Intersection Well Phases:
- Navigation
- Objective ; deliver sufficient proximity for detection
- Detection
- Objective ; enumerate relative position
- Decision point – commit to running casing
- Traverse & close
- Objective ; track offset well while drilling to intersection zone
- Intersection
- Objective ; Full bore intersection, incidence angle < 3°, Free running drillstring, Intersect from below
Intersection Geometry
- For conventional hydrocarbon wells “start with the end in mind”
- Lay out a landing zone on offset well; flat & straight
- Reference well intersecting from below
- Geology at intersection
