Survival of the fittest or overcrowding?
If you’ve been involved in drilling boreholes in your career, you’ll be familiar with desurvey. Desurvey is the process of converting a directional well survey — which provides measured depth, inclination and azimuth points from the borehole — into a position log. The position log is an arbitrarily finely sampled set of (x, y, z) points along the wellbore. We need this to convert from measured depth (distance along the borehole path) to depth in the earth, which…
