Oil and gas companies in Alberta are responsible for ensuring their infrastructure is safely closed and cleaned up. The costs associated with this closure work – also known as end-of-life obligations – are what's called “liability.” At the end of 2020, the total liability for Alberta's oil and gas sector was approximately $30 billion. This liability information can be found on our Liability Management Rating and Reporting page.

The Government of Alberta sets policy direction for how liability is managed and provides general oversight with the ultimate goal of reclaiming land for other uses. The AER is responsible for implementing policy, monitoring progress, and providing enforcement when needed. Our mandate is to protect public safety and the environment while ensuring responsible energy development.

Liability management has been a growing area of public concern in recent years in Alberta, as well as other jurisdictions. Through ongoing consultation with industry and other stakeholders, the Government of Alberta and the AER have identified gaps in how liability is managed in the province.

What needs to change

Liability management aims to reduce the number of inactive wells over time. These are wells that haven't produced and have been idle for 6 or 12 months based on the well classification. However, closure work has not kept pace with the steady growth of the number of inactive wells. While the recent economic downturn has played a factor, even during times of prosperity, the amount of closure work has often lagged behind. There were approximately 97 000 inactive wells in the province at the end of 2020, up from 89 000 in 2019, and 84 000 in 2018.

It is clear that how we manage liability has not slowed the growth of inactive wells. Historically, liability management has been largely reactive and not focussed on the full life cycle of energy development. In particular, the liability management rating (LMR), which is a rating based on a company's liabilities and assets, is not an accurate measure of whether a company will be able to address their end-of-life obligations.

A company with an LMR of 1.0 – meaning they have the same amount of assets as liabilities – avoids having to post security for future closure work. When a company has more liabilities than assets, their rating would then drop below 1.0, and we would focus on collecting security. At this point it is often too late in the life cycle to collect security because the company may already be in financial distress. Some companies that are in distress eventually become insolvent, and some of their liabilities could ultimately be managed by the industry-funded Orphan Well Association (OWA).

We have seen companies become insolvent with ratings above 2.0, and some as high as 30, which highlights the need for change. With this, a more holistic review—aside from mere information on assets and liabilities—is needed to assess whether companies can meet their regulatory and liability obligations and safely clean up their sites.

New liability management framework

In July 2020, after consultation with the AER, industry, and other stakeholders, the Government of Alberta announced a new liability management framework consisting of five new policy components. We have been directed to create new programs to support the implementation of this framework, which aims to improve liability management in the province by taking into account the full life cycle of energy development.

The following video provides an overview of the new liability management framework, and introduces the new licensee capability assessment.

The licensee capability assessment is a holistic evaluation of licensees throughout the energy development life cycle and will replace the licensee liability rating (LLR) program. The evaluation will include looking at more information than strictly liabilities versus assets. The new assessment will look at a company's financial capability, along with their closure, administrative, operational, and compliance history. The initial focus will be on the oil and gas sector. The AER expects to have more information about the implementation of the licensee capability assessment by mid-2021.

The AER will proactively assess licensees – including those that are distressed – to ensure they are addressing their regulatory and liability obligations throughout the entire life cycle of energy development. We will consider information gathered from the licensee capability assessment and use regulatory intervention if needed.

The inventory reduction program will introduce mandatory spend targets for closure work.

Voluntary spend targets for closure work will continue through the area-based closure program. Another piece of this program will create a process where landowners and other eligible requestors may nominate inactive or abandoned wells and facilities for closure work through an ‘opt-in' process.

The Government of Alberta will explore this issue with a panel of experts and identify potential solutions and funding options for legacy and post-closure site stewardship. Legacy sites were abandoned, remediated, or reclaimed before current requirements were introduced. Post-closure sites have received reclamation certificates and the operator's liability period has lapsed.


Bill 12:The Liabilities Management Statutes Amendment Act, which came into effect on June 15, 2020, enables the OWA to better manage and accelerate the clean-up of sites that do not have a responsible owner. The most notable changes include the following:

  • The OWA may provide care for sites when a licensee is unable to provide ongoing reasonable care and implement measures to prevent impairment or damage to their assets.
  • The OWA may manage, maintain, operate, and sell assets for potential transition to a new responsible party.
  • The OWA may now appoint a receiver in insolvency to offset remaining liabilities when productive assets can be assumed by new responsible parties.

    New full-life-cycle approach

    The AER is committed to building programs, systems, and processes to help industry reduce liability in the oil and gas sector. We will do this through a holistic approach that applies at all different phases of energy development – rather than focusing late in the life cycle. Liability management programs that apply throughout the entire life cycle of development will allow us to proactively identify potential issues, develop timely solutions, and increase the amount of closure work done by companies.

    This graphic outlines when the new programs will be involved during the life cycle of energy development.

    Full Lifecycle Approach


    Regulatory Changes

    Before we can implement the new government policy, changes are required to several AER directives. We have also announced updates to the Oil and Gas Conservation Rules and Pipeline Rules. We want to ensure that all Albertans have a chance to review potential directive changes through our public feedback process. Alberta needs these changes now. You'll see a lot of information from the AER over the next few months, including opportunities to provide input, as we work to build our liability programs.

    Important dates

    This section will be updated as we build and implement the new programs and post new information. As we work through these changes, opportunities for public feedback will be posted below. We will also be meeting with industry to outline the new programs and help stakeholders to understand how the changes will impact them.

    Other AER liability initiatives

    Area-based closure program

    The voluntary area-based closure (ABC) program encourages oil and gas companies to work together to decommission, remediate, and reclaim their energy infrastructure and sites. Participants can complete more closure work for the same cost by collaborating with other companies. They benefit by sharing information, services, and infrastructure with other companies and service providers that are completing closure work in the same area. Through the voluntary program, more than $340 million was spent on closure work across the province in 2019. More information can be found in the 2019 ABC highlights report.

    The ABC program was developed by the Alberta Energy Regulator, the Canadian Association of Petroleum Producers, the Explorers and Producers Association of Canada, and the Petroleum Services Association of Canada.

    Other liability initiatives not involving the AER

    Site Rehabilitation Program

    The Government of Alberta's site rehabilitation programis funded by the Government of Canada and allows eligible companies to apply for funding to complete abandonment and reclamation work. The Government of Alberta is responsible for awarding and distributing program funds. The program is not part of the new liability management framework and the AER is not involved in its administration.

    However, companies participating in the program must continue to meet all AER requirements. Albertans can contact the AER's 24-hour response line at 1-800-222-6514 if they have any safety or compliance concerns.

    More information about eligibility, project requirements, and detailed guidelines can be found on the Government of Alberta's site rehabilitation program website. Questions about the program should be directed to the Government of Alberta at 1-833-680-9083 or @email



    We know that Albertans are passionate about liability. If you have a question about a certain program, please connect with us.

    Project Closure

    The AER requires licensees to meet closure requirements when an oil and gas site is at the end of its lifecycle. These requirements include abandonment, reclamation, and remediation. Our video series helps explain the process a well goes through when it is finished producing oil and gas.

    The Redwater Decision

    In January 2019, the Supreme Court of Canada overturned the Redwater Decision, determining that receivers and trustees of insolvent oil and gas companies cannot avoid end-of-life obligations. The ruling means these obligations must be addressed before creditors are repaid.

    We are working with insolvency professionals and we recognize their role in helping to ensure that end-of-life obligations are addressed. Insolvency professionals play an important role in marketing energy assets, and in doing so helping reduce liabilities.

    We will not object to insolvency professionals receiving appropriate fees during the insolvency process.

    More information about the Redwater decision can be found here.

    AER's role in insolvencies

    The AER does not control or prevent insolvencies. Our main focus when a company enters into insolvency is to protect the public and the environment. During the insolvency, the AER will work with the licensee, or appointed insolvency professional, to address remaining end of life obligations. These obligations can be addressed in several ways, such as transferring licences to responsible licensees, completing closure work, or the posting of security.

    The AER encourages insolvency professionals to seek early feedback from us on regulatory issues regarding potential licence transfers. When assets are sold, a transfer application must be submitted to us for approval. Our final decision ensures that the purchaser is an eligible licensee and that the application meets all requirements.

    When there is inventory that has not been sold or transferred to responsible operators and there are no industry partners to hold responsible for closure work, we will work to ensure that any remaining funds in the estate are used for site cleanup by the OWA.

    Orphan Well Association

    When there is no legally responsible party to look after an asset, the AER may designate it as an orphan. The responsibility for an orphaned asset is then transferred to the Orphan Well Association (OWA).

    The OWA is an industry-funded, not-for-profit organization. The OWA's annual budget is paid by oil and gas operators through the orphan fund levy. The AER collects the funds from operators and transfers them to the OWA. The 2020 orphan levy amount is $65 million—an increase of $5 million from 2019.

    In May 2017, the Government of Alberta provided a loan of $235 million to the OWA to help address a backlog of orphaned sites. The interest on the loan is being covered by a $30 million grant from the Government of Canada. This loan was extended by up to $100 million in March 2020. A portion of past and future orphan fund levies will be used to repay the loan. In April 2020, the Government of Canada provided a separate $200 million loan to the OWA.

    Unpaid Surface lease payments

    The AER is not involved with surface lease payments. Landowners should contact the Surface Rights Board at 780-427-2444 or @email for information or questions about surface lease payments. Landowners are eligible to apply for surface lease compensation through the Surface Rights Board.

    The Government of Alberta has more information on what to do when a company fails to make annual surface lease payments.

    The Farmers' Advocate Office provides support and resources for farmers and ranchers, including advocacy and energy, utility, surface rights, and rural dispute resolution. You can contact the Farmers' Advocate Office through 310-FARM (3276) or @email.

    Unpaid municipal taxes

    Some oil and gas companies are walking away from their end-of-life obligations and their duties to pay surface lease agreements and municipal taxes where they operate. In January 2020, the Rural Municipalities of Alberta estimated that its members are owed more than $173 million from the energy sector.

    The AER is not involved with municipal taxes and does not have jurisdiction to impose licence conditions on oil and gas licensees that have unpaid municipal taxes.
