  • Equipped with a proven Geoprobe 142HP engine and hydraulic system that provided excellent climbing and turning ability
  • The robust track system of the 142-horsepower allows for CPT drilling in most terrains. It’s proven drive-train and chassis provide excellent climbing and turning ability
  • 20-tons of downforce, 30-tons of pull and 7 psi ground pressure
  • Undercarriage camera and climate controlled cabin
  • Four hydraulic outriggers and an auxiliary bottom clamp to secure the tool string with the push clamp is released 
  • Controls that make jobs in the field quick, efficient and comfortable 

COne Penetration testing (CPT)

CPT drilling determines subsurface stratigraphy, and estimates geotechnical parameters and materials present
  • Used by geotechnical engineers to determine construction requirements for infrastructure, roadbeds, bridges, and buildings
  • Common measurements being collected are cone tip pressure, sleeve friction, pore pressure, tilt angle – Seismic measurements also possible 
  • Independently gauged geotech AB cones deliver high resolutions digital data
  • Utilizes the in-situ measurement: measures soil properties in the right environment; in the soil as it is, where it is 
  • Real-time, repeatable and on-site interpretation of soil logs can be used to better identify the soil type, water table and soil parameters for engineering design ultimately saving project costs
  • Faster production rates when compared to conventional drilling and sampling result in a most cost-effective operations 

Membrane interface probe (MIP) (MIPHPT)

Log the relative concentration of volatile organic compounds with depth of soil
  • MIP is a logging tool that measures hydrocarbon and solvent contamination along with soil electrical conductance and permeability 
  • An inert carrier gas is continually swept behind a heated membrane in the probe, delivering it to a series of detectors at the surface. The detectors each respond to different analyte properties which allows the MIP operator to discern the contaminant to its family group as well as provide the ability to map out the contaminant plume from source to extent
  • Shows distribution and relative magnitude of both halogenated and non-halogenated VOC contaminants
  • Works in both saturated and unsaturated soils. Detects contaminates in both coarse and fine grained soils 
  • Real time contaminant screening information is generated, allowing field adjustment of the site investigation 

Hydraulic profiling Tool (HPT)

FEATURES
  •  Real-time profiling of soil hydraulic properties
  • Use in fine and coarse grain material 
  • Use in saturated and unsaturated conditions
  • Built to withstand percussion driving 
  • Provides a simultaneous log of electrical conductivity (EC)
  • Transducer measures pressure response of soil to injection of water
  • Data is stored on the field instrument for future analysis
BENEFITS
  • Select well screen intervals 
  • Establish hydraulic conductivity of groundwater on site
  • Measure static groundwater elevations across the site
  • Target zones for injection of remediation material 
  • Evaluate properties of unconsolidated materials 
  • Examine the electrical conductivity of so

Geoprobe™ NOVA CPT (Cone Penetrating Testing)

CPT FEATURES:

  • The only CPT probe industry-wide that provides a constant stream of real- time data while you’re probing … without a cord downhole.

  • The only data transmission system of its kind.

  • Operator does not have to manage data cable as the rods are cycled in and out of the sounding hole. Rod handling is efficient and the risk of cable damage is eliminated.

  • New, RW NOVA technology uses radio waves to transmit measurements back to the receiver, opening the door for cordless SCPT, downhole video camera capabilities, and other data collecting sensors.

  • Data transmission methods: Acoustic NOVA, Cable NOVA, RW NOVA

  • New cone design offers 18 bit resolution with improved strength and gauge measurement accuracy.

  • Repeatable penetration results

  • Rod bore can be used for lubrication grouting as rods are pushed into the ground and for retraction grouting as rods are retrieved

  • Can be used with multiple push platforms: drill rigs, cone trucks, Geoprobe® direct push machines.

  • Interpret results quickly with user-friendly CPT-PRO software for comprehensive data evaluation.

Geoprobe™ HPT (Hydraulic Profiling Tool)

The Hydraulic Profiling Tool (HPT) allows the user to create fast, continuous, real-time profiles of soil hydraulic properties in both fine- and coarse-grained material. The HPT uses a sensitive, downhole transducer to measure the pressure response of the soil to injection of water.

HPT FEATURES:

  • Fast, continuous, real-time profiling of soil hydraulic properties
  • Use in both fine- and coarse-grained material
  • Use in both saturated and unsaturated conditions
  • Built to withstand percussion driving
  • Collects static water level data
  • Provides a simultaneous log of electrical conductivity with integrated Wenner array
  • Sensitive downhole transducer measures pressure response of soil to injection of water
  • Parameters are displayed and stored on the Field Instrument for future analysis
  • Improved Overall
  • Equipment Effectiveness
  • Increased maintenance efficiency
  • Reduced scrap rates and Higher Product Quality
  • Greater process consistency
  • Better throughput, with zero machinery investment

Electrical Conductivity (EC) plots in mS/m
HPT pressure plots in psi

Plots of EC (left) and HPT pressure (right) collected concurrently. Both the HPT pressure and the EC data confirm that clays predominate the upper 20 feet, which is underlain by ~35 ft. of silts and sands, followed by ~10 ft. of clays. Static water level was calculated to be at 31 ft. The HPT log was made to characterize potential contaminant migration pathways at the site. The line drawn on the HPT pressure plot shows the hydrostatic increase as the probe gets deeper below the static water level.
