Heli-Rig is one of the rig design concepts for shallow water environments.
1. Independent of water depth. Requires a support structure which in itself would not be helicopter transportable, and therefore could only be used with a minimum of two support structures and a leap-frog operation.
2. Proven technology, but limited drilling capability. Pumping and hoisting capabilities of heli-rigs may not be compatible with well designs.
3. In theory could moved between locations year round, thus circumventing water depth and ice cover limitations.
4. Concept should . . .
