“…Also, a brief discussion is given on the joint use of complimentary methods. This paper does not specifically discuss borehole geophysics, including single-well geophysical borehole logging (e.g., Dalan and Goodman, 2007) or cross-borehole tomography (Paillet and Ellefsen, 2005).…”

“…Near surface invasive sensors, e.g., geophysical logging tools operated in boreholes reaching depths of 30 m or less, probe very limited volumes with lateral penetration depths of a few centimeters to maximally a few decimeters (e.g., Paillet and Ellefsen, 2005). The classical borehole installation procedure in unconsolidated sediments usually requires the drilling with a larger diameter than the finally installed casing required to hold the borehole open (e.g., Aller et al, 1991).…”

“…The crosswell radar method is used to image heterogeneity between wells in the ground (Paillet and Ellefsen, 2005). A straightforward way to assess the accuracy of an image is to compare it to the in place heterogeneity.…”

AbstractCrosswell radar data were collected among three wells in a laboratory tank filled with dry sand. Embedded within the sand was a long plastic box, which was the target for the data collection. Two datasets were collected between each pair of wells, making a total of six datasets. The frequencies in the data ranged from 0.5 to 1.5 gigahertz, and the peak frequency was 0.9 gigahertz. The data are well suited for evaluating various processing algorithms, and the data linearly scale to typical field conditions.
