ABSTRACT:
A downhole apparatus is provided for quickly and accurately estimating the ellipticity of an earth borehole during any drilling operation using circle-based calculations involving statistical analysis of distance measurements made by acoustic sensors. A corresponding method of estimating such ellipticity is also disclosed.
