Abstract: The focus of this research is the use of nuclear magnetic resonance (NMR) logging as a\r\nmeans of determining the hydraulic conductivity of a glacial aquifer. Compared to other field approaches, NMR logging has important advantages: it can be performed rapidly and allows for high-resolution characterization along a vertical profile, does not require that the well be screened over the test interval, and should not be affected by insufficient well development. NMR logging has been used since the 1960s in the petroleum industry, but only recently for groundwater applications with the development of a tool specifically designed for small-diameter wells.
