Abstract

A technique facilitates asset integrity management of underground storage assets, such as underground carbon dioxide storage sites. The technique comprises establishing a paradigm for asset integrity management comprising element fields related to elements such as asset life cycle, implementation procedures, technologies, tools, and methods to obtain and evaluate data, and control/mitigation measures. Data related to the element fields is processed based on relationships established by the paradigm. Based on the analysis, information related to the integrity of the underground storage asset is output lot-use in managing the underground storage asset.

Claims

determining relationships between elements of an underground storage asset to establish a paradigm for maintaining asset integrity;

obtaining data related to a life cycle element of an underground storage asset;

implementing a procedure element to govern management of the integrity of the underground storage asset;

utilizing a technology element to obtain and evaluate the data related to managing the integrity of the underground storage asset over time; and

processing the data according to a control clement to determine appropriate control measures for maintaining the integrity of the underground storage asset.

2. The method as recited in claim 1, wherein obtaining data comprises obtaining data for initial asset characterization of an underground carbon dioxide storage asset.

3. The method as recited in claim 2, wherein processing the data comprises evaluating the data to make a risk assessment as to the life cycle of the underground storage asset.

4. The method as recited in claim 2, wherein processing the data comprises analyzing the performance of the underground storage asset over time.

5. The method as recited in claim 2, wherein processing the data comprises analyzing the performance of the underground storage asset in terms of at least injectivity, capacity, and containment over time.
