Abstract
A method of surveying a wellbore continuously during drilling. The method includes using a drill string with a non-rotating sub-assembly. The non-rotating sub-assembly comprises three accelerometers oriented orthogonally to each other and three directional sensors also oriented orthogonally to each other. Sample measurements from the six sensors are used to calculate the attitude of the wellbore and more specifically used to create an accurate survey of wellbores within a subterranean formation while the drill string is drilling.
