DEEPWATER DRILLING AND PRODUCTION SYSTEMS OVERVIEW
The APEA Journal, 1979 The petroleum industry is now involved in a highly significant exploration program to define the hydrocarbon potential of deepwater sedimentary basins. Within the last year, the ability to drill in waters deeper than 1300m has been demonstrated, and exploration plans for water depths down to 1600m have been announced.

Challenges of Drilling Operations in Extreme Deepwater
OTC Brasil, 2017 Abstract This paper highlights the challenges to drilling risers and running equipment for offshore drilling operations from dynamically positioned mobile offshore drilling units (MODUs) in extreme water depths. Whereas nearly all exploratory drilling has occurred in water depths shallower than 3,000-m, Total recently set the water depth
