Abstract
In August of 1976, borehole gravity surveys were conducted by the U.S. Geological Survey at the Nevada Test Site in three test wells. The U.S. Geological Survey-LaCoste and Romberg borehole gravity meter was used in the logging program. The primary objective of this work was to obtain data for the determination of in situ formation densities utilizing an instrument not significantly affected by casing, borehole rugosity, or other near-borehole conditions. A secondary objective was to obtain duplicate data, by reoccupying subsurface stations, so that the precision and repeatability of borehole gravity data could be studied. Procedures are discussed and data are presented.
