MATECO – Geotechnical and Environmental DRILLING

What is Hydraulic Profiling Tool (HPT)?

MATECO is excited to bring to the table another state-of-the-art tool to provide our clients with accuracy on site investigations.  Our vendor partnership over the years with Geoprobe® Systems located in Kansas has greatly assisted us in growing our business with their family of products for various drilling services.

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 down-hole transducer to measure the pressure response of the soil to injection of water at a constant rate (less than 300 mL/min) while automatically measuring the resulting formation pressure with depth.  One primary use of this tool is to locate and define preferential migration pathways for contaminants in the subsurface.  It can also be used to target zones for injection of remediation material.  In addition, the HPT can be used to select well screen intervals, evaluate locations to conduct slug tests, and measure static water conditions across a site.
