Hand-Portable NMR with Direct Push Deployment Options

Dart™ enables efficient and high-resolution NMR logging in small-diameter borings, either open or PVC-cased, with easy portability to go anywhere it is needed. Dart’s single-person deployment and operation enables measurement in remote or environmentally sensitive locations while eliminating the need for multi-person crews or vehicles.


Dart with Direct Push enables NMR data acquisition for a wide variety of remote field locations with high efficiency and minimized footprint using small rig equipment. Dart is the world’s only NMR logging tool that can be deployed with Direct Push.

Dart yields a high-resolution log of hydrogeologic properties including:

  • Porosity
  • Clay-bound water
  • Capillary water
  • Free water
  • Pore size distribution
  • Hydraulic conductivity

Above the water table, Dart provides direct measurement of moisture content.
