Hydraulic Profiling Tool (HPT)
High‑resolution subsurface intelligence for confident groundwater decisions
Legion Drilling’s Hydraulic Profiling Tool (HPT) delivers continuous, real‑time data that reveals the true hydraulic behaviour of the subsurface — even when traditional drilling methods show uniform or misleading results. With vertical resolution as fine as 1.5–3 cm, the HPT identifies thin permeable layers, perched groundwater, and subtle stratigraphic changes that directly influence groundwater flow.
Why Choose HPT?
High‑resolution vertical profiling
The HPT collects continuous data at centimetre‑scale intervals, allowing our team to detect thin gravel lenses, sand seams, and preferential flow paths that drill cuttings and core samples often miss.
Real‑time hydraulic response
By measuring injection pressure at a controlled flow rate, the HPT provides immediate insight into formation permeability — helping you make informed decisions on site.
Electrical conductivity (EC) mapping
EC data helps distinguish lithology and porewater chemistry, improving interpretation of complex subsurface conditions.
Accurate hydraulic conductivity (K) estimates
The combination of pressure and flow behaviour produces reliable K‑values, highlighting zones where groundwater actually moves.
