Plug and Abandonment (P&A)

Plug and Abandonment (P&A) of a well involves plugging back a wellbore and temporarily securing it for a few months to years or permanently with an eternal perspective in mind.

• In most areas, the retirement of assets is outlined by the national regulatory agency. The primary objective is to ensure that no leaks to surface exist and that no formation fluid migration occurs even many years after the well has been abandoned.
  
  
  

• In places where no national regulations exist, oil companies typically implement their own standard procedures for how to safely plug back a well.
  
  

• Plugging back a well is a standard operation in the life cycle of a well that all oil companies address when the well is no longer useful or becomes unprofitable. This is not an operation that generates revenue and is purely an added expense that must be completed as quickly and cheaply as possible while adhering to regulatory guidelines.
  
  

• Older wells often suffer from annular leaks or a loss of casing integrity that can further complicate the p&a operation. These cases often require the operator to cut and pull tubulars or section mill casing in order to gain access to the leaking interval and seal it off.
  
  

• ENERSOL utilizes our technology, equipment and expertise to provide tailor-made abandonment solutions that permanently isolate the reservoir and abandon the well, focusing on regulatory requirements, cost minimization and operational efficiency.
  
  

• ENERSOL delivers the expertise required to safely and efficiently meet your abandonment needs, both onshore and offshore. Our solutions will ensure your project stays on track and under budget. Enersol provides expert pipe cutting, milling and fishing services for wireline, coiled tubing and pipe conveyed applications.
