Preparing the 2060CPT for CPT testing.

The 20 CPT Press from Geoprobe® is a flexible mast option with a 20-ton capacity, designed specifically for performing cone penetration tests. Its quick mount design allows for attaching the CPT mast to multiple platforms, including the Geoprobe® 6712DT Direct Push Machine and various skid steer loaders. The light weight of the system and small footprint allows this setup to easily be transported from location to location. This also allows the press to access sites where surface conditions will not support a larger machine.

When anchored, the press has 20 tons of hydraulic downforce and 30 tons of pullback. Automatic rate control provides cone advancement at the standard 2 cm per second.

The Membrane Interface Probe is a direct push tool used to log the relative concentration of volatile organic compounds (VOCs) with depth in soil. The MIP was developed by Geoprobe Systems® and is presently manufactured and sold exclusively by Geoprobe Systems® and its distribution agents. The MIP has been used extensively in the U.S. and Europe for mapping the extent of VOC contamination in the subsurface. As a logging tool, the MIP offers many benefits to site investigators.

This probe is robust and percussion drivable (hammerable) with Geoprobe® direct push machines.  Standard HPT probes are equipped with an EC array for measurement of soil electrical conductivity as a complementary log to the HPT log.

The Hydraulic Profiling Tool is a logging tool that measures the pressure required to inject a flow of water into the soil as the probe is advanced into the subsurface. This injection pressure log is an excellent indicator of formation permeability. In addition to measurement of injection pressure, the HPT can also be used to measure hydrostatic pressure under the zero flow condition. This allows the development of an absolute piezometric pressure profile for the log and prediction of the position of the water table. The piezometric profile can be used to calculate the corrected HPT pressure. This data along with the flow rate can then be used to calculate an estimate of hydraulic conductivity (K) in the saturated formation.

Video: OIP Overview

The OIP Probe is constructed with visible and UV LEDs which are directed out the sapphire window.   Logs are typically performed with in UV mode for mapping fuel fluorescence and will switch between the visible and UV light source on rod changes.

he OIP is a tool for mapping light non-aqueous phase liquids (LNAPL), residual LNAPL, and light oils. The OIP system utilizes a 275nm ultraviolet (UV) light emitting diode (LED) to produce fluorescence from the polycyclic aromatic hydrocarbons (PAHs) contained in fuels and light oils. The UV light is directed out a sapphire window in the side of the probe onto the soil. When LNAPL level fuels are present, the PAH molecules will absorb the UV light energy and shortly afterwards emit a light photon (fluorophore) which is the resultant fluorescence. Directly behind the sapphire window, the onboard camera captures images of the soil and any fluorescence produced by hydrocarbon contaminants present. The acquisition software analyzes each pixel of the images taken for the presence of color typical of fuel fluorescence. If there is no fuel present in the formation, or it is not in high enough concentration, then the returned camera image will appear black or dark under the UV light source.
