A Trillion Dollar Problem​

Today’s energy sector faces a daunting number of inactive, unplugged non-producing wells along with their associated facilities, presenting a trillion-dollar problem for the industry, its investors and stakeholders—and ultimately the U.S. taxpayer. Posing significant environmental risks as sources of methane emissions and groundwater contamination, the impacts of these unplugged wells will continue to grow in magnitude if not addressed. Tackling this issue is an important step toward meeting global greenhouse gas reduction goals.

What is an Asset Retirement Obligation (ARO)?

An ARO is the legal liability that a company carries on its balance sheet to cover the costs of retiring an asset. In an oil and gas asset, this includes decommissioning the well by properly plugging it downhole, removing surface equipment, and reclaiming the surface area back to its natural state or as regulatory agencies require.

We ensure the proper plugging of oil and gas wells, facility decommissioning, and surface restoration through our suite of pre-need solutions. We combine data science, operational expertise, and an innovative insurance-based funding structure that helps energy companies manage decommissioning costs while ensuring operational excellence.

Climate and ESG​

Responsibility does not end when assets stop producing

Asset retirement planning is essential to Corporate Social Responsibility (CSR), Environmental Social and Governance (ESG), and Responsibly Sourced Gas (RSG) strategy.

Orphan wells and stranded assets cause dangers to the environment including emissions of greenhouse gases like carbon dioxide (CO2) and methane (CH4) which impact climate change. While the significance of the impact of orphan well has yet to be fully measured, we know that long-term idle wells lead to orphan wells. This means that asset retirement planning is critical to preventing future orphaned wells.

OneNexus Assurance represents a financial commitment to eliminate dangers and provide a full cleanup of an oil and gas asset at the end of its useful life. It guarantees that a company has planned for and committed to the use of best practices in plugging a well and the timely removal of all hazards that may cause harm to the environment or human life.
