Mesoscale Deformational Features Near Outcrop Analogs Of A Reservoir-Seal Interface: Implications For Seal Failure, Santiago L. Flores

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The boundary that separates reservoir rocks from caprock seals is generally considered a flow barrier for reservoir fluids. Buoyant fluids do no flow through the caprocks because they have low permeability and molecular forces at the base of the caprock resist upward flow. Deformation at the reservoir/caprock boundary may include fractures that increase permeability and lessen the effect of the molecular forces.

The injection and storage of carbon dioxide (CO₂) in porous sandstone with effective top seals below earth’s surface is a possible solution for reducing the amount of human-created CO₂ in the atmosphere. Uplift and erosion …
