Wellbore surveys provide definitive data that depict the position of a borehole or well path in three-dimensional space.

Sperry Drilling services' wellbore surveying service delivers a comprehensive well positioning approach, generating the necessary risk versus reward analysis and survey program.

Sperry can also help ensure survey executions per expectations and provide a one-stop shop for well position information.

•Early analysis of well position requirements.

•Evaluation of risk versus reward and creation of a survey program.

•Help ensure wellbore construction surveys meet operator and well position expectations.

•Capture of lessons learned regarding wellbore placement.

•Load wellbore data into definitive database.

•Reporting and distribution of final survey.

Benefits

•Eliminates the need to use wireline gyros to orient or steer the drilling assemblies, which saves considerable rig time and provides for safer operations.

•Rate gyro accuracy assures precise wellbore guidance for collision avoidance and precise trajectory placement.

•Unaffected by magnetic interference, the sensors can run closer to the bit in the MWD string by eliminating the need for non-magnetic spacing collars for the gyro sensor.

•The tool's modular design allows it to be placed anywhere in the drill collar.

•The tool may be run with either positive pulse or negative pulse telemetry systems.
