Abstract
Borehole gravity surveys were carried out in the Castle Pines #3, #2, and #1 water wells using the U.S. Geological Survey-LaCoste and Romberg borehole gravity meter (McCulloh and others, 1967a; McCulloh and others, 1967b). The objectives were to estimate the density and porosity of the formations penetrated, and to determine the precision and repeatability of borehole gravity data in shallow wells. A detailed account of field techniques and analysis of data quality has been given by Byerley (1977). This report tabulates the borehole gravity data collected, and presents densities and porosities computed from the subsurface gravity data.
