set out the evaluation and management expectations for wells with casing pressure; BSEE lists the notice as rescinded, and the Subpart E regulations carry the current text.

Regime

Canada

Canadian wells are regulated provincially. Most portfolios are land wells, with the wellhead plus tubing/casing annulus as the common archetype.

Provincial: Alberta Energy Regulator (AER) and the BC Energy Regulator (BCER)

What the regime sets out

  1. The Alberta Energy Regulator publishes its compliance orders.

  2. The Alberta Energy Regulator publishes its closed investigations.

  3. British Columbia publishes a well surface-hole status dataset through the BC Data Catalogue.

Regime

Australia

Australian regulation splits between the Commonwealth offshore regime and the state onshore regimes.

NOPSEMA (offshore safety and well integrity, Commonwealth); NOPTA is the Titles Administrator; onshore wells sit under state regimes

What the regime sets out

  1. Offshore Commonwealth well activities sit under NOPSEMA as the safety and well-integrity regulator, with NOPTA as the Titles Administrator.

  2. NOPTA publishes its position on the public release of offshore petroleum data.

  3. Queensland onshore petroleum is administered under the Queensland Government’s petroleum and energy framework.

  4. Onshore petroleum and well management in Western Australia is administered by the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS).

Where the platform fits

What BarrierLedger does with all of this.

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.

  • The record an inspector asks for already exists

    Locked monthly reviews, WIT evidence packs, the actions register and the incident log mean the history behind a well’s status is already assembled when an audit or inspection asks for it.

About this page

  • Every statement above is drawn from the public document named beside it; nothing on this page is legal or regulatory advice or a compliance determination.
  • BarrierLedger is not approved, certified or endorsed by any regulator named here. Its outputs are in-house integrity reports; regulatory submissions and official well records remain the operator’s responsibility.
