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
