    Abstract: medição aprimorada de radiação gama de fundo de poço através de redução de dispersão de compton trata-se de sistemas, métodos e dispositivos para avaliar uma formação de terra cortada por um furo de poço. o método inclui usar um primeiro componente responsivo à radiação para detectar raios gama que têm uma energia abaixo de uma energia-limite; usar um segundo componente responsivo à radiação configurado para detectar raios gama que atravessam o primeiro componente responsivo à radiação; gerar um espectro de raios gama de compton reduzido gerando-se um espectro de raios gama de anticoincidência indicativo dos raios gama detectados pelo primeiro componente responsivo à radiação e dos raios gama detectados pelo segundo componente responsivo à radiação. o espectro de raios gama de anticoincidência representa aqueles raios gama dentre os raios gama detectados pelo segundo componente responsivo à radiação que não são detectados na coincidência com os raios gama detectados pelo primeiro componente responsivo à radiação.

    Abstract: Methods, systems and devices for estimating a parameter of interest from a gamma ray spectrum relating to a volume of matter using standard gamma ray spectra from reference samples, wherein there is at least one non-elemental characteristic that is different between the volume and at least one of the reference samples, wherein the non-elemental characteristic difference affects gamma ray interactions. Methods may include deconvolving a gamma ray spectrum obtained from the analysis volume into a plurality of elemental spectral yields, wherein deconvolution includes compensating for effects of the non-elemental characteristic difference. Methods may include using at least one compensation standard spectrum configured to compensate for the effects of the non-elemental characteristic of the at least one of the reference samples.

    Abstract: One general embodiment according to the present disclosure may be formation evaluation tool for detecting radiation in a borehole in a volume of an earth formation. The tool may include a detector including a monolithic scintillation element comprising a coherent assemblage of joined fibers, wherein the fibers are made of an optically transparent scintillation media. The fibers may be at least one of i) gamma ray responsive; and ii) neutron responsive. The coherent assemblage of fibers may be a continuous mass, may be heat-joined. The fibers may be solid. The scintillation media may comprise at least one of i) organic crystalline scintillation materials, ii) amorphous glass, and iii) nanostructured glass ceramics. The coherent assemblage of fibers may be asymmetric. The coherent assemblage of fibers may surround a further scintillation media having different scintillation characteristics than the scintillation media. The scintillation element may be azimuthally sensitive.

    Abstract: Systems, methods and devices for evaluating an earth formation intersected by a borehole. The method includes using a first radiation responsive component to detect gamma rays having an energy below a threshold energy; using a second radiation responsive component configured to detect gamma rays that traverse the first radiation responsive component; generating a reduced-Compton gamma ray spectrum by generating an anticoincidence gamma ray spectrum indicative of the gamma rays detected by the first radiation responsive component and the gamma rays detected by the second radiation responsive component. The anticoincidence gamma ray spectrum represents those gamma rays of the gamma rays detected by the second radiation responsive component that are not detected in coincidence with the gamma rays detected by the first radiation responsive component.
