Solutions
For the people who answer for well integrity —by role, by portfolio, by regime.
BarrierLedger is one platform, but the questions it answers are different depending on who is asking: the engineer who owns the register, the manager who signs the review, and the lead who has to explain a portfolio.
By role
Three people, three different first question.
The same register, read differently. Nobody should need a second tool to answer their own version of “is this well alright?”.
Integrity engineer
Owns: The register, the statuses and the answers when someone asks why.
- One place for the barrier register, annulus readings and test records, instead of three files and an inbox.
- The governing limit, its source and its date recorded next to every annulus.
- Every status traceable to the inputs, the profile version and the approval behind it.
- The exception list first, so the day starts with what needs attention.
Wells manager
Owns: The integrity programme, the review and the audit exposure.
- A monthly review that is a workflow with a state, not a meeting: assessed, flagged, approved, locked.
- Overdue tests and open actions aged and visible before a review finds them.
- Period locking and restatements, with the previous version kept.
- The monthly pack exported without anyone rebuilding a spreadsheet.
Asset integrity lead
Owns: Several assets, several registers, one story.
- Every asset on the same method profile and the same status vocabulary, so portfolios are comparable.
- Risk-ranked views and data-quality lists per asset, so gaps are visible before they are asked about.
- Read-only and external-verifier accounts that do not count against the user count.
- A per-well report format that does not change between assets.
By regime
Four regimes, described only as far as our sources go.
These cards summarise what our own public-source research recorded. The full detail — including every place we found nothing — is on the regulations page.
Partly retrieved — gaps stated
United Kingdom
North Sea Transition Authority (NSTA), with OPRED as the offshore environmental regulator
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.
1 of 4 statements trace to a retrieved document; 1 are recorded as not retrieved or as no public source found.

United States
Bureau of Safety and Environmental Enforcement (BSEE), US Outer Continental Shelf
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.
2 of 3 statements trace to a retrieved document; 1 are recorded as not retrieved or as no public source found.

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

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

Where our regime picture is thin
By portfolio
One profile per well type, whatever the portfolio looks like.
BarrierLedger does not stretch a method across wells it was not written for. That is a deliberate limit, and it is visible in the product rather than buried in a footnote.
Offshore platform wells
The first archetype: production wells on a platform, with the three-annulus scheme (A, B and C) held per well and the monitored annuli assessed against their own limits.
Each well type has its own method profile; the producer profile is the first family.
Land wells
The wellhead plus tubing/casing annulus archetype, which is where most Canadian and onshore portfolios sit. Land wells follow their own method profile, not the offshore one.
Land and offshore are not served by one profile.
Operators moving off spreadsheets
Import the register as it stands, reconcile it line by line, and keep exporting it. Nothing about the current process has to be abandoned on day one.
Excel-first import, mapping and reconciliation.
Consultancies and verifiers
Each operator gets its own tenant, register, method profile and audit trail. Read-only and external-verifier accounts are free, and a partner arrangement covers several clients.
One subscription is never shared across operators.
The unassessable rule
Tell us what your portfolio looks like.
Bring the register, the well types and the policy your MAWOP figures come from. We will tell you which wells the platform can assess today and which need a profile of their own.
