System and method for determining placement of a downhole device

Abstract

Data from a well survey includes information on wellbore depth in combination with inclination and azimuth or bending moment taken at measured depth intervals with sufficient short spans to detect micro doglegs in a wellbore over lengths less than, for example, thirty meters. A conversion quantifies micro dogleg severity detected for expression in units of degrees per standardized set length. The converted quantification may also be used in circle-based equations to determine maximum tool length or width for passing tools through the wellbore due to the micro doglegs. Disposing the tool in the wellbore may occur at a location identified to accommodate the tool.
