Project Description

The objective of the project is to develop and apply a universal methodology for estimating the carbon balance of a carbon dioxide (CO2) enhanced oil recovery (CO2-EOR) operation and to make the determination of whether the operation can attain Net Carbon Negative Oil (NCNO). The project team will identify and frame critical carbon balance components for the accurate mass accounting of a CO2-EOR operation and develop strategies that are conducive to achieving a NCNO classification. In addition, the researchers will consider energy intensive components of the operation not typically included in carbon life cycle analyses and similar studies, such as compression and fluid handling. The team has selected the Cranfield site in Mississippi (an active CO2-EOR field) as the ideal case study field.

Project Benefits

This project is focused on developing and applying a universal methodology for estimating the carbon balance of a CO2‐EOR operation. Increased understanding of the carbon balance as related to CO2-EOR operations willpr improve operational effectiveness and optimize CO2 storage capacity. Specifically, the overarching objective of the project is making the determination of whether the operation can be classified as NCNO. The developed methodology will be clear, comprehensive, repeatable and widely applicable to CO2-EOR scenarios. As the carbon balance of an EOR operation depends significantly on the volumes of CO2 ultimately stored in the formation, a variety of different CO2 injection scenarios will be considered.
