Overview:
- Explicit calculation of expansion factors for collision avoidance between two coplanar ellipses is now possible.
- Full details of the algorithms will be presented in the paper SPE 159840 at the ATCE, 8th – 10th October 2012, San Antonio.
- Like-for-like replacement of existing methods
- Satisfies both geometrical and probabilistic constraints
- Neither pessimistic nor optimistic
- Maintains or enhances computational efficiency
- Provided as a toolkit
- Offered for consideration as a replacement industry standard

- Crystallographic studies
- ZPM give the distance of closest approach
- Two-sided expansion is equivalent to an affine transform
- The expansion factor k is proportional to the computed scaling factor
