Trends in oil producing countries for well P&A and decommissioning

Abstract

Technological and financial issues associated with decommissioning and well plug and abandonment （P&A）in petroleum development are the focus of growing concern in petroleum development fields owned by Japanese E&P（Exploration & Production）companies.

Therefore, multiple petroleum development fields owned by Japanese E&P companies demanded to survey the trends of technological issues regarding decommissioning and well P&A, then a survey of the latest technological trends （"Trend Survey on Decommissioning and Well Abandonment"）was conducted in 2016.

The survey was contracted to and performed by the Xodus Group in UK.

The survey covered various topics such as decommissioning and well P&A technologies; equipment disposal methods; costs, laws and regulations; health, safety and environment（HSE）; stakeholders; and decommissioning/well P&A follow-up.
