Well integrity assessment of the P18 gas field (TAQA)

CO2 storage is being considered in TAQA’s P18 gas field. In the context of the CATO-2 project the suitability of the existing wells in the field is being investigated for injection and long-term storage of CO2. The well integrity assessment covers the operational phase of the injection project (decades) and the long-term post-abandonment phase. The study aims at the evaluation of the relevant well system barriers to identify potential showstoppers and recommendations on remedial actions and abandonment strategies. This report presents progress until September 2011, but does not describe the final conclusions of the well integrity assessment of the P18 field.
