Introducing the HPT

Vertex would like to introduce it has the ability to measure subsurface permeability in real time using the Hydraulic Permeability Tool (HPT). The HPT is a logging tool that measures the pressure, using a down hole transducer, required to inject a constant flow of water into the soil as the probe is advanced into the subsurface using direct push technology. This injection pressure log is an indicator of subsurface formation permeability. In addition to measurement of injection pressure, the HPT can also be used to measure hydrostatic pressure under zero flow conditions. This allows the development of a hydrostatic pressure graph and prediction of the position of the water table.

Formation hydraulic conductivity can be estimated from HPT logs using a empirical relationships developed for the tool. Data from this hydraulic conductivity estimates is readily transferable to groundwater flow models.
