Abstract
A gravity measuring apparatus is provided comprising a gravitational force detector including a test mass and which produces measurements related to gravitational force exerted on the test mass, characterized in that the gravitational force detector is adapted for use downhole and includes a compensator to compensate for errors in measurements made whilst downhole. The compensator may comprise a guide rail along which the gravitational force detector is moveable over a calibrated distance. Where the test mass is biased toward an equilibrium position about which measurements are made.
