n: a French unit of measurement, equal to 191.833 feet (58.5 metres).

n: Schlumberger wireline tool designed to acquire multilevel triaxial seismic data in cased holes. Provides high quality seismic images in relatively close proximity to the wellbore.

n: Schlumberger wireline tool that digitizes compressional, shear, and Stoneley waveforms and is designed to minimize the discrepancies between sonic and seismic data. Used for porosity evaluation, shear seismic correlation, thin bed detection, fracture pred

n: Wireline logging tool.

(failure/crack development): characteristic markings (ridges, tears, risers, etc.) on fracture surfaces after fatigue crack of fracture propagation (also known as beach marks, clamshell marks, and conchoidal marks).

a steep sided gulley in arid areas that carries runoff, usually at high velocities, for very short times after a rain.
