Direct-Sensing Technologies
The Hydraulic Profiling Tool (HPT) and Electrical Conductivity (EC) can be run as standalone tools or in combination on any direct-sensing tool string. These tools provide high density geologic and hydrogeologic data sets to help define subsurface geologic conditions.
​
-
The EC probe works by sending current through the formation between two probe contacts and defines lithology based on bulk grain size measurements.
​
-
The HPT probe uses a downhole transducer to measure the pressure response of soil to the injection of water that provides real-time profiles of soil permeability.
​​
Real-Time Data: Direct-sensing data allows for “in-field” decision making.
High Production Rates: Daily production rates >200’ per day.
Flexible: Can be operated out of a variety of vehicles: support trucks, off-road Gator or limited access cart or off the direct-push unit itself.
Proven Technology: HPT is manufactured and supported by Geoprobe Systems.
NO IDW: No soil cuttings, no purge water.
The Membrane Interface Probe (MIP) coupled with the Hydraulic Profiling Tool (HPT) is a semi-quantitative screening tool that measures volatile organic compounds (halogen and non-halogen) in the subsurface. It is the industry's best tool for collecting high resolution Volatile Organic Compound (VOC) contaminant and geologic data in real-time!

Optical Image Profiler (OIP)
The Optical Image Profiler (OIP & OIP-G) provides a detailed log of induced fluorescence of residual and free-phase NAPLs in the subsurface.
​
-
A UV LED (275 nm) source is used on the standard OIP probe and is tuned specifically for hydrocarbon fuels including gasoline, diesel, jet fuel, motor, hydraulic and cutting oil.
​​
-
A green wavelength (520 nm) source is used on the OIP-G probe and is tuned for heavier fuels including creosote, coal tars, and heavy fuels oils.
