Wellbarrier Software

Wellbarrier software is a cloud-based solution that helps you visualize your wells and the well barrier elements, with related qualifying and monitoring requirements. It gives you a clear and common understanding on safeguarding and maintaining the integrity of your wells. The Wellbarrier software incorporates the barrier definitions that embrace the "two-barrier principle" as a core component of establishing well barriers.


Time Efficiency

Prepare well barrier integrity information in a quick and easy manner.


Ensure it’s verified by using the electronic verification function.


Provide standardized presentation of graphics and language.


Save all your work in one easy accessible company library.

"I always found the Wellbarrier approach to visualizing the well barrier cases in NORSOK to be simple and appealing, and I suggested to some of the folks that I worked with...to look into NORSOK and to the methods used by Wellbarrier to better understand "intent" when it comes to well integrity."

Well barrier and well integrity software

Reduce risk – prepare high quality well barrier illustrations

The Wellbarrier Illustration Tool enables you to create well barrier illustrations in a clear and consistent manner for all types of well activities, from drilling top-hole to P&A of the wells. It is our core offering and includes the following functionalities:


Well Overview

The work you have created is organized in a logical library. When selecting a well it shows the current well barrier illustration and status of the well. From here you have access to all stored data and other illustrations that is produced for this well.


Well Schematic

The Well Schematic is based on the barrier illustration. Reservoir and barrier coloring are removed and the illustration is shaped to the desired curvature in a quick and effective manner together with appropriate automatic annotation.


Well Barrier Pressure Plot

An alignment of the well barrier illustration and the pore and fracture pressure curves will give you a quick and effective view of the formation strength at critical points in the well. You can easily see how any pressure origination from the reservoir or from the surface will affect components or the overburden formation in the well.


Well Control Action Form

The Well Control Action form has an easy to use flow diagram editor. You can map how critical well incidents are proposed to be handled. This is a useful attachment to include in i.e. coiled tubing operations and likewise where the equipment in use is not necessarily well known to the rig.


Sequence Diagram

The Sequence Diagram is a representation of a chosen selection or all the well barrier illustration you have prepared for the well. This can be output on A4, A3 or large size plotter paper and be made available in meeting rooms or places where the stakeholders have access and can see the planned progress of the well activity.

“Great product which really helps show the barriers during each stage of the operations.”

Drilling and Well Operations


Illustrations Available

Completion diagrams and assembly drawings

Wellbarrier's completion functionality gives you a common platform to document all components and parts that are placed in a well.

Get a clear picture, with all your completion information in one place

The Wellbarrier Illustration Tool's completion diagram can be created to have a consistent representation of the installed completion.  Tubular and component data is manually or automatically input and is required to undertake a subsequent MAASP calculation for the A-annulus.


Assembly drawings are set up separately for each completion assembly to show more specific details of the assembly.  This is done not to overpopulate the completion diagram as well as securing access to specific assembly, information and data needed for the MAASP calculation.

Risk Assessment


Assess risk in an objective manner

The Risk Assessment form uses the well barrier illustrations and the defined elements. Using barrier elements removes the subjective approach and establishes a firm reference is easy to agree on. Mitigating actions are suggested for the yellow and red risks.



Our main focus is to support our customers with knowledge related to well barrier integrity. We can help our customers to get a smooth implementation of Wellbarrier illustration tool, give advice of how to standardize the processes of defining the well barriers, and help setting up the company well library. We can review the library to see if there is a need for any improvements.

Project Services

Let us revise your well barrier definitions and give advice of how to implement a structured way of documenting the safety in the well. Let us evaluate if your new technology can qualify as a barrier element.

When there is a need for a second opinion

Our main focus is to support our customers with knowledge related to well barrier integrity. We can help our customers to get a smooth implementation of Wellbarrier Illustration Tool, give advice of how to standardize the processes of defining the well barriers, and help setting up the company well library.

When a second opinion is needed, we can review the library to see if there is a need for any improvements.

Our services are ready for you

Building company library

We can assist you with creating a comprehensive and actual well barrier library adjusted to your company’s requirements and only accessible for your representatives. This allow you to have your entire well portfolio available in a consistently presented manner. The availability of such library will ease the planning work for future well activities since well schematics can be used as reference and adjusted for new wells. Furthermore, intervention equipment can then be easily added to the illustration to give a correct representation of the well barriers for the specific job to be done.

Quality review of customer library

The purpose of the review is to ensure high quality of the WBS (Well Barrier Schematics) with respect to well integrity. We focus on good practice for definition and illustration of well barriers. We also evaluate the information contained in the fields of qualification and monitoring to ensure valid information and consistency. By evaluating a selection of Well Barrier Schematics, we provide recommendations on areas to improve.

Best Practice User Guide

We can create guidelines for you on how to create Well Barrier Schematics in your company. This can be done both for clients using our Wellbarrier Illustration Tool and others. This will often serve as part of the company's internal management system and establish firm guidelines on how to prepare this in a consistent manner, through use of illustration principles, well folder structure, naming convention etc.

Well specific evaluations

If you have a well integrity issue with your well, we can assist you with evaluation of the defined well barrier solution in view of regulatory requirements and compliance with the two barrier principle. We can also include a qualitative risk assessment of potential leak paths, assessment of material selection, qualification and monitoring of the well barriers.

Evaluation of new technology

If you plan to develop or use new technology in a well, we can analyze your concept and advice you what effect this may have of the definition of well barriers, their qualification and monitoring requirements as defined by the NORSOK D-010 rev. 3 standard. Our confidential report includes a gap analysis with regulatory requirements (Norway) with recommendations of matters to be implemented and observations for consideration.

Well Integrity

Learn about the two barrier philosophy

The Wellbarrier software incorporates the barrier definitions that embrace the two-barrier principle as a core component of establishing well barriers.

The importance of having control of the safety in the wells cannot be underestimated. Several regulatory bodies and industry standards recommends that two independent barrier shall be in place, and that Well Barrier Schematics should be used to demonstrate this. Take a look at the video and get an easy to understand principle description of how to follow a two barrier philosophy.
