Extended-reach wells

Extended-reach wells are wells that have relatively long lateral offsets compared to true vertical depth. The term primarily refers to wells restricted to a platform or pad (because of environmental or economic contraints) that are attempting to access reserves at a significant distance from the surface access point.
