Task summary
Task summary
This task will compile wellbore data and integrate it with confining system and reservoir maps to develop a tool to identify wells with leakage risks. The task includes three subtasks: development of wellbore database, development of wellbore integrity and screening tool, and development of guidance for CO2 storage scenarios.
Michigan has almost 95,000 individual boreholes drilled during oil, gas, mineral exploration, and development operations (map to the left). The oldest wells date back to the 1880s with many having poor records and documentation. Factors such as age, depth, and construction details are important in understanding potential for leakage through existing wellbores.
Develop wellbore database
Develop wellbore database
We will integrate well construction, plugging, and cementing information along with other relevant information such as lost circulation zones into a comprehensive database. The database will be used to generate a series of maps showing important wellbore information across the state
Wellbore integrity and screening tool
Wellbore integrity and screening tool
We will integrate all tasks and subtasks to develop an interactive tool, useful for regulators and operators, to evaluate wellbore integrity risk and identify high risk wells within specific sites and overlay societal considerations. The tool will be tested on identified regions.
Guidance document for CO2 storage scenarios
Guidance document for CO2 storage scenarios
The Recipient will develop guidance for remediation for different scenarios to inform operators and ensure the safe and long-term storage of CO2. Guidance will be implemented on selected sites to demonstrate its applicability.
