IOGP Report 676 - Well abandonment and integrity evaluation for CO2 storage
One of the challenges in CCS projects is to ensure that the carbon dioxide (CO2) remains in the intended storage reservoir. There are numerous potential leak paths in a storage reservoir. The leak paths could be either natural (pre-existing faults, fractures, insufficient caprock integrity), or fabricated (induced seismicity and artificial penetrations such as underground mines and wellbores). CO2 storage can be achieved with negligible impact on the environment when potential issues with leak paths, such as wellbores, are sufficiently identified and managed. Wells are designed and constructed with barriers to prevent fluid migration throughout the expected lifecycle, including decommissioning. However, there is a need for guidance to address the well integrity evaluation for both project and legacy wells as well as future abandonment of existing CCS project wells.
This document provides guidelines and considerations for well plugging and abandonment (P&A) approaches of both project and legacy wells within a carbon dioxide (CO2) geologic storage site. This includes well integrity evaluation methods, barrier philosophy, and plugging materials such as cement or alternatives.
This document is intended for wells personnel and industry stakeholders who are involved in a CCS project, specifically in the evaluation, planning, and execution phases.
