  • Further analysis of the potential of NMR for characterization of unconsolidated aquifers: borehole versus laboratory measurements, Stanford University (July 1, 2014 - 2/1/2017)

    The nuclear magnetic resonance (NMR) technique has become popular in groundwater studies because it responds directly to the presence and mobility of water in a porous medium. In unconsolidated aquifers, attempts have been made in boreholes to establish the NMR-K relationship by acquiring NMR and hydraulic conductivity (K) data. However, it is challenging to obtain reliable estimates of the NMR parameters from such borehole data. Laboratory-NMR data could aid in development of NMR-K models, as is typically done in the petroleum industry. However, the challenge has been obtaining high-quality laboratory samples from unconsolidated aquifers.

    In this project, we presented a detailed comparison of laboratory- and borehole-NMR data under most-promising conditions at a study site in Denmark. We addressed the challenges facing both measurements, and proposed methodologies to overcome those challenges. An excellent agreement is observed between the laboratory- and borehole-NMR data and a strong correlation is found between the observed and predicted K.

  • Aquifer characterization in the Indian Wells Valley, California using geophysical techniques, Stanford University (October 1, 2015 - October 1, 2016)

    In partnership with the Indian Wells Valley Water District, the town of Ridgecrest, and the China Lake Naval Air Weapons Station (NAWS), the GEM center undertook a pilot study in May 2016 to assess the combined use of TEM, surface nuclear magnetic resonance (NMR) and logging NMR to characterize a complex fresh/brackish aquifer system in their groundwater basin. In an effort to attain sustainable management, stakeholders are considering using brackish water from the lower portion of the aquifer system. Results of this pilot study indicate that TEM is viable across the varied geologic environments of this basin, providing clear indications of the water table, differentiating coarse sediments from silts/clays, identifying the transition to bedrock, and providing indications of increasing groundwater salinity in some areas. Downhole NMR proved to be a valuable tool to control and refine the TEM inversion in areas with appropriate wells for logging. Surface results suggest that this tool would be well applied in the portion of the NAWS where the water table is shallow and drilling is precluded due to base activities.
