Project Description

The objective of this effort is to assess the factors influencing effective CO2 storage capacity and injectivity in the Marcellus shale, the Utica shale, including equivalent shales in Vermont; and the Devonian Ohio shale. The work addresses “approaches and/or technologies to improve injectivity and utilization of pore space.” Specifically, it provides a better understanding of CO2 trapping mechanisms leading to improved storage permanence and capacity estimates in gas shales, and the effects on storage and injectivity given variable gas shale reservoir types, rock properties, and stratigraphic and structural properties. This effort builds on previous efforts, primarily in New York and Kentucky, to assess the CO2 storage potential of gas shales. The primary focus is on establishing the reservoir engineering and operational requirements to overcome the constraints imposed by shale reservoirs to achieve cost-effective CO2 storage. In other words, the goal of effort is not just to answer “how much CO2 can be stored in gas shales”, but “what are the critical factors that can influence optimum CO2 storage volumes and injection rates in gas shales.”

Project Benefits

The project assesses factors influencing effective CO2 storage capacity and injectivity in organic shale formations to better understand CO2 trapping mechanisms, storage permanence, and capacity estimates in gas shales by developing and validating improved shale-formation models and monitoring techniques.
