End-to-end well decommissioning · Permanent plug & abandonment

You only end
a well once Know the well before you plug it

What you don’t know about the well ends up as margin in the design and days on the rig. Endwell keeps the data, the plan, your team and your suppliers connected, so nobody spends the week stitching documents together.

Same data for everyone.
Your own view of it.

Each step of the detailed operations procedures (DOPs) is linked to the barriers it relies on, and every role sees it their own way: the engineer the well barrier schematic (WBS), the project leader the next approval, the supervisor today’s step. The same holds across every well in the campaign.

01

A procedure that
knows the well.

Every DOP step carries its well barrier schematic, its risks and any pending change. Every value shows where it came from, who changed it and which steps depend on it. As the work runs, each step records what was done, so the as-run DOP and the final report come from the same data.

02

Your suppliers do the work.
You keep the overview.

Main service providers plan and run the DOP steps they own, with the barriers they rely on in view. You follow every well’s progress, quality checks and cost in one place, and review each change before it reaches the approved plan.

03

Decades of well history,
in one place.

Logs, daily reports, integrity data and risk registers come together, wherever they live today. Your team adds its own fields, checklists and views, and changes them when the way you work changes. The history stays live through every step that follows, and is still there for whoever checks the well decades from now.

Every well makes
the next one easier.

Every well in the campaign has the same structure, so you can set them side by side. Durations, non-productive time and lessons learned on one well are in front of the team planning the next.

A-02 18 h → 26 h Losses in test
A-04 20 h → 19 h Lesson from A-02

Your AI never leaves the rig.

The AI model runs on your laptop. No cloud, no per-token bill, no quota, and no procurement case before an engineer can use it. Designed to keep working when the connection drops.

Same well.
Your job.

Find your role on a permanent plug and abandonment (PP&A) project, and see what changes for you.

D&W engineer

PP&A, drilling, completion and subsea engineers

Today

You confirm the well’s existing barriers from casing logs, cement reports and decades-old well reports. Then you draw the well barrier schematic (WBS) again for each concept and every DOP step.

With Endwell

The WBS is drawn from the well data, for every step. Correct one top of cement, and every WBS, DOP step and check that relies on it updates.

Ask“Which strings have no cement record below 2,500 m?”

Subsurface specialist

Geologists, geopressure, reservoir engineers, petrophysicists and rock mechanics

Today

You give source pressures, fluid gradients and formation-barrier properties for the concept, verify them on the WBS during planning and again at handover, and predict how pressures will develop after abandonment.

With Endwell

Enter them once, on the zone. Every barrier that depends on them shows it, and every WBS carries the same numbers.

Ask“Which barriers depend on the reservoir pressure estimate?”

Well integrity engineer

Technical system responsible for the well, wellhead and tree engineers

Today

You supply the barrier schematic, dispensations and annulus pressure history at concept. Three days before handover, you check the draft package against what was actually done.

With Endwell

Review the well as it stands. Each barrier comes with its tests, each risk with its tag and each dispensation with its owner. A failed test cannot quietly drop out.

Ask“Show every barrier element without an accepted pressure test.”

Project leader

Project managers and planning leaders

Today

You chase reviews, risk analyses, approvals and authority deadlines across folders. Then you stitch everyone’s input into the concept report and the activity program.

With Endwell

Every deliverable, risk and open action points at the well and barrier it concerns. Wells that share a concept share one program, each with only its own addendum. You see what blocks the next approval before you reach it.

Ask“What is still open before detailed planning on A-02 can be approved?”

Approver

Wells managers and area leaders

Today

You approve concept and detailed plans from milestone documents, and decide which wells need attention from management.

With Endwell

Three numbers across the campaign: open barrier concerns, wells ready for the next approval, and cost against estimate. Any one of them opens the evidence, and each approval shows the risk analyses, QA and cost behind it.

Ask“Which wells in the campaign have open barrier concerns?”

Main service provider

Supplier engineers on the main contracts

Today

You co-write DOPs, present your risk summary, sign the DOP offshore and join the lessons-learned review, each time from a different copy.

With Endwell

Work alongside the operator on the DOP steps you own, with the barriers you rely on in view. The operator reviews what you change.

Ask“Which of our DOP steps rely on the primary barrier?”

Wells supervisor

Drilling and wells supervisors offshore

Today

DOPs arrive from onshore mostly finished and are fine-tuned on the rig. Every change to the approved DOP goes through management of change.

With Endwell

Each DOP step comes with its WBS, risks and contingency. Propose a change against the step, not in an email. Designed for offline work at the rig site, with the as-run DOP and lessons learned kept on the well.

Ask“What are the barriers for the next step, and when was each last tested?”

Operations and maintenance leader

With production supervisors, who hand the well over and receive the final record

Today

You test the barriers within a week of handover, document valve status and sign the well over. When the work is done, a final package comes back to check and file: barrier schematic, test charts and open dispensations.

With Endwell

The record you hand over is the record you get back, with every barrier, test and dispensation that changed in between.

Ask“What changed on this well since we handed it over?”

Also for discipline leads who quality-assure the plans, rig economists and cost controllers, and the data managers who archive the well.

Frequently asked questions

Does Endwell replace our planning and procedure tools?

It can. The concept, DOPs, risks, evidence, handover and final report all work from the same well data, so there is nothing to keep in sync. Start with one well, bring in what you already have, and move over at your own pace.

Do we have to copy our data into Endwell?

No. Endwell has connectors for most of the places your data already lives, from SharePoint and Excel to WITSML, LAS and SEG-Y. It reads each source where it is and shows when one has changed since you last accepted it. Logs, schematics and reports stay attached as the original files.

Where does our well data go?

Your well data stays in your own workspace, shared only with the people you invite. The AI model runs on your laptop, so asking it a question sends nothing to a cloud service.

Is it built around NORSOK D-010?

Yes. Barrier envelopes are checked against D-010’s requirements for each source of inflow, and acceptance criteria are referenced by table number. Your own company requirements can be added alongside them.

Can our service companies work in it?

Yes. A supplier gets access to the DOP steps it owns, with the barriers it relies on in view, and you review what it changes.

What does it take to get started?

One well and the data you already have for it. Most teams start as design partners on a single workflow, such as a barrier review. Endwell is built and tested on public North Sea well data.

All’s well
that ends well.

Start with one of your wells. As a design partner, your team runs Endwell on a real workflow, such as a barrier review, and helps shape what we build next.
