Geoprobe® Direct Image®

Direct Image® tooling systems vertically log in-situ soil characteristics such as:

  • lithology
  • electrical conductivity
  • permeability
  • VOC contaminant content
  • hydrocarbon fluorescence
  • various other geotechnical parameters

Geoprobe Direct Image Log

These logs can then be combined to create accurate, highly detailed conceptual site models…the critical first step in any site investigation. Our Direct Image® systems include MIP, MiHpt, LL MIP,  OIPHPTEC,  CPT, and PST.

Providing innovative technologies for the field of High Resolution Site Characterization (HRSC) for over 20 years.

Geoprobe Direct Image OIP

Image of hydrocarbon fluorescence in soil from the Geoprobe Optical Image Profiler (OIP).

New OIP System
March 14, 2016
Geoprobe Systems® is pleased to announce the release of its newest direct push logging technology; the Optical Image Profiler (OIP). The OIP is a powerful tool capable of detecting and logging UV induced hydrocarbon fluorescence in soil. View the introductory presentation below to see how this completely new concept in NAPL delineation technology works.

Evaluation and application of the optical image profiler (OIP)
May 17, 2018
The Geoprobe OIP team worked with consultants and regulators to write this peer reviewed publication about the new Optical Image Profiler that uses ultraviolet light (OIP-UV) to induce fluorescence of petroleum fuels (LNAPL) in the subsurface. The article provides information on design of the OIP-UV probe and system and how the down-hole CMOS camera provides images of insitu fluorescence and a log of fuel fluorescence as the probe is advanced. Results from OIP-UV investigation of 3 different sites and comparison to different methods (e.g. LIF) are reviewed.
