  • AZIMUTH INITIALIZATION AND CALIBRATION OF WELLBORE SURVEYING GYROSCOPIC AND INERTIAL INSTRUMENTS BY MEANS OF AN EXTERNAL NAVIGATION SYSTEM
    Publication number: 20120245850
    Abstract: It is described a system and a method for for azimuth initialization of a gyroscopic and/or inertial instrument for wellbore surveying, said system comprising:—a rigid reference structure to which the gyroscopic and /or inertial instrument is rigidly connectable;—an external navigation system for providing an azimuth measurement as a function of time, and wherein the rigid reference structure provides a rigid orientation between the external navigation system and the gyroscopic and/or inertial instrument; —a processor operable to synchronize the azimuth measurement as a function of time with an orientation as a function of time of the gyroscopic and/or inertial instrument.

  • Method of combining spatial models
    Patent number: 7149672
    Abstract: A method is provided of combining first and second models of a common region of space, such as a region of the earth below the surface, to form a third model. Common points have different positions in the first and second models. A predetermined correlation exists between the positions of the common points in the first model and the positions of points of interest in the first model. The positions of the common points in the third model are derived from the common point positions in the first and second models. The positions in the third model of the points of interest are derived from the positions of the common points in the third model and from the predetermined correlation.
