20140163888 | Weighting Function For Inclination And Azimuth Computation - A method, system, and computer readable medium is disclosed to estimate a survey parameter (e.g., attitude) for a drilling operation in a subterranean formation. The survey parameter is calculated using multiple methods with the results of the different methods weighted to improve the accuracy at a given attitude of the tool and angular velocity of the sensor package. Results from the different methods are combined based on a weighting function to generate the improved values of inclination and azimuth. Specifically, the values of the weighting function depend, linearly or non-linearly, on the attitude of the tool and quality of the survey data. In one scenario, the attitude of the tool is approximated by the most recently obtained static inclination/azimuth. In addition, the quality of the survey data is approximated by a measure of vibration severity that is represented by the number of good data points based on the roll rate. | 06-12-2014 |

20150377004 | Closed Loop Control of Drilling Toolface - A downhole closed loop method for controlling a drilling toolface includes measuring first and second attitudes of the subterranean borehole at corresponding first and second upper and lower survey stations.

The computed angle change is compared with a predetermined threshold. This process may be continuously repeated while the angle change is less than the threshold. The first and second attitudes are further processed downhole to compute a toolface angle when the angle change of the subterranean borehole is greater than or equal to the threshold. The toolface angle may then be further processed to control a direction of drilling of the subterranean borehole. | 12-31-2015 |
