..., the gamma ray detector is centered in the MWD collar and the latter is assumed to be centered in the borehole filled with drilling mud. Correction charts for each tool size have been generated with the data normalized to an 8" MWD collar centered in a 10" borehole filled with 10 lb/gal mud surrounded...
