Project Description

Oak Ridge National Laboratory (ORNL), Ohio State University (OSU), the University of Tennessee at Knoxville (UTK), and XCEL Engineering staff are collaborating through this project to enhance and integrate the use of tracer and isotope methods in order to improve understanding and predictions of CO2 plume migration in the subsurface (Figure 1). The overall goal of this effort is to provide methods to interrogate the subsurface that will allow direct improvement of CO2 storage in saline formations or during enhanced oil recovery (EOR), enhanced coal bed methane (ECBM) recovery, and enhanced gas recovery (EGR). This will be accomplished through the following three technical tasks:

Task 1 – Transfer of perfluorocarbon tracer (PFT) and isotopic geochemistry technology to partners for collaboration and deployment of MVA techniques. (read more)
Task 2 – Evaluate effects of hydrocarbon-rich matrices on PFT capture and quantification in gas samples. (read more)
Task 3 – Improve quantitative models of CO2 plume activity in reservoirs using perfluorocarbon and geochemical tracer data in new simulator modules. (read more)

Project Benefits

This work directly addresses the objective of the Storage Program to increase confidence in and the safety of geologic storage by identifying and demonstrating cost-effective and innovative monitoring technologies to track migration of CO2 and its reaction products in geologic formations.
