Overview:
- Wellbore Geometries and Collisions
- Wellbore Separation Requirements
- Probability Distributions
– normal distributed data
– empirical survey data
- Comparison of Collision Probabilities
The Collision Probability is the probability density integrated over the appropriate area/volume of the probability density. The Probability Density of the relative wellbore positions is illustrated by the concentric ellipses/ ellipsoids.
