ARM’s logging system is mounted on a four wheel drive F350 diesel truck that is small and mobile, which allows it to reach wells easier than much larger logging trucks. The truck provides state of the art logging capabilities including a full suite of standard logging tools and optical televiewer (OPTV) and acoustical televiewer (ATV), neutron, gamma, and heat pulse flowmeter.

Some of the important information obtained from logging or imaging includes

• Lithology, thickness, & lateral continuity of aquifers and confining layers.


• Structural information such as strike and dip of lithologic contacts and bedrock fractures.


• Hydrogeologic information including identification of water producing & receiving zones, flow rate measurements, and estimates of permeability, porosity, moisture content, and specific yield.


• Engineering properties such as bulk density, Poisson’s Ratio, Young’s Modulus, Bulk Modulus & Shear Modulus.
