Deepwater production is noteworthy for widely dispersed surface structures supplemented with subsea systems. In the past 30 years, the total number of Gulf of Mexico platforms declined by 50% while the oil production doubled. Of course, this level of production is not sustainable without regular lease sales and increased exploration. In that regard, the signs are not good.
435 GoM shelf platforms have been removed in just the last 5 years (2017-2021). The loss of platforms is accompanied by a loss of marine habitat that the rigs-to-reefs program has partially compensated for. There have been a number of other interesting proposals for the use of old platforms, some more serious than others.
Current number of Gulf of Mexico platforms by water depth:
| water depth | floating and fixed production platforms |
| all depths | 1757 |
| >400 m | 52 |
| >1000 m | 35 |
| >1500 m | 16 |
| >2000 m | 7 |
