METHOD TO ASSESS UNCERTAINTIES AND CORRELATIONS RESULTING FROM MULTI-STATION ANALYSIS OF SURVEY DATA |
摘要 |
A system, method and computer-readable medium for a drilling a borehole is disclosed. Errors associated with multi-station survey measurements are obtained and partitioned into a set of estimated errors and a set of considered errors. A post-fit covariance matrix is determined from the estimated errors and includes the effects of the considered errors on the estimated errors. A drilling parameter of a drill string in the borehole may be altered using the determined post-fit covariance matrix. |
