A wellbore survey tool and methods for estimating a direction of highest gamma ray intensity of a gamma ray distribution are provided. The tool includes a body having a center axis. The body is configured to be placed within a wellbore. The tool further includes a plurality of gamma ray detectors within the body. Each detector of the plurality of gamma ray detectors has a direction of maximum gamma ray sensitivity with the direction having a non-zero component perpendicular to the center axis. The non-zero components of the plurality of gamma ray detectors are spaced circumferentially about the center axis.

Systems and methods are provided for producing a continuous survey of a previously drilled portion of a wellbore. The method includes receiving a plurality of stationary survey measurements taken at a corresponding plurality of locations along the portion of the wellbore. The method further includes receiving at least one continuous survey including a plurality of continuous survey measurements taken between a pair of stationary survey measurements of the plurality of stationary survey measurements. The method further includes combining the plurality of stationary survey measurements and the plurality of continuous survey measurements to produce the continuous survey of the portion of the wellbore.


A system and method for providing information regarding the tortuosity of a wellbore path is provided. The method includes receiving data from a plurality of survey stations of a wellbore survey. The method further includes defining a plurality of reference lines for the wellbore path. The method further includes determining a plurality of displacements of the wellbore path from the plurality of reference lines.


A system and method for providing information regarding the tortuosity of a wellbore path is provided. The method includes receiving data from a plurality of survey stations of a wellbore survey. The method further includes determining a plurality of tortuosity parameter values for the wellbore path within a corresponding plurality of analysis windows, wherein each analysis window has at least one tortuosity parameter value.


Systems and methods for monitoring the tool rotation of a survey tool 320 within a wellbore 312 during a gyrocompassing survey measurement are provided. A plurality of signals from at least one accelerometer module 330 of the survey tool 320 is indicative of measurements of the Earths gravitation vector taken by the at least one accelerometer module 330 during the gyrocompassing survey measurement. The plurality of signals is used to calculate a tool face rate of change of the survey tool with respect to the wellbore during the gyrocompassing survey measurement.

Systems and methods are provided for producing a continuous survey of a previously drilled portion of a wellbore. The method includes receiving a plurality of stationary survey measurements (212a, 212b) taken at a corresponding plurality of locations along the portion of the wellbore. The method further includes receiving at least one continuous survey (214) including a plurality of continuous survey measurements taken between a pair of stationary survey measurements of the plurality of stationary survey measurements. The method further includes combining the plurality of stationary survey measurements and the plurality of continuous survey measurements to produce the continuous survey (512) of the portion of the wellbore.


A method and an apparatus are provided for determining an orientation of a tool with respect to a reference direction. The tool is configured to be moved along a wellbore and to generate information usable to determine an orientation of the tool. At least one first signal is indicative of an orientation of a directional reference system with respect to the reference direction. Information regarding a relative orientation of the tool with respect to the directional reference system is used to determine the orientation of the tool with respect to the reference direction in response at least in part to the at least one first signal.


Systems and methods for the down-hole automatic mechanical coupling and alignment of a first sensor module and a second sensor module are provided. A mating element of a first sensor module includes a sheath with a first cam and a shroud surrounding the first cam. A second mating element of a second sensor module includes a second cam complementary to the first cam. Upon mating, the sheath surrounds at least a portion of the second mating element and the first cam seats against the second cam, with a predetermined axial orientation with respect to each other.
