Introduction to Wellbore Positioning

The advent of the ISCWSA brought in a new era in survey practice, improving the realism of error models and hosting a bi-annual forum for industry experts to share ideas and experiences. This project has emerged out of a recognised need for better educational materials to support the understanding of borehole surveying issues.
