The Multi-Parameter Sidewall Density Logging Tool contains a
single detector, focused density system using a 200-300 mCi
Cesium 137 source, to record apparent bulk density of the
formation. Additionally, the tool also records natural gamma, caliper,
and a medium guard resistivity, and comes standard with a short arm
and long arm.
