Project Description

The project focuses on the development of engineering strategies/approaches for managing changes in formation pressure by testing active brine extraction wells, passive pressure relief wells, and combinations of both, to control the pressure buildup in a formation resulting from carbon storage activities. Under each pressure management strategy, a complete life-cycle analysis for brine is being developed along with brine handling strategies. The study includes some lab and pre-pilot scale work to obtain the design parameters for a second field testing phase. These approaches are going to be validated during the second phase effort that is taking place at the University of Texas at Austin’s Devine Test Site (Figure 1).

Project Benefits

This work is central to the Department of Energy’s goal of improving CO2 storage efficiency while ensuring containment effectiveness. Detailed implementation and monitoring design investigated in the first phase and consequent deployment of the outcomes during the second phase will increase the understanding and usefulness of pressure management and plume control technologies. Results of this project would alleviate concerns by industry and other end-users regarding the inadequacy of geological pore space to store large volumes of carbon dioxide. This project is providing more assurance to stakeholders that injection of large volumes of fluids for storage would not create excessive pressure regions with undesirable geomechanical and seismicity outcomes. In addition, integration of brine treatment technologies with brine extraction operations demonstrates the potential benefits of such projects to provide water resources for industrial, agricultural, and municipal usage. A key project outcome of the pretreatment and desalination effort is a techno-economic model that can be used for a wide variety of applications. The impact of this project enables economic large-scale extracted water recovery for CO2 sequestration.
