A Compensated Spectral Natural Gamma Ray* Logging System
Abstract
A Compensated Spectral Natural Gamma Ray Logging System has been designed, which incorporates active compensation for differences in borehole conditions into the calculation of the potassium (K), uranium (U) and thorium (Th) elemental concentrations. A low atomic number tool case allows gamma rays in the photo-electric energy region to be detected, which permits additional measurements of formation lithology in open holes and casing thickness in cased wells. The least squares calculation for the elemental concentration gives excellent agreement in open and cased hole comparisons.
