When employing the borehole gravity meter for remote sensing applications, it is useful to reduce the borehole gravity data to the Bouguer anomaly before interpretation. This paper deals with the calculation and subsequent quantitative interpretation of the borehole Bouguer anomaly. Numerical modeling of lateral density contrasts such as reefs and salt domes are shown to illustrate the effect that these mass distributions have on the bulk density calculated from borehole gravity measurements. The borehole Bouguer anomaly data for several borehole gravity surveys dramatically indicate the presence of inhomogeneities which do not intersect the borehole.
