Energy: Plug And Abandonment
Plug & Abandonment (P&A) in the Drilling & Oil & Gas Industry refers to the process to:
- Permanently seal & isolate a well that is no longer productive & needed
- Ensure there is no environmental risk
P&A is usually performed when a well has reached the end of its economic life, is dry & no longer viable for production & exploration.
P&A Process:
- Well preparation: The well is cleaned & all production equipment is removed
- Plugging: Cement plugging equipment is installed at a specific depth to seal the wellbore & prevent fluid migration & hydrocarbon leakage to the surface or between underground formations
- Casing management: Sections of the well casing may be cut & removed, or left in place, depending on regulations
- Surface restoration: The wellhead is removed & the site is returned to its natural state or reused
P&A is essential for:
- Environmental protection
- Preventing groundwater contamination
- Complying with regulations
P&A is a complex & expensive process that demands precision to ensure long-term safety & integrity.
