Short summary
Low permeability sediments and rock can leak slowly, yet can act as important barriers to flow for resource development and for waste sequestration. Relatively rapid and reliable hydraulic tests of "tight" geological materials are possible by accelerating gravity. Results from geotechnical centrifuge testing of drill core and in situ pore pressure monitoring were compared with a regional flow model, and considered in the context of inherent geological variability at site and formation scale.
