High-resolution well path description for more accurate trajectory and TVD

The Schlumberger high-definition survey (HDS) service uses continuous inclination measurement to reduce errors associated with conventional surveying. The HDS service surveys as often as every 10 ft, greatly improving on the 100-ft [30-m] survey interval of traditional surveying methods. This process replaces traditional directional survey methods with a high-resolution description of the well path to better capture true borehole trajectory and avoid significant TVD errors. The magnitude of correction and subsequent improvement in TVD is dependent on drilling parameters and the tools deployed.
