Deepwater Gulf of Mexico - America's Expanding Frontier

DRILLING AND DEVELOPMENT
Deepwater drilling occurs from mobile offshore drilling units (MODU�s), 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 MODU�s. 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.
