Final Report: Depth-specific Hydraulic Testing of Yucca Flat and Frenchman Flat Environmental Restoration Wells, FY 2003
- Nevada Site Office, Las Vegas, NV (United States)
Borehole flow logging contributes a greater understanding of subsurface conditions than measuring well discharge only at land surface. Combining the results of up to nine borehole flow logs to estimate hydraulic conductivity with depth includes data averaging over vertical intervals and averaging of calculated hydraulic conductivities among the various flow logs. Data filtering is also necessary to aid in differentiating between changes in borehole flow rate due to flow turbulence (and other causes) and those associated with groundwater inflow. Borehole flow logging during well pumping has provided the quantity of groundwater iniflow and hydraulic conductivity at depth for three wells. The results provided are believed to be an appropriate balance between predictive accuracy and preserving spatial resolution.
