(Extract from SLB industry article “the defining Series – Multilateral wells)

The geometry of an ML well is determined by the production targets, their relative depths and lateral extents. The laterals may be on the same horizontal plane at the same true vertical depth or they may be on the same vertical plane and follow the same direction but at different depths. Within these two main categories, a nearly infinite number of combinations can be created that may cover multiple zones or span out in various directions within a single reservoir
