Megaprojects won't be on shelf long

With the largest oil companies starting to back away from the megaproject, the result could mean a greater focus on shale. Production from the average shale well is a fraction of a deepwater well, for example, and output also suffers from dramatically sleeper decline rates compared to offshore. However, drilling shale wells can cost a few orders of magnitude less than a large-scale offshore project That feature is hard to overemphasize in today's oil-pricing environment.
