Topside Platform and FPSO

Once exploration wells have confirmed commercially reservoirs of natural gas or petroleum deposits, it is economical to build a permanent offshore production platform from which well completion and oil and gas production can be made. These permanent platforms are often very expensive and generally require large deposits of hydrocarbons to be economical to develop. Some of todays largest offshore platforms are located in the North Sea, where large structures able to withstand high winds and large waves are necessary. There are a number of different types of permanent offshore production platforms, each useful for a particular depth range. This article will give an overview of the most common.

The deepwater portion of Gulf of Mexico has shown a remarkable increase in oil and gas exploration, development and production.  In part this is due to the development of new technologies reducing operational costs and risks, as well as the finding of reservoirs with high production wells.
