Deepwater Gulf of Mexico - America's Expanding Frontier

DRILLING AND DEVELOPMENT
Deepwater drilling occurs from mobile offshore drilling units (MODUís), such as semisubmersible units or drillships (figures 29 and 30), and from platform rigs.
Figure 31 depicts deepwater rigs operating in the GOM from 1992 through 2003.1
There was a steady increase in the average number of rigs operating from 1992 to a peak in 2001.
Most, if not all, of the deepwater-capable drilling rigs are under long-term contractual arrangements. The reader is cautioned
not to draw any conclusions from the rig count differences between figures 31 and 32.
1 It is important to note that the rig count includes platform rigs operating on deepwater production facilities in addition to the MODUís. About one-third of all rigs are platform rigs. The numbers do not distinguish between rigs drilling and those in service for completion and workover operations.
