gamma ray logging
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… …
2Formation 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… …
