n: the analysis of subsurface formation characteristics, such as lithology, porosity, permeability, and saturation, by indirect methods such as wireline well logging or by direct methods such as mud logging and core analysis.

the analysis of formation character or properties, usually by remote logs.

n: the recording of subsurface characteristics by wire line (actually conductor line) tools. Wireline well logs include acoustic logs, caliper logs, radioactivity logs, and resistivity logs.

A continuous measurement of formation properties with electrically powered instruments to infer properties and make decisions about drilling and production operations. The record of the measurements, typically a long strip of paper, is also called a log.
