Abstract
The vibrating string downhole gravity meter described has a precision of about .01 mgal in gravity measurement. With measurements of this precision, density of a 30‐ft section in the subsurface can be determined with an accuracy of [Formula: see text]. These density measurements are useful in gravity interpretation, in computing acoustic impedance for use in seismology, and in estimating porosities of formations. Examples of density profiles measured in boreholes are given.
