dc.description.abstractAn evaluation is made of radioactivity logging as applied to the exploration drilling program on the Colorado Plateau. The compilation of data presented gives a preliminary insight into the possibilities of the technique being applied. A comparison has also been made at the results obtained by the logging units of the U. S. Geological Survey, The Texas Company, and the Colorado Exploration Branch. The work performed by the Commission has demonstrated that it is possible to utilize a gamma-ray log for geologic interpretation and for obtaining approximate assay values. Gamma-ray logging is a definite aid to exploratory drilling in detecting radioactivity anomalies and providing an accurate geologic log. Extensive application of this technique may reduce the over-all cost of drilling through reduction of the amount of coring required and make possible a close coordination of geologic planning with the drilling operation. Operational logging and experimentation have proved that equipment now being used by the Colorado Exploration Branch provides satisfactory operation in the following respects: (1) provides sufficient sensitivity, (2) gives a linear response, (3) reproduces a log when re-runs are made in the same hole several days apart and under dissimilar weather conditions, (4) produces a log in which the statistical fluctuations do not affect the interpretation, and (5) has an adequate range of sensitivity scales. It has been demonstrated that a single logging unit, with provision for field maintenance, can log the total footage being drilled on a project today. It is concluded that a complete gamma-ray logging service will be a decided asset to the exploration drilling program.
