Description

Storage or disposal of fluids such as carbon dioxide, wastewater, or hydrogen in the subsurface can result in chemical disequilibrium between the resident brine and the formation. In this presentation I explore how chemical change can enhance or inhibit fracture growth, and how such processes can affect shale caprock integrity of storage reservoirs.
