Under this agreement, Geoprobe is now the exclusive distributor for Vista Clara’s Dart™ Direct Push Nuclear Magnetic Resonance (NMR) logging instruments in national markets in North America, Central America, and Columbia.

Nuclear magnetic resonance (NMR) is a powerful technology that provides direct and non-destructive detection of hydrogen in the formation fluids. Direct Push NMR logging can be performed in a variety of remote and not easily accessible areas providing robust, highly efficient, and high-resolution measurements of hydrogeologic properties of native formation.

In comparison to conventional DP methods, DP-NMR provides a direct measurement of volumetric water content as well as bound and mobile porosity, differentiation between different soil and sediment types, and estimation of hydraulic conductivity values in the range of 0.001 m/day to over 1000 m/day, which covers a range of much higher hydraulic conductivity than HPT tool measurements (HPT sensitivity limit is 30 m/day).

Vista Clara is the world’s leading developer and manufacturer of NMR technologies for groundwater and environmental investigations. Vista Clara provides a wide range of NMR tools for in-situ NMR measurement of hydrogeological properties, including the Javelin® wireline NMR logging tools, Dart™ person-portable NMR logging tools, and most recently Dart™ Direct Push NMR tools. Vista Clara’s broad line of low-cost small diameter NMR logging technologies are enabling high-resolution In-situ NMR measurements to be used in a wide range of subsurface investigations, for the benefit of industries that could previously not access NMR logging technologies, including: environmental remediation, groundwater resources, geotechnical engineering and mining.

Geoprobe is a global leader in Direct Push machines and tooling for high-resolution site characterization, groundwater, and environmental remediation markets. Direct Push methods enable tools to be pushed into the ground by displacing the soil and creating minimal disturbance to the native formation. These methods do not require rotary drilling and greatly reduce or eliminate soil cuttings, reducing overall project time and cost.
