n: Schlumberger wireline tool that measures phase shift and attenuation of a 1100 MHz wave. Used for Hydrocarbon identification independent of formation water salinity, thin bed detection, Hydrocarbon saturation and mobility and to evaluate invaded zones.

When a form of energy is propagated through a medium, its amplitude (energy level) is decreased. This decrease is termed attenuation.

electromagnetic propagation tool. Measures propagation time and attenuation rate of microwave energy through the formation. Helps distinguish between oil and water.
