Integrated Subsurface Evaluation

Hydrophysical Logging Summary

  • The technique is applicable in a wide variety of hydrogeologic settings: low to high yield bedrock, alluvial/porous settings, karst and volcanic aquifers.
  • Both open boreholes and completed wells can be characterized (2 inch minimum diameter).
  • Water bearing intervals are identified to within one borehole diameter resolution.
  • A wide range of interval specific flow rates can be quantified (0.01 to 100+ gpm).
  • Flow rates can be assessed independently of borehole diameter.
  • Wellbore flow can be evaluated under ambient or stressed aquifer conditions.
  • A larger volume of the aquifer is investigated than by traditional packer testing and is more time and cost effective than packer testing.
  • Interval specific water quality can be evaluated.
  • Single and cross-hole aquifer characterization (i.e. evaluate larger scale hydraulic connections between two or more wells) can be accomplished.
  • Data output equivalent to packer testing for transmissivity and hydraulic conductivity calculations.
