Abstract
An improved method and apparatus for determining wellbore position in deviated or horizontal wells. Continuous inclination values captured while drilling can be used to provide a more accurate model of a wellbore path, particularly true vertical depth, than would be produced using conventional methods of measuring inclination only at static survey points.
