gamma-ray log
1Gamma ray logging — is a method of measuring naturally occuring gamma radiation to characterize the rock or sediment in a borehole. It is sometimes used in mineral exploration and water well drilling, but most commonly for formation evaluation in oil and gas well… …
2natural gamma-ray log — n a record of the natural radioactivity of the lithologies encountered in the borehole environment. During recording of geophysical logs, the amount of natural radiation is recorded and presented in either counts per second (CPS) or American… …
3Formation evaluation gamma ray — In the field of formation evaluation, gamma ray log records natural radioactivity emission of formation. Measurement of natural emission of gamma rays in oil and gas wells are particularly helpful because shales and sandstones typically have… …

5Log ASCII Standard — (LAS) is a standard File format used commonly in the Oil and Gas Industry to store Log Curve Information. Well logging is used to create a more accurate understanding of the Stratigraphy of an area.A single LAS file can only contain data about… …
6Gamma correction — Gamma correction, gamma nonlinearity, gamma encoding, or often simply gamma, is the name of a nonlinear operation used to code and decode luminance or tristimulus values in video or still image systems. [cite book | title = Digital Video and HDTV …
7geophysical log — n a graphic record of the measured or computed physical characteristics of the rock section encountered in a borehole, plotted as a continuous function of depth. Measurements are made by a sonde which contains the detectors, as it is withdrawn… …
