Abstract
For some embodiments, a software application for correcting sensor data in a remote database (114, 118) according to magnetic correction parameters obtained from a geophysical survey service, the sensor data obtained from directional instruments on a well tool (107, 108, 110). The remote database resides in a field computer (112) at a well site, and a copy of the remote database may also reside in a real time operations computer system. For some embodiments, the sensor data for particular depths and measurement times are stored as rows in a table (FIG. 3). The correction software may write new rows in the remote database with the corrected sensor data, or may write new rows in a second database for storing corrected sensor data (FIG. 1).
