PRODUCT DETAILS
Miniaturized Multi-Component Borehole Sonde String

The DW-150 is a miniaturized, multi-component borehole sonde string utilizing an ultra low-noise digitizer, which enables the recording of low-amplitude microseismic events, 3D-VSP, and crosswell seismic imaging.

Features
24-bit x three-channel digitizer in each shuttle
Ultra low-noise digitizer enables recording of low-amplitude microseismic events, 3D-VSP, Crosswell Seismic Imaging, etc
Slim-hole sonde 1.6 inch OD (<41 mm)
3C sensor packages available: 3C tri-axis orthogonal Geophone
OMNI-2400 high-output Geophone sensors
Machined stainless housing minimizes mechanical resonance for high-resolution, high-frequency recording
Direct connection sub-arrays, armored wireline, or rigid interconnects available with high-pressure multi-conductor booted connectors
Flexible or rigid interconnects may be connected “back-to-back” to form longer intervals
