Invitation to Tender for Carbon Storage Well Integrity Risk Screening Project

The objective of the project is to develop a robust understanding of the risk of loss of containment from existing legacy wells to help to mature the technical risk assessment process relating to these wells from a carbon storage perspective. Identifying a detailed methodology for screening will enable a consistent view on well integrity to be gained across those areas of the UKCS that are considered key to the successful development and deployment of carbon storage sites. The project will focus on developing an appropriate methodology for assessing the containment risk and leakage potential from legacy wells. The aim is to demonstrate the applicability of the methodology, the robustness of the screening and to present key findings from a selected subset of wells; this should subsequently enable the methodology to be applied to a wider range of wells in those areas of the UKCS currently identified to have the most potential for carbon storage and later extending to other areas as the OGA's evaluation of potential stores matures. The project will enable the OGA to expand its understanding of well integrity in support of the any future carbon storage licensing strategy and the ongoing stewardship of existing carbon storage licences.
