Abstract: A drilling tool in accordance to one or more aspects includes a processor and a steering device. The processor determines a demand attitude and an instantaneous drilling tool attitude, evaluates a control law to derive a control law tool face, and converts the control law tool face to an equivalent tool face. The steering device applies the equivalent tool face to control a drill attitude of the drilling tool.

Abstract: A method for drilling a subterranean wellbore includes rotating a drill string in the subterranean wellbore. The drill string includes a drill collar, a drill bit, and survey sensors (e.g., a triaxial accelerometer set and a triaxial magnetometer set) deployed therein. The triaxial accelerometer set and the triaxial magnetometer set make corresponding accelerometer and magnetometer measurements while drilling (rotating). These measurements are synchronized to obtain synchronized accelerometer and magnetometer measurements and then further processed to compute at least an inclination and an azimuth of the subterranean wellbore while drilling. The method may further optionally include changing a direction of drilling the subterranean wellbore in response to the computed inclination and azimuth.

Abstract: An attitude hold controller method includes receiving at a navigable apparatus a demand inclination and a demand azimuth with respect to a global coordinate system and determining at the navigable apparatus a demand attitude vector according to the received demand inclination and the demand azimuth. Determining at the navigable apparatus a current navigable apparatus attitude vector. Evaluating a control law using the current navigable apparatus vector and the navigable apparatus demand attitude to derive a control law tool face, converting the control law tool face to an equivalent tool face, and applying the equivalent tool face with the navigable apparatus to control the navigable apparatus attitude.

Abstract: A method for automatically evaluating a survey of a subterranean wellbore includes receiving downhole navigation sensor measurements and automatically evaluating surface sensor data obtained at substantially the same time as the navigation sensor measurements to determine whether or not the navigation sensor measurements were obtained during satisfactory wellbore survey conditions. The navigation sensor measurements are evaluated to determine whether or not they meet certain predetermined conditions necessary for obtaining a satisfactory survey. A survey recommendation is automatically generating based on the automatic evaluations performed.
