Well blowouts can occur during the drilling phase, during , during well , during production, or during activities. Blowouts can eject the out of the well, and the force of the escaping fluid can be strong enough to damage the . In addition to oil, the output of a well blowout might include natural gas, water, drilling fluid, mud, sand, roc. The blowout and fire resulted from an explosion within the swab tree assembly located at the top of the well. More specifically, an explosive environment that had been created through a mixing of hydrocarbons and air was ignited, but the source of the ignition could not be definitively determined.
[pdf] Jackup rigs are so named because they are self-elevating with three, four, six and even eight movable legs that can be extended (“jacked”) above or below the hull. Jackups are towed or moved under self propulsion to the site with the hull lowered to the water level, and the legs extended above the hull. The hull is actually a water-tight barge that floats on the water's surface. When the rig reaches the work site, the crew jacks the legs downward through the water and int.
[pdf] Offshore platforms have many uses including oil exploration and production, navigation, ship loading and unloading, and to support. .
There are two types of offshore drilling rings/platforms. The first type is moveable offshore drilling rigs that can be moved from one place to another and the second type is the fixed rigs/platforms. .
Different types of offshore oil rigs and platforms are used depending on the offshore oil/gas field water-depth and situation. Rigs are used for the drilling of the wells and platforms are installed in the field for extracting oil/gas operation. Main types of rigs and. .
Drilling barges are used mostly for inland, shallow water drilling. This typically takes place in lakes, swamps, rivers, and canals. Drilling barges are.
