Borehole gravimetry reviews

Abstract

Figure 1. Graph of gravimetric effects at the axis of cylindrical plates (from McCulloh, 1966, p. 4). measurements are made in deep-sedimentary-basin wells because of the uncertainty of the porosity of the rocks penetrated and the subsequent effect of incorrect values on the thermal conductivities used in the heat-flow calculations. The BHGM should be able to provide the needed porosity values used in these calculations. This would also allow us to better understand the thermal conditions prevailing in these deepsedimentary basins. As borehole gravimetry becomes better understood, more refined, and is used more, other areas of use not listed here will become evident.
