Abstract:
1. A method for evaluating a characteristic of a region, comprising: disposing proximate the region an apparatus for detecting gamma ray (GR) radiation, the apparatus comprising a plurality of detector cells arranged in an array, each cell comprising a housing having two opposing apertures, the housing comprising a GR absorbing material, and a GR detector disposed within the housing such that external gamma rays are received at the GR detector via the aperture, wherein the apertures of each cell are aligned with a defined spacing for high resolution GR detection; rotating the array of detector cells relative to a stratigraphic bed; receiving gamma rays at the apparatus via the plurality of apertures; receiving double count rates of gamma rays arising from each of the two opposing apertures; analyzing the received gamma rays to provide high resolution measurement of the characteristic of the region; and analyzing the received gamma rays to determine the strike azimuth of the stratigraphic bed.
