Claim Text:
1. A method to correct data obtained from sensors on a well tool, comprising: making measurements using a sensor on a well tool in a well, generating sensor data associated with a depth within the well and a measurement time of the sensor data, the sensor being a sensor that provides signals to derive directional data; retrieving, under control of a processor, magnetic correction parameters over a network from a remote database; retrieving under control of the processor, from a first computer system located remotely from and associated with a plurality of geographically separated well sites, the sensor data associated with the depth within the well and the measurement time of the sensor data, the well being at a well site of the plurality of geographically separated well sites, the first computer system and the plurality of geographically separated well sites being separate and remote from the remote database; correcting the sensor data by using the processor to transform the sensor data into corrected sensor data according to the magnetic correction parameters; writing, under control of the processor, the corrected sensor data to a database of the first computer system and to each database of a plurality of geographically separated computers, the plurality of geographically separated computers being separate and remote from the remote database; and controlling directional drilling at one or more of the geographically separated well sites based on the corrected sensor data written into the databases of the first computer system and the plurality of geographically separated computers associated with the one or more of the geographically separated well sites at which the direction drilling is being controlled.
