What is Plug and Abandonment and Why is it Important?

“Plug and Abandonment” refers to the process of permanently sealing an oil or gas well that is no longer productive or economically viable. When a well reaches the end of its operational life, or if it becomes unsafe or uneconomical to continue production, it needs to be properly closed off to prevent any potential environmental or safety hazards.

The Plug and Abandonment process typically involves several steps, including the retrieval of production equipment from the well, removal of wellhead and associated infrastructure, and the placement of cement plugs at various depths within the wellbore to isolate and seal off different zones. The well is then capped with a permanent seal or a device called a wellhead plug to prevent the migration of fluids or gases between different geological formations.

The importance of Plug and Abandonment in the oil and gas industry can be attributed to several reasons:

Environmental Protection

Properly plugging and abandoning wells is crucial for safeguarding the environment. Abandoned wells that are not sealed can potentially leak hydrocarbons, brine water or other harmful substances into groundwater or surface water, leading to contamination and ecological damage. By conducting effective Plug and Abandonment operations, the industry aims to minimize the risk of such incidents and protect the environment.

Safety and Risk Mitigation

Abandoned wells that are not properly plugged can pose safety risks, such as the uncontrolled release of hydrocarbons or the potential for blowouts. These situations can result in explosions, fires and other hazards. By performing Plug and Abandonment activities, the industry mitigates these risks and ensures the safety of workers, nearby communities and infrastructure.

Regulatory Compliance

Governments and regulatory agencies impose strict regulations and guidelines regarding the abandonment of wells. Oil and gas companies are required to adhere to these regulations to maintain compliance and avoid legal consequences or penalties. By conducting Plug and Abandonment operations in accordance with the regulatory framework, companies demonstrate their commitment to responsible resource extraction and environmental stewardship.

Asset Retirement and Financial Responsibility

Plug and Abandonment is a critical component of the overall lifecycle management of oil and gas assets. By properly plugging and abandoning non-producing wells, companies can retire unproductive assets and allocate resources more efficiently. This process also involves estimating and setting aside financial provisions for future Plug and Abandonment activities, ensuring that the costs associated with decommissioning and environmental remediation are adequately covered.

Plug and Abandonment Frequently Asked Questions (FAQs)

Why is Plug and Abandonment necessary?

Abandoned oil and gas wells that have not been sealed securely can pose a variety of environmental and health hazards. Degrading cement and steel that compose wellbores can lead to migration of gases or fluids, which can contaminate surface water or groundwater, and in some cases, accumulations of gases can lead to explosion risks. These hazards become more likely if unsealed wells are near oil and gas enhancement operations utilizing hydraulic fracturing. Unsecured wells may also pose a danger to human health through emissions of air pollutants such as benzene, hydrogen sulfide or volatile organic compounds (VOC).

What is the process of Plug and Abandonment?

When decommissioning oil and gas wells, there are several steps involved. First, the condition of the well is assessed, including the underground casing and cement, to identify any leaks or dangers below the surface. Then, the wellbore is cleaned and sealed using cement or other materials. The extent of sealing depends on the conditions underground and regulatory requirements. Finally, the equipment on the surface is taken away, and the area around the well is restored following reclamation standards.

How much does Plug and Abandonment cost?

The cost of Plug and Abandonment operations depends on key factors and well characteristics: well type (oil or gas), age, depth, complexity (laterals and number of completions), location and regulatory requirements. In 2021, an industry research group put the median cost for decommissioning a well in the U.S. at approximately $20,000 for plugging and $76,000 for plugging and surface reclamation. They further found that for each additional 1,000 feet of well depth, the cost increased by 20%, and that older wells are more costly than newer ones. Natural gas wells are 9% more expensive than oil wells, with costs varying widely by state. Research also found that surface characteristics around the well substantially affect operational costs. Each additional 10 feet of elevation in a 5-acre area surrounding wells raises costs by 3%. On the plus side, this research also showed that operators who arranged contracts with services companies to perform Plug and Abandonment operations on collective assets reduced their decommissioning costs by 3% per well.

Who is responsible for Plug and Abandonment?

According to the Code of Federal Regulations under Title 30, lessees, owners of operating rights, and their predecessors are jointly and severally liable for meeting decommissioning obligations for facilities on leases, including the obligations related to lease-term pipelines, as the obligations accrue and until each obligation is met. To further clarify this part of Title 30, lessees and the owners of operating rights include two stakeholders: those that have paid for the right to develop oil and gas wellsites and those operators who have drilled and completed wells. And, because these parties are subject to change, decommissioning obligations can revert in part to a party or parties that held interest in a well prior to those who currently hold or were the last to hold interest in a well.

What are the environmental considerations in Plug and Abandonment?

Abandoned wells are a danger to health because they can contaminate groundwater, making the water unsafe to drink. This contamination includes harmful substances like benzene, which can cause diseases like aplastic anemia and leukemia. Additionally, these wells release methane, a potent greenhouse gas approximately 25-84 times more effective at trapping heat in the atmosphere than carbon dioxide over a 20-year period. The large-scale emission of methane from abandoned wells poses a serious threat to our climate and sustainable economic growth. When oil and gas wells are not correctly closed down, they keep releasing methane into the air and pollute the groundwater that local communities depend on for clean drinking water.
