Barge rigs work in shallower waters, usually less than 20 feet deep. After being floated to the drilling location, the hull is brought to rest on the ocean floor, creating a stable platform for drilling. Many barge rigs operate in the Gulf of Mexico and around the world. .
In waters too deep for a barge, but less than 50-70 feet deep, a submersible rig can be used. Columns or posts are submerged into the water and filled to specific levels that determine. .
As we move into deeper waters, a mobile platform called the “jack-up” rig comes into play. It gets this name because it can be moved directly over the location to drill or pump oil. The. .
Many offshore oil rigs are anchored platforms. They use a steel framework anchored to the ocean floor as a foundation for a surface drilling rig, equipment, and living quarters. Platforms may drill in many directions from this base, and they are broken down into specific types suited for various depths. .
In very deep water, it is not practical to attach an offshore rig to the bottom of the ocean. Floating oil rigs are kept in place by anchors or dynamic positioning systems that keep them over target. There are several types of floaters in use at various deep water drilling locations worldwide.
[pdf] Deepwater drilling, or deep well drilling, is the process of creating holes in the using a for under the deep sea. There are approximately 3400 deepwater wells in the with depths greater than 150 meters. Deepwater drilling has not been technologically or economically feasible for m.

Using sonic equipment, oil companies determine the drilling sites most likely to produce oil. Then they use a mobile offshore drilling unit (MODU) to dig the initial well. Some units are converted into production rigs, meaning they switch from drilling for oil to capturing oil once it's found.Types of deepwater drilling facilitiesDrilling in deep waters can be performed by two main types of mobile deepwater drilling rigs: drilling rigs and . Drilling can also be performed from a fixed-position installation such as a fixed platfor. .
On 20 April 2010, a deepwater oil rig () exploded, killing 11 and releasing 750,000 cubic meters (200 million gallons) of oil into the Gulf of Mexico. With those numbers, many scientists c. .
