Overview:

- Further FT required

- More MWD comparisons

- Independent Gyro confirmation

- Azimuth offset to be solved

- Ensure compliance with MWD std error model

- Develop for MWD surveys

 

Defining the continuous surveying issue

- Low inclination instability
      - Single axis measurement
      - Axial accel cannot measure accurate inclination
      - Swamped by Gravity field

 

Impact of single axis sensitivity
- Additional static surveys required
     - Rig time
     - Wellbore stability
     - Directional control
     - Well construction costs
