  • Wellbore caliper measurement method using measurements from a gamma-gamma density
    Patent number: 6552334
    Abstract: Methods are disclosed for determining the standoff of a well logging instrument from the wall of a wellbore and the shape of the wellbore itself. The methods include measuring a compensated gamma-gamma formation density at a rotary orientation proximate a bottom of the wellbore, and measuring an apparent density at at least one other rotary orientation. The apparent density is related to the compensated density, a density of a fluid disposed between the logging instrument and a wall of the wellbore, and the standoff. Repeated measurements at a plurality of axial positions along the wellbore provide a log of the wellbore.
