Applicability of Analytical Models to Single-Well Permeability Tests in Deep and Hydraulically Tight Geological Formations

Abstract

In situ permeability tests are crucial in hydraulic characterizations of geological formations for the disposal of radioactive nuclear waste. As has been done in most countries where geological disposal of high-level radioactive wastes has been discussed, single-well permeability tests are generally conducted in a preliminary stage of selecting a site where groundwater exists. To determine accurately hydraulic parameters, specifically hydraulic conductivity and specific storage, from single-well permeability tests, it is worth reexamining analytical solutions for modeling test data derived from deep and hydraulically tight (hydraulic conductivity is typically less than
