HYDRAULIC CONDUCTIVITY TRANSMISSIVITY

MEASURE GROUNDWATER DIRECTLY

JAVELIN® The Magic of MRI Adapted for Groundwater

Designed specifically for groundwater investigations, Javelin® borehole Magnetic Resonance (MR) logging tools provide the highest resolution characterization of aquifer properties possible. Capable of collecting data down to 1600m (5200ft), Javelin’s powerful permanent magnets polarize hydrogen nuclei of water molecules. Simultaneous multifrequency operation speeds up logging time while ensuring the sensitive zone is outside the zone disturbed by drilling.

Measure Hydrogeologic Properties Directly

Javelin provides high-resolution measurement of volumetric fluid content in the native formation. It is directly sensitive to the pore size distribution, bound vs mobile fluid in porous space, and provides quantitative estimates of porosity and hydraulic conductivity.

The Confidence of Multiple Measurement Shells

The Magnetic Resonance Advantage

Javelin incorporates a Magnetic Resonance (MR)-based technology that uses the same physics as medical MRI. This technology provides inherently non-destructive detection of water, using static and alternating magnetic fields to polarize and excite hydrogens in the native formation fluids out past the annular space. The initial amplitude of the MR signal observed after this perturbation is linearly proportional to the volumetric fluid content, or porosity if the formation is saturated. MR relaxation times are strongly correlated with the size of the pore space and are used to distinguish between water bound in small pores from more mobile water in large pores and fractures.

All Javelin borehole logging tools incorporate multi-frequency operation. This enhanced versatility enables it to see radially outward in multiple measurement shells during a single log. This multi-frequency capability, combined with Javelin’s unique ability to operate below the commercial AM broadcast band, provides greatly increased immunity against electromagnetic interference and faster logging speeds than singlefrequency-based MR tools.

JAVELIN® Magnetic Resonance Wireline Logging Tools

Boasting a wide range of tool diameters, the Javelin® product family fits most any well or borehole size. Interchangeable lower probe sections enable flexible operations and reduce capital equipment costs.

JAVELIN® BOREHOLE LOGGING TOOLS

Max

Ideal for medium to large size borings up to 460mm (18 inches) in diameter, Javelin Max includes three frequency operation for the fastest logging speed and highest SNR possible. The Max is an exceptional tool for well design, aquifer storage & recovery, and brine mining. An integrated Gamma sensor is optional.

Slim

Popular for small and medium-diameter boreholes from 75mm to 300mm (3 to 12 inches) diameter, the Javelin Slim system is routinely used in mining, geotechnical, and groundwater explorations. The Slim system incorporates two-frequency operation with optional Gamma sensor.

Micro

The world’s smallest diameter wireline MR logging tool. It is perfect for logging within existing 50mm (2 inch) PVC-cased monitoring wells, which are very common in environmental remediation and groundwater monitoring wells.

Javelin Surface Station

The Javelin surface station operates all Javelin tools. It provides tool power, control, telemetry, and

interfaces to depth encoder and tension sensors.
