• Air-slug low-pressure straddle-packer system to facilitate characterization of fractured bedrock 

      Svenson, Erik; Schweisinger, T.; Murdoch, L.C. (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)
      Straddle-packer tests are used for determining aquifer properties in fractured rock, but packer tests are often avoided because they can be expensive. We have developed a simple, inexpensive, lightweight air-slug straddle ...
    • Transient changes in fracture aperture during hydraulic well tests in fractured gneiss 

      Schweisinger, Todd; Svenson, E.; Murdoch, L.C. (Georgia Institute of TechnologyInstitute of Ecology, The University of Georgia, 2005-04)
      The influence of deformable fractures on aquifer tests is studied by the development of a technique to measure and analyze in-situ changes in fracture aperture. A high-resolution borehole extensometer is used to measure ...
